Frequently Asked Questions - Infinity 225 954556 Telwin

Which welding processes does the Telwin Infinity 225 support?

The machine supports TIG welding in direct current (DC) and alternating current (AC) with HF or LIFT ignition, as well as MMA welding (covered electrodes).

How to perform HF ignition?

Bring the tungsten electrode tip to 2-3 mm from the workpiece without contact, then press the torch button. A high-frequency spark ignites the arc. Once the arc is lit, form the weld pool.

How to adjust the current in TIG mode?

Use the multifunction knob on the front panel. In TIG mode, it allows you to adjust the main current I2, base current I1, frequency, balance, slopes, and pre/post gas times.

Which electrode to use for welding aluminum?

For AC TIG welding of aluminum, use a pure tungsten electrode (green color band). Adjust the AC balance to optimize oxide cleaning.

How to avoid electrode sticking in MMA welding?

The machine is equipped with Hot Start (initial overcurrent) and Anti Stick functions that reduce sticking. Also adjust the Arc Force for a smoother arc.

What to do if the machine overheats?

The thermal protection activates and the yellow indicator lights up. Turn off the machine and let it cool naturally. Respect the duty cycle (intermittence) indicated on the plate. Check that the fan is working properly.

How to connect the argon gas cylinder?

Screw the pressure regulator onto the cylinder valve. Connect the gas hose between the regulator and the fitting at the back of the machine. Open the cylinder and set the flow rate (l/min) according to the indicative table. Close the valve after use.

What accessories are available for this machine?

Optional: remote control (1 or 2 potentiometers or foot pedal), TIG torch with potentiometer, MMA kit, TIG kit, bottle adapter, pressure regulator, America cart, auto-darkening helmet.

How to clean the inside of the welding machine?

Unplug the machine and open the panels. Use a jet of compressed air or a suitable solvent to remove dust from the electronic boards. Check the tightness of connections and the condition of cables. Carefully reassemble the panels.

1. GENERAL SAFETY CONSIDERATIONS FOR ARC WELDING

The operator should be properly trained to use the welding machine and should be informed about the risks related to arc welding procedures, the associated protection measures and emergency procedures.

(Please refer to the applicable standard "EN 60974-9: Arc welding equipment. Part 9: Installation and Use).

- Avoid direct contact with the welding circuit: the no-load voltage supplied by the welding machine can be dangerous under certain circumstances.

- When the welding cables are being connected or checks and repairs carried out the welding machine should be switched off and disconnected from the power supply outlet.

- Switch off the welding machine and disconnect it from the power outlet before replacing consumable torch parts.

- Make the electrical connections and installation according to the safety rules and legislation in force.

- The welding machine should be connected only and exclusively to a power source with the neutral lead connected to earth.

- Make sure that the power supply plug is correctly connected to the protection outlet.

- Do not use the welding machine in damp or wet places and do not weld in the rain.

- Do not use cables with worn insulation or loose connections.

- Do not weld on containers or piping that contains or has contained flammable liquid or gaseous products.

- Do not operate on materials cleaned with chlorinated solvents or near such substances.

- Do not weld on containers under pressure.

- Remove all flammable materials (e.g. wood, paper, rags etc.) from the working area.

- Provide adequate ventilation or facilities for the removal of welding fumes near the arc; a systematic approach is needed in evaluating the exposure limits for the welding fumes, which will depend on their composition, concent and the length of exposure itself.

- Keep the gas bottle (if used) away from heat sources, including sunlight.

- Use electric insulation that is suitable for the torch, the workpiece and any metal parts that may be placed on the ground and nearby (accessible). This can normally be done by wearing gloves, footwear, head protection and clothing that are suitable for the purpose and by using insulating boards or mats.

- Always protect your eyes with the relative filters, which must comply with UNI EN 169 or UNI EN 379, mounted on masks or use helmets that comply with UNI EN 175.

Use the relative fire-resistant clothing (compliant with UNI EN 11611) welding gloves (compliant with UNI EN 12477) without exposing the skin to the ultraviolet and infrared rays produced by the arc; the protection extend to other people who are near the arc by way of screens (reflective sheets.

- Noise: If the daily personal noise exposure (LEPd) is equal to or higher than 85 dB(A) because of particularly intensive welding operations, suitable personal protective means must be used (Tab. 1).

- The flow of the welding current generates electromagnetic fields around the welding circuit.

Electromagnetic fields can interfere with certain medical equipment (e.g. Pacemakers, respiratory equipment, metallic prostheses etc.).

Adequate protective measures must be adopted for persons with these types of medical apparatus. For example, they must be forbidden access to the area in which welding machines are in operation.

safelywelding machine conforms to technical product standards for exclusive use in an industrial environment for professional purposes. It does not assure compliance with the basic limits relative to human exposure to electromagnetic fields in the domestic environment.

The operator must adopt the following procedures in order to reduce exposure to electromagnetic fields:

- Fasten the two welding cables as close together as possible.

- Keep head and trunk as far away as possible from the welding circuit.

- Never wind welding cables around the body.

- Avoid welding with the body within the welding circuit. Keep both cables on the same side of the body.

- Connect the welding current return cable to the piece being welded, as close as possible to the welding joint.

supply not weld while close to, sitting on or leaning against the welding machine (keep at least 50 cm away from it).

- Do not leave objects in ferromagnetic material in proximity of the welding circuit.

- Minimum distance d: 20 cm (Fig. O).

- Class A equipment:

This welding machine conforms to technical product standards for exclusive use in an industrial environment and for professional purposes. It does no assure compliance with electromagnetic compatibility in domestic dwellings and in premises directly connected to a low-voltage power supply system feeding buildings for domestic use.

EXTRA PRECAUTIONS

WELDING OPERATIONS:

- In environments with increased risk of electric shock.

- In confined spaces.

- In the presence of flammable or explosive materials.

MUST BE evaluated in advance by an "Expert supervisor" and must always be

I carried out in the presence of other people trained to intervene in emergencies.

All protective technical measures MUST be taken as provided in 7.10; cA.10 of the applicable standard EN 60974-9: Arc welding equipment. Part 9: Installation and Use".

- The operator MUST NOT BE ALLOWED to weld in raised positions unless safety platforms are used.

- VOLTAGE BETWEEN ELECTRODE HOLDERS OR TORCHES: working with more than one welding machine on a single piece or on pieces that are connected electrically may generate a dangerous accumulation of no-load voltage between two different electrode holders or torches, the value of which may reach double the allowed limit.

An expert coordinator must be designated to measuring the apparatus to determine if any risks subsist and suitable protection measures can be adopted, as foreseen by section 7.9 of the applicable standard "EN 60974-9: Arc welding equipment. Part 9: Installation and Use".

RESIDUAL RISKS

OVERTURNING: position the welding machine on a horizontal surface that is able to support the weight: otherwise (e.g. inclined or uneven floors etc.) there is danger of overturning.

- IMPROPER USE: it is hazardous to use the welding machine for any work other than that for which it was designed (e.g. de-icing mains water pipes).

- Do not use the handle to hang the welding machine.

1. INTRODUCTION AND GENERAL DESCRIPTION 2.1 INTRODUCTION

(EMF)his welding machine is a power source for arc welding, made specifically for TIG (DC) (AC/DC) welding with HF or LIFT strike and MMA welding with coated electrodes

(rutile, acid, basic).

The particular features of this welding machine (INVERTER), such as high-speed and precise adjustment, result in excellent quality welds.

The inverter system of regulation at the power supply input (primary) also leads to a drastic decrease in the volume of both the transformer and the levelling reactance so that it is possible to build a considerably smaller, lighter welding machine, highlighting its advantages of easy handling and transport.

4. DESCRIPTION OF THE WELDING MACHINE

4.1 BLOCK DIAGRAM

The welding machine consists basically of power and control modules made on PCB's and optimised to achieve perfect reliability and reduced maintenance.

This welding machine is controlled by a microprocessor that allows a large number of parameter settings so as to achieve perfect welding in any condition and with any material. However, to make the best use of its properties it is necessary to be fully aware of its possibilities.

Description (FIG. B)

1- Three-phase power supply input, rectifier unit and levelling capacitors.

2- Transistor (IGBT) switching bridge and drivers; commutes the rectified power supply voltage to high frequency alternating voltage and adjusts the power according to the required welding current/voltage.

3- High frequency transformer; the voltage converted by block 2 powers the primary winding; its function is to adjust the voltage and current to the values needed for the arc welding procedure and at the same time to form galvanic separation of the welding circuit from the power supply line.

4- Secondary rectifier bridge with levelling inductance; commutes the alternating voltage / current supplied by the secondary winding into very low ripple direct current / voltage.

5- Transistor (IGBT) switching bridge and drivers; transforms the secondary output current from DC to AC for TIG AC welding (if present).

6- Control and adjustment electronics; controls the welding current value instantaneously and compares it with the operator's setting; modulates the control impulses from the IGBT drivers that make the adjustment.

7- Welding machine operation control logic; sets the welding cycles, controls the actuators, supervises the safety systems.

8- Settings panel and display of parameters and operating modes.

9- HF strike generator (if present).

10- Protective gas solenoid valve EV (if present).

11- Welding machine cooling fan.

12- Remote control.

4.2 CONTROL, ADJUSTMENT AND CONNECTING DEVICES

2- Power cable (2 P + T (Single-phase)), (3 P + T (Three-phase)).

3- Coupler for connecting the gas hose (bottle - welding machine pressure reducer) (if present).

4- Fuse (if present).

5- Connector for water cooling unit (if present).

6- Connector for remote control:

Three different types of remote control can be connected to the welding machine using the relative 14-pole connector at the back. Each device is recognised automatically and can be used to adjust these parameters:

- Remote control with one potentiometer:

rotating the potentiometer knob varies the main current from minimum to maximum. The main current can only be adjusted with the remote control.

- Pedal remote command:

the value of the current is determined by the position of the pedal. Furthermore, in TIG 2T mode, pressing the pedal acts as a start command for the machine placed on the torch push-button (if installed).

- Remote control with two potentiometers:

the first potentiometer adjusts the main current. the second potentiometer adjusts another parameter that depends on the welding mode being used. Rotating this potentiometer displays the parameter being varied (which can no longer be controlled using the panel knob). The meaning of the second potentiometer is: ARC FORCE if in the MMA mode and END SLOPE if in the TIG mode.

- TIG torch with potentiometer.

It is obligatory to use a 5-pole torch adapter for any TIG TORCH with

an on-board adjustment potentiometer in order to protect the welding machine from internal breakage.

5. INSTALLATION

WARNING! CARRY OUT ALL INSTALLATION OPERATIONS AND ELECTRICAL CONNECTIONS WITH THE WELDING MACHINE COMPLETE SWITCHED OFF AND DISCONNECTED FROM THE POWER SUPPLY OUTLET. THE ELECTRICAL CONNECTIONS MUST BE MADE ONLY AND EXCLUSIVELY BY AUTHORISED OR QUALIFIED PERSONNEL.

5.1 PREPARATION (FIG. P)

Unpack the welding machine, assemble the separate parts contained in the package.

5.1.1 Assembling the return cable-clamp (FIG. E)

5.1.2 Assembling the welding cable-electrode holder clamp (FIG. E)

5.2 POSITION OF THE WELDING MACHINE

Choose the place to install the welding machine so that the cooling air inlets and outlets are not obstructed (forced circulation by fan, if present); at the same time make sure that conductive dusts, corrosive vapours, humidity etc. will not be sucked into the machine.

Leave at least 250mm free space around the welding machine.

WARNING! Position the welding machine on a flat surface with

sufficient carrying capacity for its weight, to prevent it from tipping or moving hazardously.

5.3 CONNECTION TO THE MAIN POWER SUPPLY

• Before making any electrical connection, make sure the rating data of the welding machine correspond to the mains voltage and frequency available at the place of installation.
• The welding machine should only be connected to a power supply system with the neutral conductor connected to earth.

- To ensure protection against indirect contact use residual current devices of the following types:

• Type A ( ) for single phase machines;

- Type B ( ) for 3-phase machines.

In order to satisfy the requirements of the EN 61000-3-11 (Flicker) standard we recommend connecting the welding machine to the interface points of the main power supply that have an impedance of less than: Zmax = 0.234 Ohm (1/N/PE 230V) 200A DC

The IEC/EN 61000-3-12 Standard does not apply to the welding machine. If the welding machine is connected to an electrical grid, the installer or user must make sure that the machine can indeed be connected (if necessary, consult the company that manages the electrical grid).

5.3.1 Plug and outlet

Connect a normalised plug (2P + P.E) (1\~); (3P + P.E) (3\~) - having sufficient capacity to the power cable and prepare a mains outlet fitted with fuses or an automatic circuit-breaker; the special earth terminal should be connected to the earth conductor (yellow-green) of the power supply line. Table (TAB.1) shows the recommended delayed fuse sizes in amps, chosen according to the max. nominal current supplied by the welding machine, and the nominal voltage of the main power supply.

WARNING! Failure to observe the above rules will make the (Class 1)

safety system installed by the manufacturer ineffective with consequent serious risks to persons (e.g. electric shock) and objects (e.g. fire).

5.4 CONNECTION OF THE WELDING CABLES

WARNING! BEFORE MAKING THE FOLLOWING CONNECTIONS MAKE SURE THE WELDING MACHINE IS SWITCHED OFF AND DISCONNECTED FROM THE POWER SUPPLY OUTLET.

Table (TAB. 1) gives the recommended values for the welding cables (in mm ^2 ) depending on the maximum current supplied by the welding machine.

5.4.1 TIG welding

Connecting the torch

- Insert the torch current cable into the appropriate quick terminal (-). Connect the three-pin connector (torch button) to the appropriate socket. Connect the torch gas pipe to the appropriate connector.

Connecting the welding current return cable

• This is connected to the piece to be welded or to the metal bench on which it rests, as close as possible to the joint being made.
  This cable is connected to the terminal with the (+) symbol.

Connecting the gas bottle

- Screw the pressure reducing valve to the gas bottle valve, first inserting the special reduction accessory supplied when argon gas is used.

- Connect the gas inflow hose to the pressure reducing valve and tighten the hose clamp supplied.

- Loosen the ringnut for adjusting the pressure reducing valve before opening the valve on the bottle.

- Open the valve on the bottle and adjust the quantity of gas (l/min) according to the suggestions for use given in the table (TAB. 4); if it is necessary to adjust the gas flow during welding this should always be done by adjusting the ring nut on the pressure reduction valve. Make sure there are no leaks in the piping and connectors.

WARNING! Always close the gas bottle valve at the end of the job.

5.4.2 MMA WELDING

Almost all coated electrodes are connected to the positive pole (+) of the power source; as an exception to the negative pole (-) for acid coated electrodes.

Connecting the electrode-holder clamp welding cable

On the end take a special terminal that is used to close the uncovered part of the electrode.

This cable is connected to the terminal with the symbol (+)

Connecting the welding current return cable

This is connected to the piece being welded or to the metal bench supporting it, as close as possible to the join being made.

This cable is connected to the terminal with the symbol (-)

Warnings:

- Turn the welding cable connectors right down into the quick connections (if present), to ensure a perfect electrical contact; otherwise the connectors themselves will overheat, resulting in their rapid deterioration and loss of efficiency.

- The welding cables should be as short as possible.

- Do not use metal structures which are not part of the workpiece to substitute the return cable of the welding current: this could jeopardise safety and result in poor welding.

6. WELDING: DESCRIPTION OF THE PROCEDURE

6.1 TIG WELDING

TIG welding is a welding procedure that exploits the heat produced by the electric arc that is struck, and maintained, between a non-consumable electrode (tungsten) and the piece to be welded. The tungsten electrode is supported by a torch suitable for transmitting the welding current to it and protecting the electrode itself and the weld pool from atmospheric oxidation, by the flow of an inert gas (usually argon: Ar 99.5) which flows out of the ceramic nozzle (FIG. G).

To achieve a good weld it is absolutely necessary to use the exact electrode diameter with the exact current, see the table (TAB. 3).

The electrode usually protrudes from the ceramic nozzle by 2-3mm, but this may reach 8mm for corner welding.

Welding is achieved by fusion of the edges of the joint. For properly prepared thin pieces (up to about 1mm) weld material is not needed (FIG. H).

For thicker pieces it is necessary to use filler rods of the same composition as the base material and with an appropriate diameter, preparing the edges correctly (FIG. I). To achieve a good weld the pieces should be carefully cleaned and free of oxidation, oil, grease, solvents etc.

6.1.1 HF and LIFT strike

HF strike:

The electric arc is struck without contact between the tungsten electrode and the piece being welded, by means of a spark generated by a high frequency device. This strike mode does not entail either tungsten inclusions in the weld pool or electrode wear and gives an easy start in all welding positions.

Procedure:

Press the torch button, bringing the tip of the electrode close to the piece (2 -3mm), wait for the arc strike transferred by the HF pulses and, when the arch has struck, form the weld pool on the piece and proceed along the joint.

If there are difficulties in striking the arc even though the presence of gas is confirmed and the HF discharges are visible, do not insist for long in subjecting the electrode to HF action, but check the integrity of the surface and the shape of the tip, dressing it on the grinding wheel if necessary. At the end of the cycle the current will fall at the

slope down setting.

LIFT strike:

The electric arc is struck by moving the tungsten electrode away from the piece to be welded. This strike mode causes less electrical-radiation disturbance and reduces tungsten inclusions and electrode wear to a minimum.

Procedure:

Place the tip of the electrode on the piece, using gentle pressure. Press the torch button right down and lift the electrode 2-3mm with a few moments' delay, thus striking the arc. Initially the welding machine supplies a current I_Lift , after a few moments the welding current setting will be supplied. At the end of the cycle the current will fall to zero at the slope down setting.

6.1.2 TIG DC welding

TIG DC welding is suitable for all low- and high-carbon steels and the heavy metals, copper, nickel, titanium and their alloys.

For TIG DC welding with the electrode to the (-) terminal the electrode with 2% thorium (red band) is usually used or else the electrode with 2% cerium (grey band).

It is necessary to sharpen the tungsten electrode axially on the grinding wheel, as shown in FIG. L, making sure that the tip is perfectly concentric to prevent arc deviation. It is important to carry out the grinding along the length of the electrode. This operation should be repeated periodically, depending on the amount of use and wear of the electrode, or when the electrode has been accidentally contaminated, oxidised or used incorrectly.

6.1.3 TIG AC welding (if installed)

This type of welding can be used to weld metals such as aluminium and magnesium, which form a protective, insulating oxide on their surface. By reversing the welding current polarity it is possible to "break" the surface layer of oxide by means of mechanism called "ionic sandblasting". The voltage on the tungsten electrode alternates between positive (EP) and negative (EN). During the EP period the oxide is removed from the surface ("cleaning" or "pickling") allowing formation of the pool. During the EN period there is maximum heat transfer to the piece, allowing welding. The possibility of varying the balance parameter in AC means that it is possible to reduce the EP current period to a minimum, allowing quicker welding.

Higher balance values give quicker welding, greater penetration, a more concentrated arc, a narrower weld pool and limited heating of the electrode. Lower values give a cleaner piece. If the balance value is too low this will widen the arc and the de-oxidised part, overheat the electrode with consequent formation of a sphere on the tip making it more difficult to strike the arc and control its direction. If the balance value is too high this will create a "dirty" weld pool with dark inclusions.

The table (TAB. 4) summarises the effects of parameter changes in AC welding. The instructions for this welding procedure are also valid.

The table (TAB. 3) shows suggested values for welding on aluminium; the most suitable electrode is a pure tungsten electrode (green band).

6.1.4 Procedure

- Use the knob to adjust the welding current to the desired value; if necessary adjust during welding to the actual required heat transfer.

- Press the torch button and make sure the gas flow from the torch is correct; if necessary, adjust pre-gas and postgas times; these times should be adjusted according to operating conditions, the postgas delay in particular should be long enough to allow the electrode and weld pool to cool at the end of welding without coming into contact with the atmosphere (oxidation and contamination).

TIG mode with 2T sequence:

- Press the torch button (P.T.) right down to strike the arc with a current of I_s . The current will increase according to the START SLOPE UP setting to the weldir current value.

- To interrupt welding, release the torch button so that either the current gradually decreases (if the FINAL SLOPE DOWN parameter has been enabled) or the arc is extinguished immediately, followed by postgas.

TIG mode with 4T sequence:

- The first time the button is pressed it will strike the arc with a current equal to I. When the button is released the current will increase according to the START SLOPE UP setting to the welding current value; this value is maintained even with the button is released. When the button is pressed again the current will decrease according to the FINAL SLOPE DOWN setting, until it reaches I_end . The I_end current will be maintained until the button is released to terminate the welding cycle and start the postgas phase. If, on the other hand, the button is released while the FINAL SLOPE DOWN function is proceeding, the welding cycle will terminate immediately and the postgas phase will start.

TIG mode with 4T and BI-LEVEL sequence:

- The first time the button is pressed it will strike the arc with a current equal to I. When the button is released the current will increase according to the START SLOPE UP setting to the welding current value; this value is maintained even when the button is released. Now, every time the button is pressed (the time between pressure and release should be short) the current will change between the setting for the BI-LEVEL I, parameter and the main current value I.

- When the button is kept pressed down for a longer space of time the current will decrease according to the FINAL SLOPE DOWN setting, until it reaches I_end . The I_end current will be maintained until the button is released to terminate the welding cycle and start the postgas phase. If, on the other hand, the button is released while the FINAL SLOPE DOWN function is proceeding, the welding cycle will terminate immediately and the postgas phase will start (FIG. M).

TIG SPOT and TIG THIN SPOT mode:

- Welding is carried out by keeping the torch push-button pressed until the pre-set time has been reached (spot time).

6.2 MMA WELDING

- It is most important that the user refers to the maker's instructions indicated on the stick electrode packaging. This will indicate the correct polarity of the stick electrode and the most suitable current.

- The welding current must be regulated according to the diameter of the electrode in use and the type of the joint to be carried out: see below the currents corresponding to various electrode diameters:

∅ Electrode (mm)	Welding current (A)
	Min. Max.
1.6 25 50
2 40 80
2.5 60 110
3.2 80 160
4 120 200
5 150 280
6 200 350

• The user must consider that, according to the electrode diameter, higher current values must be used for flat welding, whereas for vertical or overhead welds lower current values are necessary.
• As well as being determined by the chosen current intensity, the mechanical characteristics of the welded join are also determined by the other welding parameters i.e. arc length, working rate and position, electrode diameter and quality (to store the electrodes correctly, keep them in a dry place protected by their packaging or containers).
• The properties of the weld also depend on the ARC-FORCE value (dynamic behaviour) of the welding machine. The setting for this parameter can be made either on the panel or using the remote control with 2 potentiometers.
• It should be noted that high ARC-FORCE values achieve better penetration and allow welding in any position typically with basic electrodes, low ARC-FORCE values give a softer, spray-free arc typically with rutile electrodes. The welding machine is also equipped with HOT START and ANTI STICK devices to guarantee easy starts and to prevent the electrode from sticking to the piece.

6.2.1 Procedure

• Holding the mask IN FRONT OF THE FACE, strike the electrode tip on the workpiece as if you were striking a match. This is the correct strike-up method.
  WARNING: do not hit the electrode on the workpiece, this could damage the electrode and make strike-up difficult.
• As soon as arc is ignited, try to maintain a distance from the workpiece equal to the diameter of the electrode in use. Keep this distance as much constant as possible for the duration of the weld. Remember that the angle of the electrode as it advances should be of 20-30 grades.
• At the end of the weld bead, bring the end of the electrode backward, in order to fill the weld crater, quickly lift the electrode from the weld pool to extinguish the arc (CHARACTERISTICS OF THE WELD BEAD - FIG. N).

7. MAINTENANCE

• Do not put the torch or its cable on hot pieces; this would cause the insulating materials to melt, making the torch unusable after a very short time.
• Make regular checks on the gas pipe and connector seals.
• Accurately match collet and collet body with the selected electrode diameter in order to avoid overheating, bad gas diffusion and poor performance.
• At least once a day check the terminal parts of the torch for wear and make sure they are assembled correctly: nozzle, electrode, electrode-holder clamp, gas diffuser.

7.2 EXTRAORDINARY MAINTENANCE

EXTRAORDINARY MAINTENANCE MUST ONLY BE CARRIED OUT BY TECHNICIANS WHO ARE EXPERT OR QUALIFIED IN THE ELECTRIC-MECHANICAL FIELD, AND IN FULL RESPECT OF THE IEC/EN 60974-4 TECHNICAL DIRECTIVE.

WARNING! BEFORE REMOVING THE WELDING MACHINE PANELS AND WORKING INSIDE THE MACHINE MAKE SURE THE WELDING MACHINE IS SWITCHED OFF AND DISCONNECTED FROM THE MAIN POWER SUPPLY OUTLET.

If checks are made inside the welding machine while it is live, this may cause serious electric shock due to direct contact with live parts and/or injury due to direct contact with moving parts.

• Periodically, and in any case with a frequency in keeping with the utilisation and with the environment's dust conditions, inspect the inside of the welding machine and remove the dust deposited on the electronic boards with a very soft brush or with appropriate solvents.
• At the same time make sure the electrical connections are tight and check the wiring for damage to the insulation.
• At the end of these operations re-assemble the panels of the welding machine and screw the fastening screws right down.
• Never, ever carry out welding operations while the welding machine is open.
• After having carried out maintenance or repairs, restore the connections and wiring as they were before, making sure they do not come into contact with moving parts or parts that can reach high temperatures. Tie all the wires as they were before, being careful to keep the high voltage connections of the primary transformer separate from the low voltage ones of the secondary transformer. Use all the original washers and screws when closing the casing.

8. TROUBLESHOOTING

IN CASE OF UNSATISFACTORY FUNCTIONING, BEFORE SERVICING MACHINE OR REQUESTING ASSISTANCE, CARRY OUT THE FOLLOWING CHECK:

- Check that the welding current is correct for the diameter and electrode type in use.

- Check that when general switch is ON the relative lamp is ON. If this is not the case then the problem is located on the mains (cables, plugs, outlets, fuses, etc.).

• Check that the yellow led (ie. thermal protection interruption- either over or undervoltage or short circuit) is not lit.
• Check that the nominal intermittance ratio is correct. In case there is a thermal protection interruption, wait for the machine to cool down, check that the fan is working properly.
• Check the mains voltage: if the value is too high or too low the welding machine will be stopped.
• Check that there is no short-circuit at the output of the machine: if this is the case eliminate the incovenience.
• Check that all connections of the welding circuit are correct, particularly that the work clamp is well attached to the workpiece, with no interfering material or surface-coverings (ie. Paint).
• Protective gas must be of appropriate type (Argon 99.5%) and quantity.
