USER MANUAL TW821075 Telwin

CONTINUOUS WIRE WELDING MACHINE FOR MIG/MAG AND FLUX ARC WELDING DESIGNED FOR INDUSTRIAL AND PROFESSIONAL USE.

Note: In the following text the term "welding machine" will be used.

1. GENERAL SAFETY CONSIDERATIONS FOR ARC WELDING

The operator should be properly trained to use the welding machine safely 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: A welding equipment. Part 9: Installation and Use).

• Avoid direct contact with the welding circuit: the no-voltage supplied by the welding machine can be dangerous under certain circumstances.
• When the welding cables are being connected or ch and repairs are 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 supply 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 earth 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 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, concentration and the length of exposure itself.
• Keep the gas bottle (if used) away from heat sources, including direct sunlight.

- Make sure there is adequate electrical insulation with respect to the torch, the workpiece and any (accessible) earthed metal parts in the vicinity.

This is normally achieved by wearing gloves, shoes, head coverings and clothing designed for this purpose and by using insulating platforms 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 UN EN 11611) and welding gloves (compliant with UNI EN 12477) without exposing the skin to the ultraviolet and infrared rays produced by the arc; the protection must extend to other people who are near the arc by way of screens or non-

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 (EMF) around the welding circuit.

Electromagnetic fields can interfere with certain medical equipment (e.g. Pace-makers, 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.

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

- Never wind welding cables around the body.

ks 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.
• Do 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. M).

- Class A equipment:

This welding machine conforms to technical product standards for exclusive use in an industrial environment and for professional purposes. It does not assure compliance with electromagnetic compatibility in domestic dwellings and in premises directly connected to a low-voltage power suppl system feeding buildings for domestic use.

EXTRA PRECAUTIONS

- WELDING OPERATIONS:

• In environments with increased risk of electric shock;
• In confined spaces;
  of In the presence of flammable or explosive materials; MUST BE evaluated in advance by an "Expert supervisor" and must always be 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; A.8; A.10 of the applicable standard E 60974-9: Arc welding equipment. Part 9: Installation and Use".

• Welding MUST NOT be allowed if the welding machine or wire feeder is supported by the operator (e.g. using belts).
• The operator MUST NOT BE ALLOWED to weld in raised positions unless safety platforms are used.

- VOLTAGE BETWEEN ELECTRODE HOLDERS OR TORCHES: ad working with more than one welding machine on a single piece y 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 UNI the apparatus to determine if any risks subsist and suitable protection measures can be adopted, as foreseen by section red 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 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).
• MOVING THE WELDING MACHINE: Always secure the bottle, taking suitable precautions so that it cannot fall accidentally (if used).

The safety guards and moving parts of the covering of welding machine and of the wire feeder should be in their proper positions before connecting the welding machine to the power supply.

WARNING! Any manual operation carried out on the mov parts of the wire feeder, for example:

• Replacing rollers and/or the wire guide;
• Inserting wire in the rollers;
• Loading the wire reel;
• Cleaning the rollers, the gears and the area underneath them;
• Lubricating the gears.

SHOULD BE CARRIED OUT WITH THE WELDING MACHINE SWITCHED OFF AND DISCONNECTED FROM THE POWER SUPPLY OUTLET.

LOADING THE WIRE REEL (Fig. H)

WARNING! BEFORE STARTING THE OPERATIONS

TO LOAD THE WIRE MAKE SURE THE WELDING MACHINE IS SWITCHED OFF AND DISCONNECTED FROM THE MAIN POWER SUPPLY OUTLET.

MAKE SURE THAT THE WIRE FEEDER ROLLERS, THE WIRE GUIDE HOSE AND THE CONTACT TIP OF THE TORCH MATCH THE DIAMETER AND TYPE OF WIRE TO BE USED AND MAKE SURE THAT THESE ARE FITTED CORRECTLY. WHEN INSERTING AND THREADING THE WIRE DO NOT WEAR PROTECTIVE GLOVES.

• Open the reel compartment door.
• Position the wire reel on the spindle, holding the end of the wire upwards; make sure the tab for pulling the spindle is correctly seated in its hole (1a).
• Release the pressure counter-roller(s) and move them away from the lower roller(s) (2a-b);
• Make sure that the towing roller(s) is suited to the wire used (2c).
• Free the end of the wire and remove the distorted end with a clean cut and no burr; turn the reel anti-clockwise and thread the end of the wire into the wire-guide infeed, pushing it 50-100mm into the wire guide of the torch fitting (2d).

• Re-position the counter-roller(s), adjusting the pressure to an 1)intermediate value, and make sure that the wire is correctly positioned in the groove of the lower roller(s) (3)

• Use the adjustment screw located at the centre of the spindle to apply a slight braking pressure on the spindle itself (1b).

• Remove the nozzle and contact tip (4a).
• Insert the welding machine plug in the power supply outlet, switch on the welding machine, press the torch button and wait for the end of the wire to pass through the whole of the wire guide hose and protrude by 10-15 cm from the front part of the torch, release the button.

WARNING! During these operations the wire is live and

subject to mechanical stress; therefore if adequate precautions are not taken the wire could cause hazardous electric shock, injury and striking of electric arcs:

- Do not direct the mouthpiece of the torch towards parts of the body.

• Keep the torch away from the gas bottle.
• Re-fit the contact tip and the nozzle onto the torch (4b).
• Check that wire feed is regular; set the roller and spindle braking pressure to the minimum possible values making sure that the wire does not slide in the groove and when feed is halted the loops of wire are not loosened by excessive reel inertia.
• Cut the end of the wire so that 10-15 mm protrude from the nozzle.
• Close the reel compartment door.

6. WELDING: DESCRIPTION OF THE PROCEDURE

• Connect the return cable to the piece to be welded.

• 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;
• Every time the wire reel is changed, blow out the wire-guide hose using dry compressed air (max. 5 bar) to make sure it is not damaged;
• Before every use, check the wear and correct assembly of the parts at the end of the torch: nozzle, contact tip, gas diffuser.
• Make frequent checks on the state of wear of the wire feeder rollers, regularly remove the metal dust deposited in the feeder area (rollers and wire-guide infeed and outfeed).

Wire feeder

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.

• Inspect the welding machine regularly, with a frequency depending on use and the dustiness of the environment, and remove the dust deposited on the transformer, reactance and rectifier using a jet of dry compressed air (max. 10 bar).
• Do not direct the jet of compressed air on the electronic boards; these can be cleaned with a very soft brush or suitable 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.
