MIG/MAG

The welding equipment for manual arc welding with automatic wire feed allows the joining of metal parts through a melting process of the edges to be joined and the filler metal. Melting is caused by the arc, which is formed between the material to be welded and the metal wire continuously emerging from the end of the burner. Metal wire serves as a filler material for the connection of the parts. Higher welding current allows welding of bigger plates. For damages resulting from failure to comply with these instructions, no liability is accepted.

The tungsten inert gas welding technology (TIG welding) comes from the U.S., where it became known in 1936 as argon welding. Only after the second World War II was it introduced in Germany. In English-speaking countries this method is called TIG, after the English word for tungsten. The method offers several interesting advantages over other fusion welding processes. For example, it is universally applicable: if a metallic material is at all suitable for welding, then it can be processed with this procedure. Additionally it is also a very „clean“ process, which produces very little pollution and little splashes and, when used correctly, guarantees a high quality welded joint. A particular advantage of TIG welding is also the fact that compared to other methods employing a consumable electrode, the addition of a filler material and the current are not linked.

Therefore the welder has control over the power:

• it may be optimally matched to the welding task and it is only necessary to add as much filler as is currently required. This makes the process particularly suitable for welding root passes and for welding in forced positions.
• due to the relatively low and small-scale heat input there is little tendency for the workpieces to warp during welding.
  • these advantages have caused the process to be particularly suitable for welding of air planes and space vehicles, construction elements used in nuclear installations and installation components and equipment for chemical plants.

MMA

MANUAL ARC WELDING

Manual arc welding, briefly called MMA (Manual Metal Arc Welding), is one of the oldest electric welding procedures used for metallic materials, which is still used today. In 1891 Nikolai Gavrilovich Slawjanow replaced the carbon electrodes commonly used in his time for arc welding by a metal rod that was both the arc carrier and filler metal. Since the first rod electrodes were not coated, the weld itself was not protected from oxidation. Therefore these electrodes were difficult to weld. The electric arc burning between an electrode and the workpiece is used as the heat source for welding.

The high temperature of the arc melts the material in the welding area. The rod electrode simultaneously melts off acting as a filler material to form the weld bead. Both AC and DC currents can be used to power the process. Rod electrodes are used as filler material in arc welding. For each welding type there are appropriate electrodes, e.g. for build-up welding and joint welding. Information concerning the nature, characteristics and application of an electrode is provided by the brief label, which is printed on each electrode package. The gases produced by the melting of the electrode coating are used to stabilise the arc and separate the liquid metal transfer in the arc from the influences of the surrounding air and to reduce the burning of alloy components. Apart from that the melted coating also produces slag. This liquid is lighter than liquid steel and is washed onto the weld. This enables a slow cooling process and thus lower shrinkage stress. The anode (positive pole) is heated by electron bombardment and positive metal ions flow from there to the workpiece. Therefore consumable electrodes are mostly used as anodes with the workpiece material acting as a negative pole. In TIG welding the electrode has a negative pole in order to keep the degree of removal low. Arc welding is used in the construction industry (bridge supports) but also in precision engineering. The following rule applies regardless of application: The thinner the material, the more expensive the equipment. Due to low current levels (necessary not to burn through materials under 1 mm wall thickness), a significantly more complex control process is required.

GENERAL SAFETY

If you have doubts on connecting and operating with this device, please contact the manufacturer. The user must read this manual carefully before first use of the device.

DUTY CYCLE

Duty cycle is a welding equipment specification which defines the number of minutes, within a 10 minute period, during which a given welder can safely produce a particular welding current. For example, a 200 amp welder with a 60% duty cycle must be „rested“ for at least 4 minutes after 6 minutes of continuous welding with 200 amp..

WORK AREA PRECAUTIONS

• Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep bystanders, children, and visitors away while operating a power tool. Dis-tractions can cause you to lose control. Protect others in the work area from debris such as chips and sparks. Provide barriers or shields as needed.

ELECTRICAL SAFETY

• Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adapter plugs. Check with a qualified electrician if you are in doubt whether the outlet is properly grounded. If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user.
• Double insulated tools are equipped with a polarized plug (one blade is wi der than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double insulation eliminates the need for the three wire grounded power cord and grounded power supply system.
• Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is grounded.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• Do not abuse the Power Cord. Never use the Power Cord to carry the tool or pull the Plug from an outlet. Keep the Power Cord away from heat, oil, sharp edges, or moving parts. Replace damaged Power Cords immediately. Damaged Power Cords increase the risk of electric shock.
• When operating a power tool outside, sue an outdoor extension cord mar- ker "WA" or "W". These extension cords are rated for outdoor use, and reduce the risk of electric shock.

PERSONAL SAFETY

• Stay alert. Watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.
• Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
• Avoid accidental staring. Be sure the Power Switch is off before plugging in. Carrying power tools with your finger on the Power Switch, or plugging in power tools with the Power Switch on, invites accidents.
• Remove adjusting keys or wrenches before turning the power tool on. A wrench or a key that is left attached to a rotating part of the power tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the power tool in unexpected situations.
• Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

TOOL USE AND CARE

• Use clamps (not included) or other practical ways to secure and support the workpiece to a stable platform. Holding the work piece by hand ro against your body is unstable and may lead to loss of control.
• Do not force the tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed.
• Do not use the power tool if the Power Switch does not turn it on or off. Any tool that cannot be controlled with the Power Switch is dangerous and must be replaced.
• Disconnect the Power Cord Plug from the power source before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.
• Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.
• Maintain tools with care. Keep cutting tools maintained and clean. Properly maintained tools are less likely to bind and are easier to control. Do not use a damaged tool. Tag damaged tools "Do not use" until repaired
• Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool's operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.
• Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool may become hazardous when used on another tool.

SERVICE

• Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.

- When servicing a tool, use only identical replacement parts. Use of unauthorized parts or failure to follow maintenance instructions may create a risk of electric shock or injury.

SPECIFIC SAFETY RULES

The TIG-welding is very sensitive about the surface (which is to be welded) contamination. For this reason, before welding you have to remove rests of paints and greases as well as the oxidized layer from the surface which will be welded.

DCTIG-welding

• Connect the gas hose to the gas to welder supply socket.
• Connect the gas hose to the welding gun and to the argon supply (to the gun) socket.
• Connect weld piece to the mass clamp in welder, outlet (+).
• Connect the welding handle plug to the arc and argon control rod.

Gas test: Check the connection of the electric supply and switch on the voltage.

Open the valve (regulator) of bottle with argon and switch on flow meter. Gun switch-key has to be pressed and you have to select an appropriate gas flow. The inflow switch-key has to be released and the gas inflow

will be automatically stopped after several seconds. In case of using the high frequency ignition, the wolframic electrode has to be retracted 2-3 mm from the weld piece. Next, after switching on the switch-key, the arc will be triggered. The switch off will result in the reduction of electric current intensity and the arc will no longer be active. The blowing shaft can not decay before the electric arc switch off. Gas must cool down the fusion weld as it will not become oxidized. After finishing the welding process, you have to switch off the argon supply button on the bottle and the welder supply. Pulling the electric supply plug when the electric supply switch is on is prohibited.

Manual welding with the electrode

• Connect the E-Hand conduit to the negative pole (-).
• Set the current intensity regulator at the proper intensity (the impulse current intensity regulator is in lower position). Select current in accordance with empirical formula: l = 40d , where d is the electrode diameter.
  • Positive and negative connection during the welding process.
• The welder has to be connected to the electric supply socket and turn main switch on. The control lamp will light.
• It is necessary to bring the attention to the relative intensity of welding current and the relative welder's make-time.
  • The overloading may result in damages. You can avoid this.
• After finishing the device operation, it is necessary to leave the device for cooling and then – switch off the supply.

MIG/MAG welding

Please install the items in the order shown. Pay attention to the proper arrangement of the elements as shown in the pictures. The device is not operational yet. Open the gas flow at a pressure of 5-7 l/min. Protect the gas outlet against gusts of wind. Also note the following: The first stages of the current controller are used for welding thin metal sheets and the next stages are used for thicker walls. With each operation of the switch the wire feed speed should also be adjusted. If a drop is formed at the end of the welding wire while welding, the wire feed speed has to be increased; however if it can be felt as the wire presses against the hose bundle, the speed has to be reduced. Always use tongs to move the parts that have just been welded and to remove encrustations at the end of the burner, as these elements are very hot. Once the arc is ignited keep the hose bundle at an angle of about 30 degrees vertically.

WEEKLY MAINTENANCE

Check if the room ventilation works properly.
