This allows for the placing of the wire feed unit close to the work area, separate from the powerbox. The following torch lead extensions are available for installation between powerbox and wire feed unit: 090 201 9472 Interconnecting Torch Lead Extension, 5 m, 50 mm2- gas-cooled 090 201 9480 Interconnecting Torch Lead Extension, 10 m, 50 mm2, gas-cooled 090 201 9499 Interconnecting Torch Lead Extension, 5 m, 50 mm2' water-cooled 090 201 9502 Interconnecting Torch Lead Extension, 10 m, 50 mm2' water-cooled 090 201 9510 Interconnecting Torch Lead Extension, 5 m, 70 mm2, water-cooled 090 201 9529 Interconnecting Torch Lead Extension, 10 m, 70 mm2, water-cooled Other lenghts available on special order. 2.4. Caster Set Option The separate wire feed unit (SDV) can be retrofitted with 4 casters (optional accessory, available at extra cost). The SDV is then easily rolled on the floor and does not need to be carried. 3 Commissioning 3.1 Transportation The MIG/MAG welding machines are equipped with rigid and swivel casters to facilitate transportation on level ground. Moving the machines on sloping ground requires additional measures to keep them safety manoeuvrable. Do not use the handles for crane hoisting. Prior to all movement of the machine the gas cylinder should be secured safely to keep it from falling off the machine. 3.2 Electrode Wire Spool Installation Place wire spool onto spool carrier so that wire runs off clockwise. The spool carrier is equipped with a brake, which can be adjusted by means of a hex. socket head cap screw. Set brake so that spool does not idle after the wire feed stops, to prevent the wire from coming loose and falling off the spool. 23 Loosen starknob screws and open gear brackets. The feed rollers are factory installed for use with 1.2/1.6 mm 0 wire (for 0.6/0.8 mm 0 wire the feed rollers must be reversed on the shaft). Insert deburred wire into spiral guide tube, place over first feed roller into guide tube of bracket, then across second feed roller into the Euro-connector. Close gear brackets and tighten starknob screws, setting just slightly more pressure to the feed roller feeding into the Euroconnector, to ensure a smooth wire feed. Failure to observe will not give a smooth wire feed. Remove gas shroud by turning clockwise, and contact tip by turning counter-clockwise. Set mains switch (6) to ON and activate the touch control switch (12) to run the wire through the torch lead until it protrudes approximately 2 cms from the swan neck. Reinstall contact tip and gas shroud. Please note that the welding machine is factory set for use with 1.2 mm 0 wire. If a different wire diameter is used the steel liner and contact tip have to be changed to match the wire diameter. 3.3 Power Supply This welding power source is suitable for operation on the supply voltage shown on the name plate. A power supply cable is fitted to the machine, the phase-sequence does not matter and has no influence on the direction of rotation of the cooling fan and, if present, a coolant plump. Caution: on water-cooled units the refrigerating unit must be filled with coolant (mixture of water and antifreeze) prior to commissioning. 3.4 Earth Cable Connect earth cable plug to Earth Cable Socket (6) on the machine's front panel. Use only genuine Elektra parts with recommended cross sections. Structural components, beams, pipes or rails should not be used for earth conduction, if they are not the actual workpiece. When using welding tables or jigs ensure proper conducting. 3.5 Shielding Gas Supply Ensure the gas cylinder's valve cap is always securely in place before transportation. Risk of personal injury if the gas cylinder valve is damaged! Place gas cylinder onto the cylinder rack and secure with chain. Open valve briefly to clear any foreign matter from it before installing the pressure regulator. ( Caution: Risk of personal injury by the pressurized gas. ) 3.5.1 Gas Flow Setting The correct amount of shielding gas, and a steady gas flow at the welding seam, are essential to provide sufficient shielding of the weld pool. Insufficient shielding causes porous welding seams. 24 Rule of thumb to calculate the required shielding gas flow rate: Amount of gas in Itr/min = 10 x the electrode wire diameter in mm Example: Wire diameter 1.0 mm requires a gas flow rate of 10 Itr/min.

After selecting the electrode wire used (8) and the desired welding current (1), a single-chip microprocessor automatically sets the optimal wire feed speed and welding voltage. The root or weld penetration can be corrected by setting the welding voltage pot (2) as required. More penetration - higher welding voltage Less penetration - lo...
