5 WELDING
5.1 Installation
Make sure that the wire diameter corresponds to the diam-
eter indicated on the wire feeder roller, and that the selected
program is compatible with the material and type of gas. Use
wire feeder rollers with a "U"-shaped groove for aluminum
wires, and with a "V"-shaped groove for other wires.
5.2 THE MACHINE IS READY TO WELD
• Connect the earth clamp to the workpiece.
• Set the switch Q to 1.
• Remove the gas nozzle.
• Unscrew the contact tip.
• Insert the wire in the wire liner of the torch, making sure that
it is inside the roller groove and that the roller is in the correct
position.
• Press the torch trigger to move the wire forward until it
comes out of the torch.
• Caution: keep your face away from the gun tube
assembly while the wire is coming out.
• Screw the contact tip back on, making sure that the hole
diameter is the same as that of the wire used.
• Assemble the gas nozzle.
5.3 WELDING CARBON STEELS WITH GAS
PROTECTION.
In order to weld these materials you must:
• Use a welding gas with a binary composition, usually
ARGON + CO2 with percentages of Argon ranging from
75% up. With this blend, the welding bead will be well joint-
ed and attractive.
Using pure CO2 as a protection gas will produce narrow
beads, with greater penetration but a considerably increase
