Select the appropriate shielding gas in accordance to material being welded and wire being used. The table below can
give you some useful indications:
METAL GAS NOTE
Mild Steel CO2
Argon + CO2
Argon + CO2 + Oxygen
Argon controls spatter
Oxygen improves arc stability
Stainless Steel Argon + CO2 + Oxygen
Argon + Oxygen
Arc stability.
Minimum splatter
METAL GAS NOTE
Copper, Nickel & Alloys Argon
Argon + Helium
Suitable for light gauges because of low flowability
of the weld pool.
Higher heat input suitable for heavy sections
Use Spool Gun for MIG
NOTE: THIS MACHINE IS NOT AN APPROPRIATE POWER SOURCE FOR WELDING
ALUMINUM.
• Press the PROCESS SELECTOR BUTTON on the front panel to the top position.
• Connect the MIG gun into the EURO CONNECT SOCKET.
• Connect the MIG ELECTRODE POLARITY JUMPER (8) to the appropriate DINSE SOCKET:
o Flux-cored wire welding (FCAW): Jumper to NEGATIVE (-) DINSE SOCKET.
o MIG Welding (GMAW): Jumper to POSITIVE (+) DINSE SOCKET.
• Connect the ground cable to the appropriate DINSE SOCKET:
o Flux-cored wire welding (FCAW): Ground cable to POSITIVE (+) DINSE SOCKET.
o MIG Welding (GMAW): Ground cable to NEGATIVE (-) DINSE SOCKET.
• Ensure the ground clamp has a good connection to the workpiece and is connected on clean, bare metal (not rusty or
painted).
• Load the spool of wire inside the cabinet and feed it through the WIRE FEEDER into the gun (see “Installing the
Welding Wire”, page 14).
• Switch the unit ON with the ON/OFF SWITCH.
• Press the gun trigger to load the wire through the gun.
• Set the welding parameters:
1. Adjust wire feed speed with the RIGHT KNOB.
2. Adjust arc voltage with the LEFT KNOB.
• (GMAW only) Turn on the gas cylinder, pull the trigger to check for gas flow and adjust the flow rate.
• Bring the gun close to the workpiece and press the trigger.
