EXPOSURE TO A WELDING ARC IS EXTREMELY HARMFUL TO THE EYES AND SKIN. PROLONGED EXPOSURE TO
A WELDING ARC CAN CAUSE BLINDNESS AND BURNS. NEVER STRIKE AN ARC OR BEGIN WELDING UNLESS
YOU ARE ADEQUATELY PROTECTED. WEAR FIRE RESISTANT WELDING GLOVES, HEAVY LONG SLEEVED SHIRT,
CUFFLESS PANTS; HIGH TOPPED SHOES AND A WELDING HELMET.

Welding Wire Selection

This welder can work with solid steel wire from .023"~.035" (0.6~0.9mm) diameter (MIG welding, "GMAW") and with .023"~.035"
(0.6~0.9mm) diameter flux-cored wire (flux-cored wire welding, "FCAW").

Gas Selection

Select the appropriate shielding gas in accordance to material being welded and wire being used. The table below can give you
some useful indications:

Setup for MIG (GMAW) & Flux-Cored Wire (FCAW) Welding
Press the PROCESS SELECTOR BUTTON on the front panel.
Ÿ
Connect the MIG gun into the EURO CONNECT SOCKET.
Ÿ
Connect the Wire Drive Polarity Lead(10) to the appropriate DINSE SOCKET:
Ÿ
1. Flux-cored wire welding (FCAW): Connected to NEGATIVE (-) DINSE SOCKET.
2. MIG Welding (GMAW): Connected to POSITIVE (+) DINSE SOCKET.
Connect the ground cable to the appropriate DINSE SOCKET:
Ÿ
1. Flux-cored wire welding (FCAW): Ground cable to POSITIVE (+) DINSE SOCKET.
2. 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
Ÿ
painted).
Load the spool of wire inside the cabinet and feed it through the WIRE FEEDER into the gun (see "Installing the Welding
Ÿ
Wire", page 10).
Switch the unit ON with the ON/OFF SWITCH.
Ÿ
Press the gun trigger or wire feed button (6) to load the wire through the gun.
Ÿ
Set the welding parameters:
Ÿ
1. Adjust the output current.
Press selector button (1) to select output current, adjust the current with adjustment knob, wire feed speed & arc
voltage match automatically.
2. Press selector button (1) to select voltage modifying, adjust the voltage from -10~+10 with adjustment knob, modify
voltage based on type of material and thickness being welded.
3. Press selector button (1) to select inductance, adjust the inductance from -10~+10 with adjustment knob, The
effects of the inductance can help reduce spatter, produce a "softer" arc and help wetting out. There is a wetting-
out/softness trade off against penetration/stiff/arc-force/dig qualities.
(GMAW only) Turn on the gas cylinder, pull the trigger or press gas checking button to check for gas flow and adjust the
Ÿ
flow rate.
Bring the gun close to the workpiece and press the trigger.
