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.
MIG, MAG, Aluminum Welding (14) This welder can work with solid steel wire from .023"~.035" (0.6~0.9mm) diameter (MIG weld-
ing, “GMAW”) and with .023"~.035" (0.6~0.9mm) diameter flux-cored wire (flux-cored wire welding, “FCAW”), with .023"~.035"
stainless steel wire, with .035"~.045" (0.9~1.2mm) Silicon and Magnesium Aluminum wire.
Note: Only .035" wire available in Synergic Gasless MIG Welding.

Ÿ
Connect the MIG gun into the EURO CONNECT SOCKET.
Ÿ
Connect the Wire Drive Polarity Lead (9) to the POSITIVE (+) SOCKET.
Ÿ
Connect the work clamp to the NEGATIVE (-) SOCKET.
Ÿ
Ensure the work clamp has a good connection to the workpiece and is connected on clean, bare metal (not rusty or painted).
Ÿ
Load the spool of wire inside the cabinet and feed it through the WIRE FEEDER into the gun (see “Installing the Welding Wire”,
page 10).
Ÿ Connect the gas line to the regulator and connect to the gas cylinder.
Ÿ
Press the gun trigger or inching button (5) to load the wire through the gun.
Ÿ Turn on the gas cylinder, pull the trigger to check for gas flow and set the flow rate to between 20~30 CFH.
Ÿ
Turn the power source on and select the MIG function with the Manual MIG/Synergic MIG/Lift TIG/Stick selector switch.
Ÿ Set the welding parameters.
Ÿ
Bring the gun close to the workpiece and press the trigger to start welding.
