Operating Instructions and Parts Manual
MIG/STICK WELDER

-Do not touch cylinder with MIG gun.
-Do not weld on the cylinder.
-Always secure cylinder upright to a cart or stationary object.
-Keep cylinders away from welding or electrical circuits.
-Use the proper regulators, gas hose and fittings for the specific
application.
When MIG (solid) wires are used, the shielding gas is required.
6.1. Polarity changing:
The factory polarity setting is for flux core
welding (no shielding gas is required). At
this mode, the MIG gun lead is connect to
“-” (negative) polarity and ground cable
end is to “+” (positive). If MIG welding
with shielding gas the MIG gun lead is to
“+”, and ground cable is connected to “-”.
Secure leads tight with fasteners. See
illustrations below.
6.2. The gas hose, regulator and gas cylinder connection
Attach one end of the gas hose to the gas solenoid valve (gas inlet) located on
the back panel of the welder. Attach the other end to the gas regulator which is
attached to the shielding gas cylinder. See illustration below

NOTE:
Slowly open the cylinder valve by turning it counterclockwise until the cylinder
pressure gauge registers on the first gauge of the regulator. Turn the adjustment
knob clockwise (right) slowly to increase gas flow to 20 cfm. To reduce the gas
flow turn the adjustment counterclockwise (left). The gas valve is located on the
back panel of the welder and activated by the trigger. Gas flow should be heard
when the trigger is activated. No gas flow will result in a harsh arc with excessive
