• Unpack the welder;
• Assemble the plastic handle on torch wrap using the screws provided.
• Attach the standard MIG welding torch to the threaded connection on the front of the welder.
• To connect the spool gun, connect the spool gun cable to the threaded fitting on the front of the
welder and also connect the seven pin cannon type plug to the connector on the front of the
welder.
WARNING: Cylinders are highly pressurized. Handle with care. Serious accidents
can result from improper handling or misuse of compresses gas cylinders. Do not
drop the cylinder, knock it over, expose it to excessive heat, flames or sparks. Do not
strike it against other cylinders.
The gas cylinder (not supplied) should be fixed firmly to the work bench or to the wall in a way
that it can’t fall.
• INSTALLING THE GAS REGULATOR: Insure that the pressure regulator valve is fully closed
by turning the valve handle counter clockwise. Connect the regulator to the gas cylinder by
threading the large nut on the regulator onto the mating fitting on the gas cylinder, tighten
firmly.
• Connect the gas hose to the regulator.
• Completely open the cylinder valve, then set the gas flow to approx. 20-30 CFH by turning
the pressure regulator valve clockwise.
• Release the pressure on the wire feed roll by flipping down the pressure adjust knob (A) Fig.5,
page 19. Then turn the welder on and press the torch trigger to insure that gas is flowing
through the torch.
Metal GAS NOTE
Mild Steel CO2
Argon + CO2
Argon + CO2 + Oxygen
Argon controls spatter
Oxygen improves arc stability
Aluminium Argon
Argon + Helium
Arc stability, good fusion and minimum splatter.
Higher heat input suitable for heavy sections.
Minimum porosity.
Stainless Steel Argon + CO2 + Oxygen
Argon + Oxygen
Arc stability.
Minimum splatter.
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.
