MIG/FLUX-CORE WIRE FEED WELDER KIT 058-8195-2
Gas hoses, regulator and gas cylinder connections
• Connect the gas hose to the gas solenoid valve on the back panel of the welder.
• Connect the other end to the regulator connected to the shielding gas cylinder.
• Slowly open the cylinder valve by turning it counterclockwise until the cylinder pressure gauge
fixes the cylinder pressure.
• Slowly turn the adjustment knob clockwise to increase gas flow to 20 cfm. Turn it
counterclockwise to reduce the gas flow.
• Gas flow can be heard at the end of the gun when the trigger is activated.
Note: If there is no gas flow, harsh arc with excessive spatter will be found and a smooth weld bead
will not be obtained.
Gas selection
Different materials require different shielding gas when MIG welding. Refer to the set up chart inside
the wire drive compartment.
Mild steel: Use 75% Argon and 25% for reduced spatter and reduced penetration for thinner
materials. Use CO
2
for deeper penetration and increased spatter.
Note: Do not use argon gas concentrations higher than 75% on steel. The result will be extremely
poor penetration, porosity, and brittleness of weld.
Stainless steel: Use a mixed gas consisting of Helium, Argon, and CO
2
.
Aluminum or bronze: Use 100% Argon feed compartment.
