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 spatter; a smooth weld bead will be difficult to obtain.
Avoid unnecessary gas loss by closing the tank valve when finished welding.
viii. Gas Selection
Different materials require different shielding gases when MIG welding (refer
to the set-up LCD window).
Mild Steel: Use 75% Argon and 25% CO2 for reduced spatter and reduced
penetration for thinner materials. DO NOT USE Argon gas concentrations
higher than 75% on steel. The result will be extremely poor penetration,
porosity, and brittleness of weld.
Mild Steel: Use CO2 for deeper penetration but increased spatter. (A CO2
regulator adapter will be needed.)
Stainless Steel: Use a mixed gas consisting of Helium, Argon, and CO2.
Aluminum or Bronze: Use 100% Argon.
