4. Operation
Before starting any welding activity ensure that you have suitable eye protection and protective
clothing. Also take the necessary steps to protect any persons within the area.
Wire types and sizes
Use the correct wire type for the base metal being welded. Use stainless steel wire for stainless steel, alumi-
num for aluminum and steel wires for steel.
Use a smaller diameter wire for thin base metals. For thicker materials use a larger wire diameter and larger
machine, check the recommended welding capability of your machine. As a guide refer to the “Welding
Wire Thickness Chart” below.

depending on the amperage capability of your machine.
