OPERATING MANUAL
11.8 Wire Types and Sizes
Use the correct wire type for the base metal being welded. Use stainless steel wire for stainless steel, aluminium wires for
aluminium and steel wires for steel.
Using poor quality milled wire can result in poor performance and appearance. To ensure optimal performance
when welding, use standards approved wire.
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.
11.9 Gas Selection
The purpose of the gas in the MIG process is to shield the wire, the arc and the molten weld metal from the atmosphere.
Most metals when heated to a molten state will react with the air in the atmosphere, without the protection of the shielding
gas the weld produced would contain defects like porosity, lack of fusion and slag inclusions. Additionally, some of the gas
becomes ionised (electrically charged) and helps the current flow smoothly.
The correct gas flow is critical in protecting the welding zone from the atmosphere.
Too low a flow will give inadequate coverage and result in weld defects and unstable arc conditions.
Too high a flow can cause air to be drawn into the gas column and contaminate the weld zone.
Use the correct shielding gas. CO2 is suitable for steel and offers good penetration characteristics; the weld profile is
narrower and slightly more raised than the weld profile obtained from Argon CO2 mixed gas. Argon CO2 mix gas offers
better weldability for thin metals and has a wider range of setting tolerance on the machine. Argon 5/2 is a good all-round
mix suitable for most applications.
