Best Gas for TIG Welding Carbon Steel
There is one situation when helium or a helium-argon mix makes sense for welding carbon steel: welding very thick material. The general rule is that you can TIG weld one-thousandth of an inch (.001) per amp. A 150-amp welder is suitable for 0.15-inch thick material, or about 5/32. A 250-amp welder can weld quarter-inch steel.

How To MIG Weld Aluminum, A Home Welder Tips For Success
Argon gas (or Argon Helium mix) is the shielding gas. Spray transfer means the tip of the wire never goes into the weld puddle. It is important to understand this as this is different to welding mild steel and to allow this process to happen you need to retain the correct distance (approx 1/8th inch) from the weld puddle. ...
