Welding Gas For Stainless Steel. Therefore the recommended shielding gas to use for short circuit stainless steel MIG welding is a tri-mix shielding gas such as 90He75Ar25CO2. The gas contains an active component H 2 which brings down the oxygen level in the weld area.
Short-circuit metal transfer mode for welding thin material and spray arc transfer mode with thicker material. It produces a stable welding arc and is suitable for all grades of stainless steel. Ad Overhead Ambient or Portable.
In some cases there is tri-mix shielding gas containing 90 Helium 75 Argon and 25Carbon dioxide.
It employs two modes ie. Ive welded many different kinds of stainless Tig Argon and MigFor my money best apearance and penetration with mig is a trimix gas buy a small bottle its very expensive and not nessasary for mild steel just wasting money. Ad Find China Manufacturers Of Welding Wire. The gas contains an active component H 2 which brings down the oxygen level in the weld area.
