Stainless Steel Wire Questions
What wire do I use to MIG weld stainless steel?
ER308L is the standard wire for MIG welding 304/304L stainless steel. Use a tri-mix or 98/2 Ar/CO2 shielding gas. Do not use 75/25 Ar/CO2 as the high CO2 causes carbon pickup.
Can you TIG weld stainless with the same wire as MIG?
Yes. ER308L filler rod is used for both TIG and MIG stainless welding. The alloy composition is the same regardless of process.
Can I use carbon steel MIG wire on stainless?
No. Carbon steel wire contaminates the stainless weld and compromises corrosion resistance. Always use matching stainless filler metal (ER308L for 304/304L stainless).
