I have a crazy setup that I build my stuff in. I have a mig out by my car and a tig in the basement. I bought a roll of 308 wire for my mig to tack my header tubes. I then planned to do the finish welding with my tig. I don’t plan to change my mig gas from argon/co2. Am I going to have a problem with the tack welds when I tig? It seems mig tack welds on mild steel seem to have some sort of contamination the tig doesn’t like, not sure about the stainless. Or is this a good old fashioned case of overthinking ???
Thanks
