Anybody have experience with TIG welding? I have and have used a MIG for many years, but find it frustrating at times for sheet metal. I'm looking at a Hobart A/C D/C stick/TIG machine. My hopes were that I could perform neater welds to sheet metal without the spatter and grinding. Again I have done alot with the MIG and know the tricks to reduce warpage. Its time to replace my MIG and wondered if there was something better.
