I'm still more of a lurker at this point. I have a bit of experience with MIG, stick and oxy/acetylene. I'm watching for a good time to get a TIG machine to add to the group. This would be my first departure from Miller/Hobart. Currently I have a Miller 210, 130XL, Blue Star 6000, and Hobart StickMate XL (AC/DC).
I want to get into TIG next. Whether I start with an AC/DC machine or DC, I'm still mulling over.
I'll take the leap before long. Until then, I'll be lurking around the forums.
