My OLD Lincoln Tombstone finally gave up the ghost. I'm tired of messing with it, need to buy something new, and I'm looking for suggestions. Most of my welding is on broken farm equipment or in fabricating implements/things I'm too cheap to buy or can't buy. Typically I only use stick on heavy/thick steel. On anything 3/8" or below, I'll usually use flux core if it's plain steel and MIG for anything else. I use a spool gun for aluminum. I have read a lot about the new inverter welders that can also do TIG which I learned about 35 years ago as heliarc. It was great for exotics but I'm not sure what I would do with it now. Please educate me. My inclination was to just get a Lincoln AC/DC-225 which I would just leave on DC but I'm not sure what I would be missing. Portability is not really an issue. All my fields are reasonably close and I've got a little 120V 100 amp wire feed that I can run on a generator to tack stuff together before I drag it back to the shop. So here are my questions:
1) What is the real difference between stick welding, using DC on a tombstone or one of the new inverter machines? I don't think I have any real arc control issues, so what am I missing?
2)What could I use TIG for that I can't already do with MIG?
Thanks!
