New member here, though I've lurked for a few weeks. It's been more than a few years since I've welded, stick and MIG only, and I'd like to get back into it.
Like my username says, I'm a metallurgical engineer. I make a decent living scrutinizing material properties, reviewing/approving WPSs and PQRs, pondering weld arc and puddle physics, conducting all kinds of weld testing, and a bunch of other stuff that's very interesting but nowhere near as fun as actually welding. My head's full of plenty of great theory, but I dearly miss the hands-on element.
SO, I'm going to get back into welding (not that I was ever that great at it), which means I get to shop for welding equipment! I'm looking for a little advice/opinions on what machine to get. Let me decribe what I THINK I want:
- I love stick welding so I want GOOD stick welding capability
- I'd also like to learn TIG. I don't have any particular projects in mind right now but I can see it coming in handy for occasional sheet metal work, and besides, I think it'd just be fun to learn.
- I figure I'll mostly weld carbon steel and some austenitic stainless ocassionally. I don't plan on any aluminum welding, but maybe that's short sighted?
- 6010 capability would be nice but isn't absolutely essential for me. Most of my welding will likely be 7014/7018 for CS and 308/309 for SS.
There's no doubt that the PA200 will do a great job stick welding and I really want one, but I'm wondering if getting a TIG machine suitable for stick would be a better choice. Budget is also important. I'd love to buy a PowerTIG 250EX, and it's not that I can't afford it, it's just that I can't justify the expense at this point. You could certainly classify my usage as "hobby" for now but I can't stand using tools that don't do the job well, no matter how infrequently I might use them. Here's two options I'm considering right now and hoping I can get some comments on:
- Option 1 - Buy the PA200 and enjoy its great stick welding performance. Take the time to re-learn everything I've forgotten and develop skills. When I feel like tackling TIG, get a gas-valve TIG torch and argon bottle and live with scratch-start only. Maybe I can even get by with small-diameter electrodes for stick welding thin stuff ocassionaly?
- Option 2 - Buy the I-TIG 200 becuase it's not much more than buying the PA200 plus TIG equipment. I know it's DC only but I don't think I'll be welding aluminum so maybe that's not a big deal. But how well does it stick weld? I know the stick welding duty cycle isn't as good as the PA200 but I doubt that would become a limiting factor for me.
Thoughts anyone?
