TigWeld 250 vs 315

With only a $200 difference, I am starting to look at the 315. By looking at the specs, both will weld real thick stuff, but it seems like the 315 might be the way to go. Just just never know if you might need it. I guess I look at like a twin-turbo big-block on the street. You probably never even touch the power, but you never know.

Any suggestions? I mostly weld .120 wall tubing, but I plan to start some 4x4 fab on my K5 blazer. I will be welding some 1/2" brackets and such.

And I might make a girder front end for my bike and will be welding up 1" stock for the upper triple tree. The 315 says it will weld 1", but I will definitely be beveling the weld, so I think either machine can perform that weld.

Is it better to get the bigger machine and do one single pass, or is multiple pass welding ok if done correctly?

Don't forget, the 315 is a 3 phase machine.

Didn't even realize it. In that case, the 250 will be the better choice. Thanks.

No problem. Most of the 3 phase machines are marked in the comparison charts, that one isn't.

I have a Lincoln Precision TIG 185, it's nice and I live with it, but I always wanted a 250. My Miller MIG was a 250, and it was more than enough.

I think the 250 is what I want to go with. A 200 would probably be good enough, but I would hate to realize down the road that I should have bought a larger machine.

Too big is almost never a problem, too small often is. Good choice.

Seems the key differences in the TIG machines are

200 - tig no aluminum
250- aluminum and single phase
315 - three phase

yes?

Tigweld 200 is DC only single phase and will not weld aluminum
Tigweld 200 DX is AC/DC single phase and will weld aluminum.
Tigweld 250 is AC/DC single phase will weld al
Tigweld 315 is AC/DC three phase and will weld al

For the projects you tackle,I would choose the 250 also.Just in case.
