So my father in law gave me this old (20 years plus) arc welder and it runs on 110 v, 26.6 amps. I don't have a 30 amp 110 circut but I do have a 240/30 amp for my dryer which I could access. Can I just use a transformer to turn this into 110?

Theoretically, yes, but I don't even wanna think about how much a 30A transformer costs.

But you can grab one "leg" of the 220 circuit to get high amp 110. If you don't know what I'm talking about, you have no business mucking about with household wiring.

the welder will only draw 26.6 amps when you're using it at maximum output. at 'normal' welding currents it will probably work just fine on a 20a circuit.

Thats true, I'm just debating whether to hire an electrician to make it work, or just buy a new welder that I can just plug in from harbor freight.

On some of the welding forums, (yeah, I lurk there sometimes) they typically recommend a brand name - even if you're going 110v - Hobart, Miller, Lincoln - the Hobart 140 is a highly recommended model for hobbyists - about $475, but they say with the HF stuff, you will have buyer's remorse within a week.

HF tools are cheap and unreliable at best. I love buying them...but I usually consider them disposable, and I rarely buy anything over a few dollars without doing a significant amount of research. I did spring for the mini milling machine, knowing full well that I would invest 3x the initial cost in order to make it useful. I also own the 4x6 band saw that is quite popular with hobby machinists. Not surprisingly, the band saw requires a lot of tweaking to make it live up to its potential.

The welders typically have extremely low duty cycle ratings. Best case, they overheat and trip an internal protection circuit. It's more likely that they will crap out with very little use, and they tolerate no abuse.

I've had great results with their corded drills...the hf inverter welder gets GREAT reviews. If you're a pro, buy pro tools.......
