You don't say how old the unit is, the older the better. I have used these little cracker box welders 12 hours a day in a industrial setting. I like using a double 50 but you can get by with a 30 or 40.

If you check the data plate on the machine, it will likely say 50 amps.
It's a good habit to check data plates on any machine you buy just to be sure you know what to feed it.
Good luck with your new machine and have fun

Don't know exactly. From what I have read they didn't put any serial number, just an extended model number 9291-803.
As far as power, I would like to use it in our garage, which currently has a sub-panel that is being fed with #6 off a 30 amp breaker.
It does say 50 Amp, but I wasn't sure whether or not that was the required breaker or not.

You can run it on 30A but may not be able to use the higher settings.
Good thing you have 6ga wire. You can upsize that breaker with no worries

Why is your panel fed with #6 but only a 30A breaker? Is it an exceptionally long run? #6 is good for 55A, and an exception in the code allows you to round UP to the next common breaker size if the rated wire size is not available. So #6 can take a 60A breaker. Then put a typical 50A 3 wire welder outlet in there for the welder and be happy.
...It just occurred to me - you mean #6 copper or Aluminum? The above assumes copper. It would not be true for alum!

It's a long story. The subpanel that feeds to sub panel in the Garage had a burned part of the bus bar rendering some of it useless, so we had a local electrician come out and he moved some stuff around and was able to get everything to fit, but removed the 40 amp breaker and put a quad thirty in its place. I might see about getting a quad with 20-40 or the like, but I'm not sure what the likelihood of that is, as the breakers for this box are hard to find. A while back I tried to find a 20/15 but was unable to do so.

Sounds like you might want to replace the box with a new one that isn't burned and which you can get breakers for
