When you take your classes try MIG on some thin tube, I think that will
answer your question. There are some nice TIG welders out that run on
30a/220v like your clothes dryer does. But don't spend a lot of money on a
welding rig until you have had those classes. You will know what you will
need by then.

Just wondering what the general consensus is on the best method of
welding 4130 tube structures. Advantages / disadvantages of each
considering I will be building in an attached garage, in a residential
subdivision, and will be limited to a 110AC/ 20 amp service?

Is an off-the-shelf MIG unit like a small Lincoln or Hobart worth the
money? Anyone have any experience with these machines?

I don't have to weld anything right now, but I'm considering taking a
few classes.

Thanks,
Harry
