Have you done any other sort of welding? If you have then I would not
put a lot of effort into finding a welding school. My experience with
welding schools is that there is very little instruction. It is 5%
instruction, 95 % practise. But of course that 5% can be invaluable in
getting started.

I took welding at a Votech night school when I was a teenager. All
they had were oxy/acet and stick welding. Many years later I decided
to get a TIG welder, but before I did that I thought I ought to try it
out. Being over 60 years old, I was able to go to the local community
college at minimal cost. There were only two of us interested in TIG
and a mess of new students taking gas and stick welding. Over the
length of the course, I got maybe an hour of instruction. Maybe I
would have gotten a lot more if I had needed it, but my experience with
gas welding let me know what I wanted the puddle to do. And the rest
was just adjusting to the differences between gas and Tig welding (
which took very little time ).
