How did you learn to weld?

I just picked up a new holbert 140 with cart shipped from nothern tools for $499 as an extra small sheet metal welder.
Why pay $200 for junk?

Do you have any friends with welders?
3 weeks ago I showed a friend how to mig.
Gave him some scrap sheeet metal, and let him go at it.
After about 3 hrs, he started to get the hang of it.

Welding takes alot of practice.
The basics are the same if it is brass, mig, tig, al,.
Heat the metal and lay a bead.
