welder/welding

I've probably taught 40 plus people to weld and get certified that came thru my shop over the years. Even gave brief lessons to a few members starting out at there homes.
Welding is just proper wire, gas, and position. I use argon co2 mix. unless it's Flux core, . Flux core comes in the same dia. As standard wire.
The rest is just practice.
I still do a fair amount of outside welding so Flux core it is. Or fire up the old stick welder..
I had a guy tell me when I was a kid "welding is just melting three pieces of metal together" and that really simplified it for me.
