I have a little lincoln wire feed welder that is going in the scrap pile. It's probably the smallest they make. No argon set up but I think you might be able to add it. It took a hit from a forklift once but had it repaired by lincoln.
Might be good for someone who just wants to mess around a bit.
my young lad could play with that. what's scrap prices up your way?
that reminds me of my parents next door neighbour. the father comes over (when i was visiting my parents) and asks if i could take a look at the little mig welder someone had given his son (early teens), knowing i have some welders of my own. kid was positive he was doing everything right but couldnt make a pretty weld. the welder was set up for gas (the wire wasnt flux core) but they never got the regulator when they were given the welder so they didnt realize this. so here he was mig welding with no gas ..... as mentioned, he just couldnt get a good looking weld.
