Ive got a Arc welder.. its pretty good but could get alot better
I learned on an arc welder. I've only dabbled with a mig, nothing too serious, just welded the slip fits on my pace setters. Also had to weld a nut on top of a nut for a home made engine stand that had stripped out that's holding my 5.0L.
It's been years since I've had to arc weld anything. When I was young, my dad basically let us do what ever we wanted with tools. LOL, the stuff I used to do when I was a kid would scare the living shit out of parents today.
You can really get some strong welds with a good arc. A/C and D/C welding makes a difference in splatter and heat. My dad built a rediciously overkill A/C -> D/C converter for a 110 arc welder that ran instream with the leads. It could only do A/C. IDK how it worked, but my dad is an electrical genius IMO. Some of the shit he does is simply amazing.
When A/C arc welding, the heat goes everwhere, splatters, it's just nasty. D/C stays at the end of the rod and makes prettier welds, but no matter what an arc weld is going to need some clean up. It definitely takes practice.
Best bet is to get some test pieces to weld and break them with a vise so that you can see how strong the welds you're lying down are. Who cares really what it looks like, I am more worried about the strength and penetration.

Edit:
Also, for those who don't know, don't weld galvanized steel.
