Did I do good?

I picked up a welder found on CL earlier today.
It's a hobart 130xl with regulator and a full spool of flux wire. I also got a full 20ft3 bottle of argon (100%, no c02), gloves, and he threw in some scrap for me to practice on (i'm a newb).
All for $250.

Now who's gonna teach me how to use it?

correction, not a 130xl, its a 135 handler

Sounds like a pretty good deal. Get you some solid .030 or .035 wire to use with the gas and practice. I used a Miller 130 for several years, fabbing multiple bumpers, sliders, skids, etc and it was a workhorse. IIRC, Miller and Hobart are the same gear.

Yup, in fact the gun is a miller
