I'm one of those old guys that believes that practice is the best way to learn something; so I've been practicing on Tin Cans in the hope that I can learn how to weld sheet metal at some point down the road. (Don't have any scrap sheet metal to practice on just now.)
I took a bunch of cans, and tack-welded them end to end using 3/32" 6013 rods at 30/40 AMPS with my Lincoln 225/125 AC/DC welder.
The cans held together well when I took the entire column and beat it against my Railroad Baseplate Work Bench; so I guess I did something right; but I'd like to know if any experts/old timers out there have any advice on a better rod, etc.
I did have several spots where the arc burnt through the cans; but for the most part, the job came out pretty well had I wanted to make myself a smoke stack.
Thank You !
