Default weld quality

Practice then test your welds Jody on tips and tricks shows hot to do an easy etch of your test samplls to check your penetration. ..a few years ago I stopped at a friends house and his high school age kids had traded for a T bucket project from some high school buddies. The frame was a little tweaked and I said I could fix it with my High lift Jeep jack and a piece of chain. It didn;t take much pressure and the welds starting breaking. That is the problem with Mig welds they can look purdy on the outside but no penetration Practice then do bend, cut samples and etch and if possible do a pull test.

We were taught the basics in Ag class, and got some hands on experience. Stick and torch, Mig or wire welding wasn't that popular yet, nor was Tig. I welded on a construction site, Govt job, got certified by the Army Corps of Engineers to weld on the site. Got better the more I welded. This was on heavy gauge steel. Learned how to weld without blowing through, and learned how to cut with a rod when a torch wasn't around. Ever try cutting a #9 rebar with a stick welder? When I left that job, it was several years before I picked up a welder again, and it was just like starting over, I had to relearn a lot of what I used to know. Finally bought myself a gasless mig, 110 volt China box, learned how to use it pretty good, then it got stolen. I replaced it with a 110 volt Lincoln Handy Mig, gas/ gasless, it's a much better machine. I still use my old Lincoln 220 volt buzz box stick welder for heavier gauge metal, but for sheet metal or thin stuff I use the Mig with flux core wire, still haven't gotten a tank yet for gas.

I can't lay down pretty beads anymore, eyesight just isn't what it was even with glasses, but seldom have a problem with welds breaking. But, I do own a couple of grinders, if it needs to be pretty I can always smooth it out. I'd rather have to fix a blow through and know I got good penetration than have a pretty weld that is just on the surface.

I still wouldn't want to trust critical welds on a chasis to a guy with my welding experience (which is fairly limited) and a 110v machine. I want to take as much error out of the equation as possible.
Not so current build - '29 A Rats-N-Rice. Drivers! - '48 Olds '63 F100. Pile of parts - '30 Tudor.

Images of that 50ish IH cab grafted in the middle of a 90s Pontiac grand am are still burned into my brain like seeing a fat aunt naked. - ???
