The last time I bought 50 feet of 12/3 I had the makings of a heart attack. I put 10/3 into the conduit run to the other side of the garage door where I put the 250 v plug for the Sheldon just in case I had to unplug it and plug in a stick welder. I can remember when that would have been my weekly paycheck! And the only welder I own is a MIG that plugs into a normal wall outlet. And TBT its something I've not mastered all that well, so my oldest son from Ruby usually gets the pleasure when he visits if I have something to weld. I get along with a smith wrench a lot better, took lessons from an army/navy certified guy in the early 50's, but bottle rent is a #$%&@ racket, so while I have the smith wrench, no bottles to feed it. He was damn good, I watched him fix the hole in the side of a Magnesium big 6 Mercury OB engine block where a broken con rod came out. But the block was junk anyway, warped beyond fixing with an align bore machine, so he did it on the sidewalk well away from the store, and after we had all inspected the patch, he showed us what happens if you don't pay attention to the puddle, it burned for about an hour, brought the fire dept, which we had to stop from pouring water on it. That would have been interesting, from a block away. Nice sized hole in the sidewalk he had to fill and patch the next day. Fortunately no close residential neighbors. Made the local fishwrap complete with pix the next day. Told me w/o a word, that I wasn't THAT good. But I have put his lessons on flame control to good use over the years, with zero weld failures even years later. MIG doesn't give you even a hint of that kind of control so you usually buy flooding gas that 25% carbon dioxide just to harden the puddle some by adding carbon to the puddle. Its the argon thats ex$pensive. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
