While I'm sure there are some, I've never seen a broken Lincoln transformer based stick machine in my entire life. I think 20 bucks was a safe bet.
Very few of them ever burned up. I have ran them wayyyyyyy beyond their duty cycle and then some. I like the thinking of the post above this , the AC is better than no welder, cant be beat for 20$ and have a value of 75-100, the 50$ DC is a bargain.
Back in the day it was a joke among construction workers, pay 100 more for a DC welder and never have to buy rods.
Baking those electrodes probably wont help much unless water is dripping right off of them. My bet is they are 6013, they are designed to have some atmospheric moisture in them. If they have been laying a long time in one spot they often tend to "fingernail" too. The heavier elements in the coating tend to sag around to one side.
I have 10 machines, am a career welder and this is still my go to shop and outside apron machine. Its hooked on a common ground grid with extensions and 2 stingers, can reach without moving it.
I remodeled a few years ago, pic 3 is all the snot I took out of it. Pic 4 youi can see the edge of the door jamb, apron out there and these are the leads to reach out, ground shared with a plasma.
