Buddy of mine works at a surplus store that purchased a bunch of Lincoln Hobby-Weld fixed 50 amp welders from an auction. Everyone they sold the units to has returned them as defective so he told me I could have them for free. My son is a welding shop foreman and he checked them out and they all work, but not well. Running the 1/16" recommended Lincoln rod a very short bead causes all the units to stop arcing and the bead has to be restarted.
We really don't need these things so my question is can the problem be solved so I can sell them or are there any other uses these toy weldering machine could be converted to?
Thanks in advance
Jimbo
