Ok, please don't all laugh at me. I am the wife of a welder who has been a "company" welder for a local outfit for several years now. He is currently outside rigging up his own truck. He has bought a machine from a friend of his and we are having trouble already. I'm sick of listening to the cursing, so I decided to see if I could find the answers myself. This is all I know...so here goes nothing. The machine cranks and runs fine, but it will not weld. There is also a 110v utility outlet on the front of the machine that is not working. He has cleaned the "armature" sp?? like someone suggested, and that did nothing. He replaced the 110 outlet and the new one doesn't work either. I'm not sure if this is enough info for some help...and I don't really know what I'm talking about so please bear with me. Any suggestions would be appreciated. Thank you!!
