Lincoln AC/DC wire

admin

Hello all, what a very informative form! I am glad I found it. Lots to learn. I have a question about a Lincoln AC/DC welder that I purchased second hand. My amperage on 105 DC does not work, and upon taking the machine apart, I found a corroded and burnt wire. I am wanting to replace this wire, and see that it unscrews from the amperage selector, but it seems to be "glued" into a paper wrapped component which I believe referred to as a "primary winding"? (please forgive my lack of knowledge). I have posted a picture of the wiring diagram. It is the 175/105 wire. Does anyone have any experience on how to remove and replace this wire from that paper winding?Thank you very muchJim

Reply:Oh, and if you go picking at the windings on the transformer, keep in mind that they're coated in lacquer. I'm not going to recommend how to do this (I is no expert!), but I may or may not have had success using aerosol lacquer.Sent from my Lincoln Buzzbox using Tapatalk
