Need mag amp assembly for SP-200

admin

Hey guys,I am looking for a mag-amp assembly for a Lincoln sp-200. The welder code is 9106. The part number for the mag-amp assembly is M14107. Yea, I know that I need a couple of diodes too, but those are readily available. Lincoln says that the mag-amp assembly is "discontinued". Any help in locating this part will be greatly appreciated. A good used one would be fine.Here is a picture:         http://s1055.photobucket.com/albums/...nSP_200035.jpgThanks.Last edited by davido30093; 01-14-2012 at 01:44 PM.
Reply:Update:Since I was not able to find a mag-amp assembly for the SP-200, I decided to try to fix what I had.Before:http://i1055.photobucket.com/albums/...nSP_200035.jpgAfter:http://i1055.photobucket.com/albums/...3/DSC00058.jpgThat red stuff is not paint. It is red insulating varnish: Meets Class F requirements, dielectric strength 2,600 vpm, resists oils, moisture  acids, alkalies, and is suitable for motor and transformer windings.The repaired mag amp assembly  checks OK electrically. I am going to order the diodes and put it all back together. Hope it works.Last edited by davido30093; 01-24-2012 at 05:07 PM.

Reply:Nothing really special. I am a retired EE and just started learning welding about a year ago. Repairing just about anything electric or electronic is what I have done for more than 40 years. I started to welding school about a year ago and just now got to tig, so I was not very confident in my tig skills yet. I decided to use aluminum brazing rods to repair the broken and melted coils in the mag amp assembly. A couple of them were completely broken/melted and had to be "rebuilt". Others were simply missing some of the material. The coils were obviously aluminum so I used a steel plate between the coils to build up and repair the broken coils. Then epoxy to hold them in place. A dremel, files, etc. to shape them and finally a good high dielectric varnish to insulate and protect them. Probably about two hours of actual time invested in the repair, not counting cooling and drying times. This is the second old welder that I have repaired recently, and since there seem to be a lot of them around that need attention, I may be beginning yet another career. Thanks for your interest and compliment.
