Lincoln 255 Mig Too Hot

admin

My 255 digital display went to Too Hot and won't function and if I unplug the gun it goes back to heat and wire speed but still will not function.The fan is running and it still does it after sitting unplugged over night.I lost my manual in a house fire in 08 so I don't have that to fall back on.Any advice is appreciated.
Reply:The manuals are all available on-line from Lincoln . . . FYI . . .
Reply:Found out it is probably a thermal overload that went bad,trouble is I can't find the location of the part.If anyone know please share the info,thanks!
Reply:There should be a round? device somewhere close or on the transformer with two light gauge wires attached to it.Or look for wire #320, 320b or 325 they all lead to the overload device. http://www.lincolnelectric.com/en-us...+255&type=name This is where I found the wiring diagrams. Still could not tell exactly where to look.But do a little looking I think you can find what you are looking for. Good luck.Last edited by tinker001; 02-22-2016 at 11:28 PM.Klutch 220si mig , stick, and dc tigHobart 140 AHP ALPHA 200X 2016Lotos LTP5000DSmith O/P
