Lincwelder 225 resistor grid repair question

admin

I bought a lincwelder 225 about a year ago and haven't tried welding with it until recently. When I did it barely made a spark and no real arc was achieved. I took the cover off to inspect the brushes but found out the grid resistor had corroded a bit and had broken in two spots. In researching I have found very little about these resistors and would like some more info on them. Can I retrofit with a different style that is less prone to breakage or am I better off to repair the existing one?How do I go about repairing the existing resistor? Silver solder? brazing?Any help or info is greatly appreciated! I normally just run the bead... not fix the welder
Reply:Get an electrical diagram from Lincoln.You cant repair the existing resistor.Over the years I have learned I have to fix tools I use.Resistors dont break, they over heat and open.

Reply:The second to last picture in post #4 shows the resistor Im talking about.  If it is this type of resistor, then it can be soldered.http://weldingweb.com/vbb/showthread.php...esistor+repair
Reply:Yes! That is very similar to the type I have. Silver solder it is!! I'll update as to how it worked!Thank you!
Reply:So... Silver solder is a no. The fuse/melt point is too low and the flux burns off before the metal can even come close to temp. I ended up using a standard brazing rod with an oxy/act torch barely on to get it together. So far so good, it reads continuity across the terminals. I'll install it tomorrow and see if it worked!
