Got my old miller 135 working again, had a bad resetable fuse (Thermal).
Ordered a new 0.51$ part and soldered it in. Common issue with these welders. Works great now.
I "somehow" got ahold of a miller Tech manual and was following all the steps to check the board.
That little Yellow fuse at loc. PTC1 is the issue, its getting too hot too fast.
Tore apart the motor and cleaned and re-greased to prevent any extra stress on the circuit.
Its alive! and welds good. I picked up a bottle of C-25, I always had flux core in this machine because it was free haha.
I havent mig welded in years.
Then this weekend, after I fixed my old one I saw a gem pop up on craigslist....
Miller 251, only used for one job. Minimal hours, very taken care of. Guy wanted 1300$... A steal still..
He was 1.5 hours away, I offered him 1k....
He bit..


Weld was too hot, because I followed the settings for C-100, not C-25.. oops
Ive never owned a 230V welder.. This thing is awesome. I was hesitant for a digital interface, but for 1k... oh well. I was gonna buy a new Ironman 230 for 2k with spool gun.... theres someone on CL in my area now with a brand new 30V spoolgun for the miller for 800..... I can get a 251 with spoolgun for less than the hobart.. I might do it.
Now I want to make a shelve for my 251 so I can mount my 135 above it and keep .023/.025 wire in it for body work.... Maybe incorporate my plasma and tig/stick but well see. Id like to key both my regulators into the tank though, that will be another days project.
