Hey guys,Was welding hard wire .35 wire and mixed gas with me Miller 252 Mig welder . Purchased it new couple years ago. Never had a second of trouble with it. Was welding 22ga steel at 15 heat and 88 speed. Been welding about 30 minutes and it started blowing the metal out. Like I had it setting on 24 heat for 1/2" metal. I checked the settings, changed the tip. Did a reset of the machine. Unplugged , plugged back on. Same results, Dial shows heat setting changing as I turn it. No matter how low I set the heat, it does not change the heat output. No help in troubleshooting guild. Anyone seen this?
Reply:Just a wild guess - sounds like a possible issue with weld output voltage feedback to the main control board PC1. Poor/lost connection or even PC1 failure.MM200 w/Spoolmatic 1Syncrowave 180SDBobcat 225G Plus - LP/NGMUTT Suitcase WirefeederWC-1S/Spoolmatic 1HF-251D-1PakMaster 100XL '68 Red Face Code #6633 projectStar Jet 21-110
