Own a Miller matic 211
S/N: MF421149N
The machine first shut down automatically on a initial tack weld. I presume it was a cord disconnect as i had some commotion around me.
Checked everything out. Reset the power switch, and the machine powered on.
The next tack also shut the machine down and will not power on now.
Neither tack weld ,auto shutoff , action actuated the re-settable C/B.
Coincidentally, i had a rotisserie motor stop functioning on the same circuit. Got distracted with it but that motor continued to work:
Got shocked on a 12v ground during trouble shooting.....which led me to check my outlet voltage.
I did some voltage checks on the outlets. The Voltage varied during 20 mins from 190-215 (I Live in Philippines where 240v is nominal), i had 3v-30v volts on the neutral an ground side during that time also.
Called out the Electrical Company and the lineman found corrosion on the Transformer Neutral, which was repaired: voltage back to nominal.
Opened up the welder and inspected for any apparent damage. Nothing but a little dust.
Checked continuity through the Switch and C/B. Fine.
Checked Voltage to the PCB. Line voltage at PCB. Fine.
Nothing burnt. Nothing Cracked. No discoloration.
Could i get some input on process of trouble shooting from this point.
Does the welder require a signal from the fan Motor prior to powering on?
I have yet to do a any tear down until i can get some feedback on possible simple solutions of troubleshooting!
