Hi all,
Can someone can help me solve a mystery with a Miller Spectrum 375 plasma cutter. It's an older unit (not one of the newer "Extreme" models). I bought it used and when I plug it in at my garage it powers up and when I pull the trigger on it, it strikes the pilot arc and then immediately cuts out and the power light flashes on/off. According to the manual, that means there are power related issues.
It's plugged into a 240V 50Amp plug. I've checked voltage at the plug and it's correct. I use the same outlet for my welder and it has no problems running off that outlet.
I've put all new miller consumables on the plasma cutter. I have also verified the air pressure. FYI - The cup (consumables) and air pressure error lights do not come on.
I've taken the plug apart and cleaned up the connections and verified it was wired correctly.
I took the plasma cutter back to the guy I bought it from and plugged it in at his shop - it works perfectly. Cuts like it should and does everything as plasma cutter should do. Take it back to my place - it strikes the arc and then cuts out and flashes the error light.
What am I missing?
