So I just bought a mig 250 from Eastwood. plugged it in and turned on. fan started spinning for half a second then a loud pop and spark from inside machine. tripped my circuit breaker aswell. after resetting circuit breaker machine will start and run (haven't tried welding though). opened up the machine and it looks like 2 mosfets melted. what would cause this? I run 6 other 220v welders off the power outlet so I know it works. (only one machine at a time) ill attach picture! THANK YOU SO MUCH!
