Hi all. My 220V 100W chinese machine was running well and then cut out on me mid stream by flipping the circuit in the main panel in the shop. I pulled all of the accessory pieces off the line (220 water pump, fan, air pump etc.) and it still would trip the circuit.
confused and guessing that the PS was defective I ended up (and there is a longer story here) sending the PS and transfer board back to china for repair. Just got them back (they said they both DID need repair) put them in and the same thing happened!!!! This time I pulled the laser off the line though and put the accessories on individually, testing them one by one, and found they would trip the circuit as well, if not immediately, then with only a few seconds of operation.
I am assuming after all this time and money that it is most likely the 1500W step up power converter that is the culprit. So
- any thoughts generally?
- any recommendations for a good converter to replace this one with (power and brand)?
Thanks
