Reply:Whats the symptoms?  Is it dead, poor arc etc?
Reply:Hello! Thank you for your answers.The following prats were damaged and were replaced:PD1 - rectifier bridgethe resistors R3, R6 and R7But still does not works (led D25 does not start either the K2 relay connects)If it helps the machine that i've got is exactly the same as the image.
Reply:Sounds like a power supply problem (PD1). Is it dead?
Reply:The PD1 was dead, but i've already replaced it.I have 5V voltage at some points and changed the optocoupler (not for one exactly equal..)
Reply:If is like a ZX7 board.Do the fans run, I think the fans and the led run off of the 24v supply.Does this mean the relay clicks but there is no led "(led D25 does not start either the K2 relay connects)"
Reply:Their is a Chinese welder user group on yahoo that may be of some help, I have had luck repairing my imports by looking for burned parts or the smell their of. Courtesy of ups dropping the welder, but I made out good on the deal.Got a replacement then later fixed, the broken unit. Any reason  you cannot go back to the original mfg of it. Their is also an american repair tech of If recall in the midwester states but don't have the contact info off hand. Sent from my SGH-I747M using Tapatalk
Reply:Thank you for all your aswers/ help.The relay does not connect and I believe that the SMD module should be also dead (burned with the PD1) so will wait for better days, or will be used to make parts for some other machine.Thank you!!
