Hi to all, I'm Diego. I'm an electronic technician, but I had never repaired a welder before now ... Normally I design things, not repairing them... but... This welder is arrived to me as a gift from a friend. Of course that it have some problem and my friend told me that he had just contacted the service for a repair, but they told him that this model is to old , and there is no more spare parts.... so... more fun for me ;-P
No one that have a schema? Many components on the primary board are missing...(smd components) on most of them there is some burning traces..... A part to check all of the mosfets/igbt , the display board seem to be ok... So how to proced? Ah...maybe can help I know the basics of TIG welding (I learned home with my friend)
Many thanks to all, and of course sorry for my horrible english... Bye Diego
