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


A clear close-up photo , placed in wwwland, would help, assuming the
blown off components are just minor components .
Anyone else placed an image out there somewhere?
A board from a "spares or repair" sale on ebay , assuming different
problem, may be the only chance.
