Help with Kemppi part
Hello everybody.
I have a minarcmig 180 adaptive that has problem and i can't find the part.
The failed part is a thyristor MKP 3V 240.
The google search results are litlle bit confusing and i can' t find direct sale on ebay , amazon etc.
Can anyone help me to find and buy this part?
Thanks in advance!
Dimitris

Is that kempi part number or what is printed in the device?
If the former, can you see number on the device.

This code is the thyristor number.
I think is a bi-directional trigger. I'm not sure.

Have you had it long and has it had much use. Bit worrying being a top of the range welder.

I know its old and very very used. I bought it broken in very good price knowing the risk to fail.
I try to repair it. The good thing is that the display and the settings on it working fine. I found a short circuit on the trigger of the euro
connector (conversion).
