Hi All,
Apologies first - I know nothing about welders however I am an electronics engineer and my brother in law has asked me to try to repair a circuit board on a welder. The board is made by AWELCO, an Italian company.
The board has the following markings M702900 an MIG01B which I have used with a Google search to find a company in Russia which may have the board.
The main current adjustment resistor has been damaged beyond repair so ideally I would like to obtain a replacement for the component but due to the damage there are no markings left to identify its value. A circuit diagram which would identify its value would be great but the Awelco site only provides basic information on welder models.
Is there a distributor for Awelco in the UK and would they hold spares?
I have attached an image of the circuit board where the damaged variable resistor is shown on the bottom right side. I believe this same board is used in a number of models, not only Awelco.
If would be very grateful for any help in identifying the component and its value or alternatively a circuit diagram or replacement circuit board.
Thanks.
