Title: ZD-937 issue
Post by: floresnico on January 14, 2017, 04:57:23 pm

Hello. I have a problem with my ZD-937 welding station. I have a resistance that has completely burned. I want to change it but I do not know its value. Would anyone have a ZD-937 station to give me the value?

Thank you for your help.

Hi,

I've attach a picture of my ZD-937, the point that you've marked are connected in short.
I've checked the image  IMG_20170114_173421 - 2 (Copier).jpg; I've found my board is slightly different from yours.

Let me know if I can provide other details to you.

Thank you very much

Maurizio
