Re: question about diode of an old welding machine
so sir to understand better
The foot of the diode that seems to go to the metal plate in a point like insulation you can see in the picture i have tsese points in circle is not glued with a rod I mean but it is like nailed inside so if I pull the passage up its foot will come out from the inside and the new one corresponding to the old diode I will press it inwards at that point where there will be a hole left to nail correctly I understood ?...Leave a comment:
