how to fix a welding machine








A welding machine salesman brought this welding machine for repair. He explained as the welding technician was welding at this shop, he heard a popping sound and the machine stopped working.

It is not the expensive kind but good enough to get it back to life the salesman explained.

how to fix a broken remax welding machine

The layout of the board is almost identical with a welding machine this size usually but the main parts numbers are different.

This is a double board welding machine and in order for me to get to the electronic parts in between the boards,

I have to de solder them away from each other and check the parts.

It was not the best de soldering job but finally I managed to get the two boards separated and exposed the inner soldering joints.

When I started to inspect the board, I found this cut in the trace that connects to the main capacitors on the other board.

And in the same area I found a cold soldering joints that needed some attention and once this was soldered the way it should be, I moved on to the other fault connected to the burnt, cut trace that I found earlier.

I found this broken trace under one of the main capacitors and I had to solder off two capacitors to fix the fault then later on I added UV mask to cover the exposed wires.

I traced where the burnt broken trace go to and I soldered a jumper and then soldered the two boards back together because that is the only way to test the machine.

Of course I did a full check up of the area before soldering the two boards back together and hoped for the best.

testing dc voltage of remax welding machine

I was so glad to see the reading on this multi meter otherwise I have to take the board apart and look for other faults. Of course this reading is a little bit low since the machine was powered through a current limiter but when I powered it through a usual house power, it was showing over 75 DC volts which are perfect for such machine.

Mission Accomplished.
