Hello, I think the techno has evaluated the maximum cashable power against the characteristics of the power transistors. Did it reinforce the soldering of the circuit break that I had pointed out previously, because the loss of power by the Joule effect at this point must ...

hi buddies, that's it my post is repaired, the technician told me that it was the power transistors that broke, in photo 1, we see that he has redone the welds (I did not disassemble everything from afraid of doing something stupid) and in photo 2 he must have also changed this part which was s ...

You have to examine with a magnifying glass and move the heavy components while watching at the level of the welded legs. A circuit break will thus be detected more easily. It is also possible that the copper rod that we see in the foreground, has come into contact with the legs of the transformer at the time of ...

Hello, If there has been a fall, you have to look at the heaviest components. There seems to be a crack under the big transformer. The printed circuit tracks are under the green tropicalizing varnish and it may be a multilayer circuit. It is necessary to scratch and check in ohmmeter if no pi ...

There seems to be a crack under the big transformer. The printed circuit tracks are under the green tropicalizing varnish and it may be a multilayer circuit. It is necessary to scrape and check in ohmmeter if no track is cut. Solder wires to bridge the cuts. Waaw you have the eye ... I ...

if you have a very strong hold somewhere, try it.

I tried on a circuit breaker 32A and jump

20171017_155920.jpg hi buddies, attached the photos of the soldering station and the circuit, at first glance no component is burnt (visually I say well), no thing melted or blackened, I looked if there is had a fuse but there is no, no wire disconnected or touching the ca ...

hi Christophe, the circuit breaker is 16 A and it is not a differential, I tried on a bigger one 32A and it also jumps. It was probably a component on the circuit that burned down, but I don't know which one.It worked fine on 16A no problem, until I dropped it ....

hi everyone, I have my inverter welding machine, a Deca starmicro 180, which trips my circuit breaker when I turn it on, I admit I dropped it because I had not taken it well in hand , if a person can help me to know what to do and how to fix, because there is no repairman ...
