My brother brought his welding machine for repair. He explained the problem; as he was powering up the welder the earth leakage keeps tripping.
He had this machine for almost 15 years and although it looks beat up and old it is still doing what is supposed to do.
I powered up the machine and as I pushed the power button, the earth leakage in my shop was tripped as my brother explained earlier. I did not do any welding with it, just plug in the power cord and push the power button on.
A computer technician who has a store nearby brought this digital soldering iron for repair. He said that it suddenly went dead. He opened it to see if something was wrong but he could not find anything according to him.
The guy bought this on the net for cheap and he was not willing to spend any money on it because he could buy another one and will cost less than the actual repair. Read More

A bus driver and a friend of mine brought me this charger for repair. When I powered up the charger, the stand by light did not come on for some reason. I decided to open the charger and find out why it was not working. Let us begin.
It was very clear that it was repaired before because of the outside electrical tape wrapped around the charger.
