The problem was it does not weld; At least that what the customer told me. Later on I realized, it was a different problem and was very easy to fix.
I took the cover off and turned it on and nothing happens, I was suppose to hear the cooling fan spinning but I did not, instead, I could smell something burning and the smoke was coming out of the cooling fan. I turned it off and looked closer at the fan. I tried to spin it by hand but it did not spin. It was a bad burnt fan.
A bad not spinning fan does not mean the welder is not working. The machine is working fine but the fan is very important in that machine. If the fan was not working and the machine is working, eventually, after a while the machine will go into shut down causing over heating caused by a fan not spinning and cooling off the machine.
It was a 220 volts fan. The motor was completely burnt and the plastic around the motor was melting and it smelled bad. The only problem I was facing in this machine is the ordering of a new fan. It takes about a week or so to get it and the customer was in a hurry to get it fixed. I called so many stores but without any luck. I have to place an order and wait for it.
I remember a while ago, someone brought me a DC welder to be fixed but it was too expensive and the customer did not come by the shop to pick it up. I went to the storage room and found the machine. There were two working fans in that machine. I called the customer and told him if he is interested to sell the DC welder for a cheap price and he said he not need it and offered me to take it for free. That was nice music to my ears; I took the old machine to the shop, took one of the working fans out and installed it in the machine I was working on and the fan worked very nicely.
I took the machine to my brother’s shop next door, connected all the wires needed for the welding process and turned it on. The fan started to spin and my brother tried the machine. It was working fine.
Called the customer to come and pick up his machine. He was so happy that the machine was working fine and was fixed in a very short time. He was happy, I was happy. Case closed.
