Welding Machine Repair- Repaired But Ended Up With A Bad Argument With Customer
This customer brought this tiny welding machine for repair. He is a welding technician from out of town; he seems like a nice guy when I first met him but found out later on that he is completely the opposite of a nice guy, a trouble maker, here is the story.
He brought this machine and it was already opened. I checked it for shorted and founded some parts that needed replacement. I contacted the guy about repair cost and he totally agreed to that. I usually record conversations when I am dealing with customers and I usually tell them the call is being recorded and they agree to it.
Based on the agreement between the customer and myself, I proceeded with the repair and when I am done I will call him for pick up.
I found that two of these IGBT’s were shorted out. The part number is 60N60FD1 which is 600 Volts and 60 amps.
As seen, both these IGBT’s were shorted and needed replacement but from experience I know when these parts shorted to ground it shorts out another SMD components along with it.
I found these resistors shorted out and had to be replaced as well. Once I was done with that, I replaced the shorted IGBT’s and tested out the machine, I called the customer to come for pick up. The guy answered the phone but refused to pay the amount we agreed to. I asked him to come over so we can talk about it but he refused for some reason. Instead, he said that he does not want to repair the machine anymore and wanted me to undo anything that was done to the machine.
I did not want to get into more argument so I told him I am willing to do so if you pay me for the time spent on the repair and undoing the entire repair that I have done to this machine, again, he refused.
I was fed up with this guy and told him, the machine is up and running, if he wants it come and pick it up and pay for the repair and if he refused to do that in a month time, I would sell the machine. He did not say anything about that but instead he hung up the phone and a week later a guy came to my shop and wanted to pick up the machine and he paid for it in full.
That was a strange ending to a good repair story but life goes on and we learn along the way.
