I bought the machine with 750 hours on it. Since I'v put 50 hours on it with no problem. I wanted the 250 specifically because of price and its CAC capabilities. I just bought a K-2000 torch and some 3/16 rods. I was gouging with it (off and on) for about an hour, then it quit. I took it to the shop and one of the resisters blew out. It was about a $200 fix. I don't feel like I was over powering the machine. Maybe it was my fault, but I feel strongly that the machine should have had no problem doing the job I was asking of it. I have lots of CAC experience and I am well aware of duty cycle. My main concern is this going to happen again? Maybe the guy who owned it before me treated it like crap?? Or maybe I need to think about a new machine.... Or maybe I should just become a used car salesman. I would probably have more work.
Reply:Arc gouging is very rough on machines. The 250 amp should handle it but personally, I refuse to use my personal machine to arc gouge for any extended amount of time. I saw an SA 200 absoultly ruined while doing so...puking oil, smoked it.....
Reply:You have rethink your view on arc gouging, its really rough on your machine. Your machine should have been set at max so yes you would have been pushing your machine to its max. If you like to use gouging then get a machine with 400 amps or more and don't use any carbons larger then 1/4". |
