Hi guys!
We have a multicam 1000 table with a hypertherm 1250 cutter. When we cut anything below 9mm(using 60 amps or below), the plasma is working great and dandy. But when I cut anything above 9mm to 1/2"(using 80 amps), the cutter keeps on turning off, the circuit breaker keeps on tripping. I mean it cuts the initial holes, but when the long ones are cut, the control will show waiting for plasma arc.
During this, when I check the plasma, the circuit breaker tripped off. I asked the distributor here in the Philippines why was this happening and they couldnt answer me. They just said that they will follow this up to Hypertherm USA, but its been 3 months and still theres no reply.
Any of you guys encountered this problem? oh yeah BTW, once i turn on the breaker again, the fan of hypertherm is roaring like wild, so I have to turn it off and on again just to have it to rest.
If someone could point me to the right direction, it would be greatly appreciated! I tried checking the manuals and technical manuals, but theres no problem with 9mm cutting or more. So I'm guessing theres something with that I havent looked on.
Cheers!
Martin
