Nozzle,electrode replaced

Postby Rudy198 » Sun Jan 21, 2018 10:42 pm

Hi guys I'm all new to this plasma stuff, We have one at the high school and finally got it running pretty good. One problem we noticed is the torch would dive in auto but in manual it was fine. So we cut a few pieces 3/16 in manual mode on the torchmate 4x4 using a hypertherm 1250. Some cuts we noticed have a slight bevel to it so we checked the nozzle and electrode. Looks like the nozzle needs to be replaced. My question is how many inches should a nozzle and electrode last if everything was dialed in?
We are running 60 amp nozzle ,60amps, 137 volts, travel speed 80. We found those settings in the HT manual.

It all depends on the moisture quality of air.
The drier the air the longer the consumables last.
Cut height being correct
Pierce height correct
If the nozzle contacts the material it'll damage it pretty much immediately.
The way to know is to check them like you did.

There is a section in the Powermax1250 (Hypertherm brand) operators manual that provides guidance on inspecting the consumable parts. Jim Colt Hypertherm
