Well I have a brand new Hypertherm 45xp hooked up to the crossfire xr and torch won’t fire, I pulled the machine torch off the table and can’t get it to fire by hand either, any ideas before I call Hypertherm, no air or arc coming out of the torch,
Machine torch only, COC cable from Langmuir installed Mac 120 psi straight off the compressor, what I meant about the yellow light is that it comes on when you turn off the switch on the torch indicating that the switch is working. And yellow light turns off when you turn the torch on, it’s on cut mode also, only thing I didn’t try yet is to unplug the Cpc cable and see if it fires
Sorry I’m just still working on setting everything, I have everything to do it right with dryers and what not, just trying to see something work for the 12k I just spent ya know, so last night I just hooked up the air hose to try to cut a scrap piece
I had the same issue when I hooked up my Hypotherm 45xp. I checked my air tank pressure gauge, and it was at 120psi but the gauge from the dryer/water separator was at 65. Once I cranked up this pressure it worked fine.
I’m having similar issues- 45xp machine torch won’t fire consistently. I can often hear a click when it’s supposed to start, but usually no air and no pilot. Following this thread, I tried “jumping” the torch on/off cable as suggested and it did fire. What are my next steps? Replace that cable? Happy to share more about what it’s (not) doing and what I’ve tried if more info is needed. Thanks!
