HELP Please! Pmax 45 strange noises

[skyecyn]

I have had my cutter for about a year and a half, and we just moved to a new home/shop. It worked just fine when I shut/tore down but when I got everything back up and going and rewired I am having issues. First when it would touch off and try to fire the torch I could hear like a poping/clicking sound coming from inside the case constantly repeating like it was trying to fire but couldn't. If I let it keep doing it for a couple of seconds it may fire and cut a really bad cut, other wise I would just stop it. Now today If I try to fire it does nothing but make a crackling sound inside the case and no air movement or anything. Since I have had this unit it has made a crackling sound faintly inside the case at idle and from reading Jim Colt's posts on some forums this seemed to be normal so I did not ever worry about this. But this is the sound I am hearing when it tries to fire now only much louder. Any help would be great. Like I said it worked just fine before we moved it to the new shop.

Thank you!!

The free call to Hypertherm tech service will be well worth it. Tell the tech the symptoms and work with them, there is no group better to help you solve issues with a Hypertherm plasma cutter!

The Powermax45 does make funny internal noises...these are only audible to some as they are produced by the internal inverter at a relatively high frequency (I have never heard it...but after 38 years in this industry I have lost a lot of my higher frequencies). The sounds you are hearing now are described differently....almost sounds like an electrical arcing....which would tempt me to pull off the cover and see where the sound may be coming from. It could also be something plugged or sticking in the internal air plumbing....is air coming out of the torch? Are the cut pressure LED's saying air pressure is correct?

Call tech service!

No error LEDs are showing all normal, no air is coming out of the torch. Yes I am going to call them today but while I was waiting for them to open I posted on here to see if by chance someone else had the same problem. I am going to call them soon. Thanks again.

Maybe pull the cover and give it a blow out with the air line?

Might be some muck got dislodged in the move.
