XPR 300 Pilot Arc Timeout

Post by JakeGG » Wed Jun 22, 2022 4:16 pm

Having an issue where the table stops cutting on the second part of a job and gives a pilot arc timeout error message (error 521).

The program is setup to cut many parts, piercing for each one. It will cut the first part fine then when it comes down to pierce the second part there is a quick flash of blue light and it doesn’t cut. You can close the error message and start cutting again and it will do the same thing cutting one part then stopping.

Changing the consumables ‘fixes’ the problem, but the consumables we take out don’t look that worn (see attached pic). Causing us to go through a lot of consumables. Is there something else that may be causing the error?

Verify you are using the correct pierce height. if this is correct then you need to perform a torch lead test. page 313 of your XPR Manual

Definitely physically check the pierce height with feeler gauges on the initial and second cut that doesn't work, shouldn't be a difference between the two but I would certainly check it. When the torch lifts up to the pierce height just pause the machine and measure. Get back with your results :Like

Hi JakeGG,
I forwarded your post to our technical support team here at Hypertherm and they wanted me to relay this message.

"I would have him call in to Tech Service or email us for more support, but sounds like it could be an issue with his Ohmic IHS. He is likely resorting to using stall force on his initial heigh sense and is getting some plate deflection and then the torch is not in the correct position to transfer to the plate. And If it is not that then could possibly be an issue with his gas flows.

Either way if he gives us a call or shoots us an email we can help resolve the issue".

Very much agreed! Piercing too low can reek havoc on electrodes. There is a good reason why the pierce height is generally at least twice the cut height. And cutting too low will be just as bad. I think it was already mentioned, but you might want to pause your machine while cutting and physically measure your actual cut height.
