mouse wont work when firing

[Littlebrosfab]

i was running a thermal dynamics 39 cutter and upgraded to the esab 875 i wired up the card the same as before and now im having cutting issues and as soon as it fires my mouse wont work

when i get it cutting my tip volts are only at 55-57 my old machine was at 90 i would think it needs to be higher

Your getting hi-frequency noise grounding through the PC I am willing to bet. Which ESAB unit was it? Is it high frequency?

how do i fix that? it an older model ESAB PMC-875

If its a wireless mouse their is no fix for that. Proper grounding is required to run a hi-frequency unit but this wont help with a wireless mouse. Luckily the electronics we use are completely isolated and great care is made to ensure they do not get damaged from hi freq. Have you tried using a Xbox 360 controller to start/stop and jog?

it's just a usb mouse i have the xbox controller but i can't get it to work

You will have to move the PC further away from the plasma. Like 10 feet at least.

ok i can try that do you have any idea why my tip volts are are around 55 i thought they would be a lot higher with this plasma

Call Esab to see if that unit is capatable. You may not be getting true arc voltage only divide volts.
