Arc OK intermitent issues on torch fire

Either one will work fine

Thanks a ton! I am still confused about exactly where PCW was suggesting I fuse the isolated 24+ and torch sense cables a few post back... but I have plenty to do in the meantime. What size fuses did you use?

PCW - As I was wiring the THC and Ohmic circuits this afternoon I was still puzzled by this post. Do you mean the fuses should be in the sense lines directly next to the THCAD5 and another directly next to the 24- post on the isolated PS? Or just the opposite of that, a fuse on the gantry near the torch and another on the table near the connection point of the sense?

Also, what size/type fuses would you recommend using?

Thanks again!

The fuses are to protect the sense wires from fault currents so they
should be as close to plasma machine as possible. 1A should be fine
(It should be rate to interrupt the plasma voltage and current)

Thank you

Would this FNQ-1 fuse be adequate?
