We have a Hyperrtherm HT400 power source on a MG table with a Burny 5 controller using shop air for cutting. Nesting software is Hypertherm Pro-nest.

The system will cut and then stop cutting for +-3 in, this happens in both directions in various positions on the table The "GO" button goes out when it happens, By pressing "GO" it fires up and will cutting again. It starts immediately and will run fine for +- 12-48" before it happens again. It almost look like a bad control wire that looses contact ?

Can it be a bad torch that effects feedback signal ?

Any advise will help.

Thanks.
