Its possible the selector switch between mma, plasma and Tig is bad, also, try to keep the plasma air pressure between 45 and 55 PSI, too much air will destabilize the plasma and prevent you from initiating the arc.

Could be as simple as having the ground cable connection placed into the wrong port on the front of the machine. Foot peddle/machine selection switch in peddle mode instead of machine mode? Internally it could be high frequency spark leakage or failed HF circuitry. These are the most common causes of spark failure. Oh and be sure you have good consumables and they are installed correctly. Air pressure leaving the torch head should be around 70 psi.

The gas light come on and flashes and wont cut. I have changed all the nozzels on the torch and still nothing?


Hi:

Gas light goes on when you have an air flow or pressure problem. Do you have enough pressure? you will need at least 120 psi at the compressor and 75psi at the plasma machine. Do you have enough flow? You will need 20 SCFH and a 30 gallon compressor reserve tank.

Let me know if this help. Please vote.

Only cuts for 3 seconds, device still on


Possibly an internal short in the torch tip... the expendable components failing in the tip will cause the sensors in the machine to register a "no cut" or "free air arc" state and kill the power to the tip to prevent damage to the unit. Replace the tip components and double check the grounds connections.

Plasma cutter problem - is cutting on beveled angle.


worked on units for several years,my first thought was torch consumables,then torch itself,so here we go.make sure all the consumables are exact for the torch,make sure all parts are brand new,(all parts,that way we can elimenate that part of trouble shooting).check that the ground is tight on the unit and work peice.When you bought the new torch head did you also buy the lead to the head?If not possible that could be the problem.

Check contacts in tip and be sure it is all lubed correctly. If you have good air pressure and flow it should arc after pulling the trigger for about 2-3 seconds.
