Bevel for 1.2mm Stainless Steel

I tried everything, changing new comsumables, squaring the torch to the material, install a motorguard filter... but it didn't help alot. When I turned the torch around 90 degree, the bevel would change as well so I think there is something wrong with the air in the torch. I just straightened the torch coil assembly and going to have some test this afternoon. One more thing I am going to do is install a new meter at the back of the Hypertherm 45 to measure the actual psi. I have 120psi at the compressor, is it too much or should I turn down the psi to 90?

How far away is your compressor to your plasma unit? My compressor is set to 120 psi but it is outside of our shed and I have a regulator just before my plasma unit that turns the pressure down to 90 psi.

Sounds like its definitely a torch issue. I would get in contact with your Hypertherm agent and see if they have any idea of what could be the issue with the torch. How old is your unit? There might be some air line parts that are worn out. When you changed your consumables did you swap out your swirl ring?

The compressor is a few meter from the plasma cutter but there is a long coil connected between the compressor and the plasma cutter. I think it will cut the coil shorter to see any difference. The plasma unit is a few years old and the torch is couple years old. Yes, I did change the swirl ring. Does the swirl ring still stick to the torch as you take off the retaining cap to change the consumables?

Yeah I am sure the swirl ring is designed to stick to the torch when you take the retaining cap off.

I would think as long as the plasma unit is getting enough air it should function as normal as it has its own internal air regulator, well my 125 unit does, not sure about the 45 amp unit.

Does the unit show any error codes when you are cutting? If its not getting enough air or the input air pressure is too high it will display a error code.

It doesn't show the amber error light but sometimes I will see 2 green lights, 1 in the middle and 1 at the top or the bottom indicating the air pressure is a little high or a little bit low. Definitely I will put in a new regulator at the back of the plasma cutter to see how it goes. If you have any other ideas to try, please let me know.

I will do. Read through your user manual for the 45 unit and see what the machines should do if the pressure is too high or low.

On my 125 amp unit I get error codes 0-12-1 for too low air pressure and I have had 0-12-2 for too high air pressure.
