Bevel for 1.2mm Stainless Steel

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.
