SOURCE: plazma cutter/no arc

The Cutmaster 50 used two different CD "Capacitor Discharge" Boards. The only ones I have seen a lot of issues with were the smaller ones that are 3.5" X 4"

I have worked on several of the them over the last few months. Even though you might see a spark at the spark gap on the board it might not be sufficient to create a pilot arc.

If your air pressure and so forth are correct your issue is most likely the two white capacitors on the CD board.

My pro cut 55 Lincoln plasma cutter sounds like a machine gun when I strike it and put it to the metal. It cuts holes when you hold the trigger down and try and make a continous cut. new air dryer

"Remember, they are a drag machine up to about 3/8" thick material. Keep the power down as low as possible for the material being cut. Keep the right air filters on to supply clean air. Keep the air pressure between 60 (min or it will shut down) and 70 for most applications (more is not better-just like oxygen on the torch or air to an air-arc).

Also, check that the air hose hasn't come loose from the gun.
That was Brian's problem from YouTube (

Your plasma has a start arc pilot inside the machine, this one must be faulty, check your owner's manual and request the part to your nearest welding store. It is easy to replace.

Shuts on on safety ,,almost immediatley

Check that the tip is assembled correctly.If is not in properly, it will not arc. Second, check air pressure switch. Sometimes they become stuck from corrosion due to moisture in the air. Test the operation with a tester

Check compressed air pressure is in limits otherwise unit will cut out. Try adjusting the pressure up. also make sure the supply pressure is correct as it may not be your plasma cutter at fault.
