Cut50d plasma cutter. When I pull the trigger the fault light comes on and the unit will not work. I have good air pressure and voltage.

  • Scott Mar 29, 2019

    How old are the consumables in the gun? I have a Thermal Dynamics that will shut off if I accidentally damage the electrode or the cutting tip, etc.

    It's widely accepted that the torch has to "consume" certain parts that will wear out.

    I recommend spending 30 bucks or so to make sure ALL your consumable parts are replaced. Also make sure the inline air filter doesn't need a new element. Water can make it swell up and you'll need one ASAP.

There are really a lot of important details in this situation. You need a detailed analysis of the device and only after that, you can make a conclusion. Contact the service, or you can try to perform diagnostics yourself. I had a similar situation a couple of years ago. I needed to weld a crack in the suspension of my car, but the machine also didn't function. I decided that it wasn't worth it to ask for help and pay for it. So I decided to use the pro welder guide where I found all the necessary information. I was able to fix the machine and fix this crack. In addition, my work was of high quality. I think you also need to read the manual and save a lot of money not to contact the service

I have a simadre cut50D an I don't have the ground cable can I still use it?

No. Check here for the specifics of how plasma cutters work: http://home.howstuffworks.com/plasma-cutter4.htm Without a ground cable, you cannot complete a circuit, and the physical basis of how a plasma cutter works doesn't function.

Miller 375 x-treme fires about 30 seconds then stops it doesn't stay running, no trouble lights...

Have you watched to see if the pressure light comes on right before shutdown? If so you may need to add a tank right next to the torch base to address the pressure drop assuming your air source is able to deliver adequate volume to the cutter continuously and you currently have more than 25 feet of hose between cutter and compressor. It might not hurt to check the internal filter as well.

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.

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.

Spectrum 2050 plasma cutter will not arc

Possible failure of the trigger switch and or the cable back to the unit. Use an ophmmeter to check that the trigger and cable are good,

Then with the ohmmeter check the continuityu of the cable to the electrodes,

Connectors are always suspect.

These are starting ponts to check.

Not getting a spark when I pull the trigger

Try checking the front Panel and Internal fuses, as well as the thermal overload.

This could happen when you exceed the duty cycle.

eg: 20% Duty Cycle In a period of 10 Minutes, 2 minutes cutting, 8 minutes not.


Best of luck

Thermal dynamics cutmaster 50 2004 yr.

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.
