Why does my plasma cutter keep stopping?

Why does my plasma cutter keep stopping?

The cutter nozzle has a second set of channels. These channels release a constant flow of shielding gas around the cutting area. The symptoms are often that the plasma cutter won’t initiate an arc on the metal, or the arc will start and stop erratically while you’re cutting.

How do you troubleshoot a plasma cutter?

Plasma Cutter Not Arcing ( Proved 7 Troubleshooting Methods)

1. Too high air pressure.
2. Too low air pressure.
3. Poor contact between ground wire and workpiece.
4. Torch nozzles and electrodes burn out.
5. The spark generator cannot automatically break the arc.
6. The input AC voltage is too low.
7. Others.

What could be some of the possible problems that cause bad cuts while using a plasma cutter?

Negative Cut Angle

• Misaligned torch.
• Bent or warped material.
• Worn or damaged consumables.
• Low arc voltage and/or.
• Cutting speed too low.

Why does my plasma cutter cut on an angle?

This problem can be caused by a worn nozzle, high torch standoff (arc voltage), excessive amperage, inadequate gas flow, or low speed. This problem can be caused by low torch standoff (arc voltage), inadequate amperage, excessive gas flow, or high speed.

What’s the best way to troubleshoot a plasma cutter?

At first, it’s set pretty low, right around 15 PSI. First, turn up the air pressure to about 60 or 65 PSI for 1/8-inch thick hot rolled steel. Push down the knob to make sure the pressure regulator is locked in place. Turn the amperage down to 20 amps at 60 PSI, give that a try. Then cut it at 25 amps and 30 amps and check the quality of the cut.

What happens when you remove swirl ring on plasma cutter?

When I removed the swirl ring, there is an arc. Although the arc can cut or melt through metal, it’s not the correct cutting process, because the swirl ring is required for plasma cutting. I’ve replaced all the three components- tip/nozzle, swirl ring and electrode, set the compressed air at different levels and removed the casing to check.

What kind of circuit board does a plasma cutter use?

Other similar units may include CUT40D, CUT50, CUT50D or Simadre CUT40, etc. I opened up the plasma cutter and found a burned out resistor on the bottom transformer/rectifier circuit board. The circuit board consists of four large capacitors, a transformer, some rectifier diodes, some resistors and connectors.

How to troubleshoot a Hypertherm plasma cutter torches?

Hypertherm Plasma Cutter Troubleshooting All torches need three ingredients to produce a pilot arc (plasma gas, DC Power, AC high frequency). If you are experiencing issues starting the cutter, first check the pilot arc: Raise it a few inches from the material
