Why will my plasma cutter not arc?

Why will my plasma cutter not arc?

The compressor is short of air. The pressure adjustment of air conditioning valve of the plasma cutting machine is too low. There is oil pollution in the electromagnetic valve. The air channel is obstructed.

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.

Why does my plasma cutter sputter?

One common plasma nozzle problem occurs when the orifice becomes blocked, sometimes due to molten material contacting the tip and then cooling down and hardening there, altering the plasma flow. An off-center stream will steadily wear down the orifice.

Can you arc weld with a plasma cutter?

With the right torch design, a nitrogen-water injection, less expensive than other gases, can work well when plasma cutting aluminum and stainless material for subsequent welding. The process involves an electrode surrounded by nitrogen, which is heated by an electric arc to form the plasma.

What air pressure is required for plasma cutting?

between 55 to 70 psi
For the majority of the Everlast product line, air pressure required to operate the torches is anywhere between 55 to 70 psi. Low amperage cuts will require less air pressure for more stable operation, sometimes down to 45 psi or so, or the arc will be blown out.

How can I improve the quality of my plasma cut?

How to improve your CNC Plasma Cut Quality (tips & tricks)

  1. Air Quality – Having clean, dry, oil free air is a must.
  2. Torch Height – Both for pierce and cut, ensuring that the machine maintains the correct height at all times is critical.
  3. Cut Direction – Ya that’s a thing.

How do you make a plasma arc?

In plasma arc machining a continuous arc is generated between a cathode and an anode. A gas is introduced around the cathode and flows through the anode. The temperature, in the narrow orifice around the cathode, reaches 28,000 °C, which is enough to produce a high-temperature plasma arc.

Can you plasma cut tungsten carbide?

It’s sintered tungsten carbide that is formed, not melted or forged. Sheets are available for certain bearings but it can’t be cut with a plasma. Normally, carbide tools are solid carbide or brazed carbide ‘tipped’ or inserts of carbide in tools forged and machined from high strength steel.
