What consumables does a plasma cutter use?
Plasma cutting torch consumables include: a swirl ring, electrode, nozzle, retaining cap, and shield cap.
- Swirl ring. This is a small component inside the torch that swirls the gas surrounding the plasma arc.
- Electrode.
- Nozzle.
- Retaining Cap.
- Shield Cap.
How long do consumables last in a plasma cutter?
about 1 to 3 hours
Typical life time of a set of consumable should last about 1 to 3 hours for about 120 A of mechanized cutting, it’s in function of the job. Cutting at lower current may gets longer consumable life.
What are Hypertherm consumables made of?
It is comprised of a copper holder that contains an emissive element of hafnium or tungsten— metals with high melting points that will sustain an arc.
Can you stick weld with a plasma cutter?
The major difference between a plasma cutter and a multi-process machine is this: the plasma cutter will have one function, cutting. The multi-process machine will have several functions, usually stick welding and TIG welding in addition to plasma cutting.
When should I replace my plasma cutter consumables?
As you use the electrode, the hafnium/tungsten becomes molten and pieces of it start to blow out through the nozzle as you cut. It develops a pit at the front of the electrode. Once that pit depth is over 1⁄32, it’s time to change the consumable.
What gas do I need for plasma cutter?
Gas is needed for a plasma cutter in order for it to work and create the plasma. As mentioned, the most popular gases to use are oxygen, nitrogen or argon. Some plasma cutter systems include multi-gas features so a variety of gases can be used for different applications.
What kind of gas is used for plasma cutting?
Nitrogen
Nitrogen is often used for higher current plasma systems and for cutting materials up to 3 inches thick. It produces excellent quality cuts on most materials. Oxygen is used when the highest quality mechanized cuts are desired on carbon steel up to 1 -1/4 inch thick. The cut face is smooth, and dross is easy to remove.
What gas is most commonly used for manual plasma arc cutting?
Argon gas is used when plasma marking (a whole other subject). A mixture of Argon and Hydrogen is often used when cutting thicker Stainless Steel or Aluminum. Some people use a mixture of Hydrogen and Nitrogen, or Methane and Nitrogen when cutting thinner Stainless Steel.
What are Pac torch electrodes made of?
copper
The electrode is usually made of copper, but with a metal insert at the point where the arc attaches.
Can you plasma weld aluminum?
Plasma cutting aluminum can create perfect welds. By using such a cutter, you can keep the surface of the metal outside the welding area moderately cool. Also, it helps prevent the distortion or paint damage that usually comes with flame cutters. Plasma cutters accurately and quickly weld aluminum workpieces together.
Can you use compressed air on a plasma cutter?
Compressed Air The most commonly used plasma cutter gas type is air. Highly versatile and inexpensive, compressed air works well for lower current cutting and on most metals—mild steel, stainless steel, and aluminum–from gauge sizes to one-inch thickness.
What are the five common replaceable torch components?
For most manual plasma cutting systems, five different components comprise the torch consumables—the shield, retaining cap, nozzle, electrode, and swirl ring.
