How does plasma torch height control work?

The torch height control uses arc voltage to maintain a consistent distance from the plate while the torch is cutting. This allows the system to maintain proper torch height regardless of variations in the material, or flatness of the cutting bed.

What is Pierce height in plasma?

1/8”
Ideally, the pierce height should be 1/8” off of the material surface you are cutting, to allow the plasma to penetrate, but more importantly when using Arc Voltage Height Control systems, to help maintain the height of the torch tip while the voltage is being read, and maintained.

Is a plasma torch actually plasma?

The basic plasma cutting process involves creating an electrical channel of superheated, electrically ionized gas i.e. plasma from the plasma cutter itself, through the workpiece to be cut, thus forming a completed electric circuit back to the plasma cutter through a grounding clamp.

How is an arc created in a plasma system?

The spark ionizes the plasma gas, allowing it to become electrically conductive and producing a low-resistance current path between the electrode and nozzle. Along this current path, an initial, low-energy arc—i.e., the pilot arc—forms as energy flows and discharges between the two components.

Can a plasma cutter cut wood?

Virtually any metal can be plasma cut including steel, stainless steel, aluminum, brass, copper, etc. Plastics and wood are not electrically conductive and cannot be plasma cut. However, you can use a rotary saw, router, or other tool if you want to cut these materials in the PlasmaCAM machine.

Can a plasma cutter cut aluminum?

Plasma cutting can be performed on any type of conductive metal – mild steel, aluminum and stainless are some examples. Plasma cutting, however, does not rely on oxidation to work, and thus it can cut aluminum, stainless and any other conductive material.

Can a plasma cutter Weld?

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.

How do plasma torches work?

Plasma cutters work by sending an electric arc through a gas that is passing through a constricted opening. The gas can be shop air, nitrogen, argon, oxygen. This high speed gas cuts through the molten metal. The gas is also directed around the perimeter of the cutting area to shield the cut.

How thick can a 50 amp plasma cutter cut?

Excellent Air Plasma Cutter: The Cut-50 Plasma Cutter can easily cut up to 0.55”(14 mm) metal under maximum output with ultimate portability weighing only 21.56 lbs.

Can you cut cast iron with plasma cutter?

The more energy added via the plasma cutter, the hotter the plasma arc becomes, providing more cutting capacity and efficiency. One of plasma’s greatest advantages is its ability to cut non-ferrous metals such as aluminum, stainless steel and cast iron, materials that are becoming more common in many applications.

What can’t you cut with a plasma cutter?

Tungsten is the hardest to cut and needs professional equipment to cut it properly. Other materials that cannot be cut include glass, concrete, and ceramics. These materials are non-conductive and are used to insulate electrical products.

What is torch height control in plasma CNC?

THC stands for Torch Height Control. For your plasma CNC application you can use PlanetCNC motion control system together with PlanetCNC torch height controller. Torch height controller consists of torch height controller and torch height sensor device. Torch height sensor device measures arc voltage.

How to choose the right plasma torch?

In plasma, you want a rigid gantry that does not have flex and is true and square to maintain accuracy. For the plasma torch to provide the best quality cut, you need to maintain cut height and the correct speed for the material and power.

What is tortorch height controller?

Torch height controller consists of torch height controller and torch height sensor device. Torch height sensor device measures arc voltage. Bigger the distance between the plasma torch and material higher the voltage and vice versa. So based on the measured voltage value we can maintain constant height of plasma torch above the material.

What is THC device in plasma CNC?

This is usually solved with THC device. THC stands for Torch Height Control. For your plasma CNC application you can use PlanetCNC motion control system together with PlanetCNC torch height controller. Torch height controller consists of torch height controller and torch height sensor device.
