Plasma Cutting Apparatus

In manual plasma cutting in the installation kit includes torch, plasma torch (plasma cutter) and a power source (plasma cutting machine). Plasma-forming gas may come from the built-in compressor unit (compressed air), on line or tank (compressed air, nitrogen, etc.).

The vast majority of power supplies for plasma cutting is working on a direct current straight polarity (for DC plasma torches, the highest efficiency of power). Alternating current is used in some cases, eg for cutting aluminum and its alloys.

Plasma Cutting Machines to ensure maximum stability of the operating current for the voltage fluctuations. In this regard, they have a steep or vertical external current-voltage characteristic. Steep external characteristic, shown in the figure below, is formed by the use of choke saturation of the thyristor control circuits and circuits operating on the principle of resonance voltage three-phase circuits, so for plasma cutting in most cases using special straighteners.

Sources (rectifiers) Plasma divided into transformer and inverter. Transformer (traditional) units are so called due to their use in low-frequency transformers. They have a much greater mass and size, but it may also have higher power. Such devices are used for mechanized and manual cutting of different thicknesses.

Inverter plasma cutters have small weight and dimensions (because they do not apply heavier low-frequency transformers), low energy consumption, but at the same time, they are limited by the maximum power (current, typically less than 70-100 A). They are usually used for cutting relatively small thickness.
