Used Plasma Cutters For Sale

A Staple for Fabrication

Plasma machines produce an electronic channel by passing a gas through a constricted opening inside a torch. An electric arc is generated from the external power supply, which is when the gas is introduced. This forms a “plasma jet” that can reach temperatures of up to 40,000° F. The plasma cutters for sale here can use a variety of gases, including oxygen, nitrogen, and combinations of argon/hydrogen/nitrogen.

What are the main components of these fabrication machines?

• Plasma Torch: This component provides proper alignment and cooling of the consumables. The main consumable parts required for plasma generation are the swirl ring, nozzle, and electrode. A shielding cap can improve cutting quality.
• Arc Starting Console: The arc starting console circuit produces an AC voltage of about five thousand VAC at 2 MHz. This generates a spark inside the plasma torch, thereby creating the plasma arc.
• Power Supply: The power supply converts single or three-phase AC line voltage into a smooth, constant DC voltage. The DC voltage maintains the plasma arc throughout the cutting process.

Take Your Pick!

There are generally two main types of used plasma tables for sale online: conventional and precision.

Conventional: A conventional plasma cutter for sale uses shop air as the plasma gas. The nozzle’s orifice defines the shape of the plasma arc. All handheld systems utilize conventional plasma.

Precision: A precision plasma system has a high current density and is designed to produce the sharpest-quality cuts. Multiple gases, such as oxygen, nitrogen, and a hydrogen/nitrogen/argon combination, are used as the plasma gas.
