Miller JB000000

The Miller JB000000 is a plasma cutter designed for cutting low and high alloy steels, aluminum, copper, and brasses. It uses a standard Gas Tungsten-Arc Welding (GTAW) power source with a minimum open-circuit voltage of 70 volts and a maximum open-circuit voltage of 100 volts. No additional equipment is required.

The plasma cutting process involves striking an arc between a cathode (electrode) and an anode (constriction nozzle) using a high-frequency impulse. A regulated flow of gas (Argon, Argon - Hydrogen mixtures) is introduced into the arc cavity, which ionizes and dissociates under the heat of the arc. The expanding gas and a stream of high-energy electrons are forced through the constricted opening of the tip, creating a plasma jet.
