Small and extremely efficient, it is one of the most portable single-phase inverter cutting machines on the market today. Power supplies have a 3-year warranty and torches a 1-year warranty.Įnvironmental stewardship is a core value of Hypertherm. The new CUT 40 Air Plasma machine is the latest offering in inverter technology. Cut 40 Plasma Cutter Circuit Diagram Manual TIG Processīut a Plasma Jet can be produced by placing a Tungsten electrode centrally within a water-cooled constricted copper nozzle.356 mm (14.0') D 168 mm (6.6') W 305 mm (12.0') HĬSA-certified for use in the Americas and Asia, except ChinaĬE, C-Tick, CU/GOST, Ukr, and Serbian - for use in Europe, Australia, Belarus, Kazakhstan, Russia, Serbia, Ukraine, and other countries where accepted. Gas is fed into the nozzle, and, when an arc is struck between the tungsten electrode and the nozzle, the gas is ionised in its passage through the arc.īoth work and nozzle are connected to the anode, the tungsten electrode to the cathode of a D.C. So a further supply of argon is fed to the outer shielding nozzle to protect the weld.Ī high-frequency unit, fed from a separate source from the mains supply, initiates the pilot arc.

The flow of cooler gas through these squeezes the circular pattern of the jet into oval form giving a narrower heat-affected zone and increased welding speed (Fig.įor copper, nickel and their alloys argon is used for thinner sections.Īrgon and helium is used in the melt-in welding of thinner sections and helium for orifice and shielding gas for metals over 3 mm thick.
