As the most popular plasma spray gun, we offer a copy of the US SG-100 spray gun. The main gas of the gun is argon or nitrogen, and the auxiliary gas is hydrogen. The spray gun provides the following accessories: nozzle, powder tube and powder rack, water cable, electrode head, insulator, sealing ring, special tools, etc. The gun is used in production thermal spraying operations and can work continuously for long periods of time. The spray gun is today's global users widely used and proved to be the most stable and reliable universal plasma spray gun, the spray gun has hundreds of customers in China, and mature application in the thermal spray industry.
Working current: 100 ~ 1000A, working voltage: Ar+H2 30 ~ 80V, N2+H2 37 ~ 80V.
The gun is used in production thermal spraying operations with a maximum stable output power of more than 50KW.
Plasma spraying is carried out by plasma arc, ion arc is a compressed arc, compared with the free arc, its arc column is small, the current density.
The gun uses a non-transfer arc: a plasma arc generated between the cathode and the nozzle. In this case, the positive electrode is connected to the nozzle, the workpiece is not charged, and an arc is generated between the cathode and the inner wall of the nozzle, and the working gas is heated through the arc between the cathode and the nozzle, causing all or part of the ionization, and then emitted by the nozzle to form a plasma flame (or plasma jet).

The powder delivery design of the SG-100 gun allows it to deliver powder at low pressure in the powder feeder, unlike some guns that require a high pressure powder feeder, which improves process stability.
