Robust Nozzle With Firm And Strong Plasma Transferred Arc

The copper nozzle is the core parts of the PTA welding torch. And here is a pore of powder feeding inside of the nozzle that would delivery the powder to plasma arc without any intervention to complete the process of powder cladding.

Further more, here is a groove ofcirculating cooling water on the nozzle for PTA welding torch, which would make it cooling virtually and the temperature of wall of the pore low, meanwhile, which the more close to, the gas with the pressure coming into the chamber of torch, the lower the ionization. The cool gas sticking to the wall almost is unionized to turn into neutral gas which it is formed a impartial gas layer of solution and thermal shield between electric arc and pore wall. At this time, the electric arc current is compulsed to the centre place where the gas ionized is severe. The shrinkable section of electric arc has increased the electric density and it would form the heat compression effect and the ion arc accomplish contraction further.

The composed substance is copper which is endurable. Mostly, its life cycle is about two month under the normal working condition.
