This Machine does Plasma Transferred Arc Welding process designed for general purpose, multi-faceted, hard face production welding.
WHAT IS PLASMA TRANSFERRED ARC WELDING?
Plasma Transferred Arc (PTA) welding is a mechanized process that applies a fully fused metal deposit. The process uses a constricted arc and powdered filler metal. Figure 1-1 illustrates, schematically, a typical PTA torch. In a typical PTA Torch, metal powder is carried from a powder feeder to the torch in an argon, or special gas stream. Once in the torch, the powder is directed into the arc flame where it is melted and fusion bonded to the work piece. Energy for the transferred arc is provided by a direct current (DC) power source connected between the tungsten electrode and the work piece. A second DC power source connected between the tungsten electrode and the outer wall of the torch provides a pilot arc that initiates the transferred arc and provides supplemental heat. Argon passes through a gas diffuser, providing a blanket of shielding gas in and around the arc zone. An overlay produced by the PTA process has similar metallurgical characteristics to the overlay produced by the gas shielded arc process or by submerged arc welding. Deposits are homogeneous and fusion bonded to the work piece. The heat distribution provided by the constricted arc, coupled with the powder's buffering action, produces overlays with dilution levels approaching those obtained with oxy-acetylene surfacing. (Dilution, usually expressed as a percentage, is the degree of mixture between the deposit and the base metal.) PTA deposition rates exceed those obtained with the gas tungsten arc (GTA) process while maintaining less than 10% dilution. Fused deposits as thin as 0.030" (0.75 mm) or as thick as .187". (4.7 mm) can be obtained in a single pass. The PTA process produces smooth deposits of controlled thickness resulting in reduced material and finishing costs.

The Powder Feeder (KK-2) is typically located on the top left side of the cross feed beam carriage. The powder feed rate is infinitely variable and adjusted from the control pendant. Carrier gas flow control is located on the front of the console. The powder feeder is fitted with a low powder sensor. The sensor activates a warning indicator on the control pendant.
