A Passion for PTA

Kennametal Stellite’s ingenuity and passion for PTA performance is showcased in our portfolio of high quality torches. Our portfolio of torches is designed with efficiency and flexibility in mind. And allows users optimize for their specific application.

Kennametal maintains a wide portfolio of PTA torches for a variety of applications. Ask our engineers which one is right for you.

Excalibur II & Excalibur Heacy Duty II

The Excalibur II torch is the pinnacle in PTA welding performance and technology. Its innovative design allows high efficiency hardfacing operations with low maintenance and operating costs. The Excalibur II torch features include:

  • High efficiency nozzles with a choice of multi-powder ports. Powder efficiency measured at 99.5% recovery with a 1/8" (3.2mm) nozzle
  • Two powder ports
  • 12" electrodes in 1/8" and 3/16" diameters
  • Self-centering electrode
  • Fully sealed internal powder feed to eliminate losses and contamination
  • Replaceable torch parts
  • Fully machined construction to precise standards
  • Quick change nozzles do not require securing screws

Model 600

The Model 600 torch can be installed on almost any STARWELD® PTA system.  This general purpose, water-cooled, hardfacing torch is used for numerous applications. The Model 600 is only about 1.5 inches in diameter making it easy to get into tight spots:

  • Orifice diameter available in 3/32”, 1/8”, 5/32” and 3/16”
  • Better arc control
  • Connection points that are color-coded to facilitate installation
  • Removable powder tubes
  • Self-centering electrode
  • Extended nozzle for hard-to-reach corner areas

Model 200 ID

The Model 200ID torch is a low profile plasma transferred arc torch that will coat internal bore surfaces down to 3-1/2” diameters. It’s nozzle is designed to provides efficient cooling for applications requiring preheat at high as 800 °F.

  • Available in 12”, 24” and 36” lengths
  • Small profile (1-3/4” diameter x 2” high) allowing surfacing of internal bores as small as 3-1/2” in diameter
  • Designed for rapid heat dissipation allowing for maximum nozzle life
  • Precise, reliable, efficient (up to 95%) material delivery using a 4-port powder injection system
  • Complete encapsulation of the torch’s gas and water service tubes
  • Deposition rates up to 4 lbs/hr at 150A continuous cycle
