The Excalibur Torch employs innovative design features for high efficiency performance with low maintenance and operating costs.
The Excalibur Torch features:
  • High efficiency nozzles with a choice of multi-powder ports. Powder efficiency has been measured at 99.5% recovery with a 1/8 inch (3.2mm) nozzle
  • Standard nozzles with two powder ports
  • 12 inch electrodes in 1/8 and 3/16 inch diameters
  • Self-centering electrode which does not require gas distributor
  • Fully machined construction to precise standards
  • Torch parts which are all replaceable
  • Fully sealed internal powder feed to eliminate losses and contamination
  • Quick change nozzles that do not require securing screws
  • An available heavy duty large shield

Plasma Transferred Arc Torch
Model 200 Torch

The Model 200 Plasma Powder Surfacing Torch is a low profile plasma transferred arc torch that meets Wear Technology’s standards for minimum replacement parts, optimum nozzle life, low cost parts replacement, and unsurpassed reliability. The Model 200 Torch will coat internal bore surfaces down to 3-1/2” diameters. The nozzle design provides efficient cooling for applications requiring preheat at high as 800 °F. An insulated shroud covers the service tubes to further aid torch cooling.
The Model 200 Torch features:
  • A small size (1-3/4” diameter x 2” high) allowing for surfacing of internal bores as small as 3” in diameter. Optional 24” and 36” reach models are available
  • Efficient cooling allowing for preheats as high as 800°F. The unique design promotes rapid heat dissipation contributing to maximum nozzle life
  • Precise, reliable, efficient (up to 95%) material delivery using a 4-jet powder injection system
  • Complete encapsulation of the torch’s gas and water service tubes
  • Deposition rates up to 4 lbs./hour at 150A continuous cycle
