The Model TM-500-B (Bottom Load) Water-Cooled "TIG" Machine Torch is for use in Semi-automatic Machine or Robotic TIG applications.

A unique feature of this Water-Cooled "TIG" barrel is that the nozzle assembly water chamber and inner body water chamber are serially connected to each other, thus completely eliminating the need for gaskets or "O" rings in the water passage system.

Maximum current rating with thoriated tungsten electrodes is 500 amperes DC, straight polarity; and 300 amperes AC, high frequency may be superimposed over standard current on a continuous or intermittent basis. There are five (5) collets available for use with this machine barrel, the sizes are .040", 1/16", 3/32", 1/8",  and 5/32". The singular collet design provides clamping pressure when the collet is securely fastened on the tungsten.
