D/F Water-Cooled "TIG" Pistol Spot GunThe D/F Model MTS Water-Cooled "TIG" Pistol Spot Gun is for use in semi-automatic applications of the Tungsten Inert Arc Process. 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 orintermittent basis. There are four (4) collets available for use with this machine barrel, the sizes are 1/16", 3/32", 1/8", and 5/32". The singular collet design provides clamping pressure when the collet is securely fastened.
The D/F Machine Specialties Water-Cooled "TIG" Pistol Spot Guns will spot weld such materials as mild steel, stainless steel, monel, and inconel in thickness of 1/8" (3.2mm) or less from one side only. The "TIG" spot weld process is not suitable for aluminum, galvanized, or coated materials.
The "TIG" spot weld process uses a conventional "TIG" welding machine equipped with a spot timer and high frequency arc starting. The spot gun is connected to the D/F Machine Specialties Utility Station, which is then connected to the welding machine. The spot guns are simple to use and are constructed of heavy duty, durable long lasting materials. Replaceable direct spotting nozzles for 90 degree and flat surfaces are constructed of hard tempered copper and are available for tracking inside or outside corners, and butt and lap joints.
