D/F Water-Cooled "MIG" Pistol Grip Gun Model NC-21/HT-21

D/F Water-Cooled "MIG" Pistol Grip Gun Model NC-21/HT-21

The D/F Water-Cooled pistol grip MIG gun offers a design with complete interchangeability of nozzle lengths for manual MIG welding of Aluminum and Stainless Steel, using .030" through 7/64" diameter wires. The torch may be adapted to spot or continuous fusion welding, and is ideal for welding with 3/64" and 1/16" AL & SS wire.

Very similar in design to the Linde/ESAB ST-21 but with improvements and new features, and proven to be a superior replacement alternative, the D/F Water-Cooled pistol grip MIG gun is a rugged all purpose, water-cooled, manual "MIG" welding torch designed to operate at welding currents up to 600 amperes continuous duty using all types of shielding gases. The torch utilizes a pistol grip design for convenient start-stop welding control and easy handling, and its in-line type construction allows all service lines to enter through the torch barrel. The D/F Pistol is intended for use with all wire feeders which have provision for water cooling and will handle all types of welding wires from .035" diameter through 7/64" diameter including flux cored wire, 3/64" AL through 3/32" Aluminum wire.

To provide maximum resistance to the abuses of day to day service, the torch is of heavy duty construction with all metal parts well insulated from current carrying members. The in-line body and pistol grip handle allow the D/F Pistol to be used in a variety of applications with easy maneuverability and comfortable operation. To facilitate maneuverability, all service lines are internally connected to the torch body and exit from the rear of the torch barrel. The torch can use either threaded contact tips or slip-in contact tubes which are secured with a collet nut supplied with the torch. The contact tip can be quickly and easily replaced by unscrewing the metal nozzle and collet nut, and removing the tip. Six water-cooled metal nozzles with different lengths and different I.D./O.D. are available for use with the D/F Pistol for continuous fusion welding and for spot welding applications. The water-cooling requirements for the D/F Pistol are described below.
