D/F Water-Cooled Semi-Automatic MIG Hand-Held Pistol Grip Gun Model NC-21/HT-21

With more than 44 years of aluminum and steel trailer welding, D/F Machine Specialties Water-Cooled Semi Automatic "MIG" Pistol Grip Gun Model NC-21/HT-21 has been welding trailers from specific use trailers such as aluminum flatbeds, dump trailers, horse trailers, livestock trailers, bumper pull trailers, tilt deck and other truck bodies, aluminum utility trailers, landscape trailers, open & ramp trailers, enclosed snowmobile trailers, aluminum ATV trailers, aluminum motorcycle trailers, and car hauler trailers to large custom trailers such as enclosed aluminum cargo trailers, enclosed race car trailers, concession trailers, deck over equipment trailers and mobile professional trailers for use as medical labs, libraries, and teaching facilities. The D/F pistol gun is also welding Stainless Steel custom built tank trailers, specialty transport trailers including liquid, dry bulk, oilfield, construction, platform, specialized, towing and defense trailers and dry freight vans, pups/doubles, refrigerated vans, and platform trailers.

Remember the Great Linde ST-5 Torch (part no. 46V34) that was used exclusively for gas metal arc (MIG) spot welding of aluminum and hard wires? Very similar in design to the Linde ST-5 and ESAB ST-21 but with improvements and new features, and proven to be a superior replacement alternative, the D/F Water-Cooled handheld 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 DF 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 1/8" 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 pistol grip 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.

Each D/F gun is fully assembled and ready to install. In order to make the installation complete, the code number, wire size, make/model (Lincoln wire feeders, Miller wire feeders, ESAB wire feeders, & EURO Quick-Disconnect wire feeders), and inlet as needed must be specified when ordering. If special welding tools or accessories other than those listed previously are required, please consult with the factory. Get the Right Feeder Adapter Connection to Fit Your "MIG" Wire Feeder.
