D/F Water-Cooled-to-the-Tip Robotic Torches

D/F Water-Cooled-to-the-Tip 5" & 8" Series-A High-Capacity Machine Torches

The fully Water-Cooled-to-the-Tip MIG (GMAW) Models NCM-W/C-T & HTM-W/C-T Series-A Machine Torches are applied to a Remote Mount DOCKING SPOOL for high current single arc welding. Very similar in design to the Linde ST-12 and Guild ST-12 but with improvements and new features, and proven to be a superior replacement alternative for the Lincoln Electric K148A & K148B Positive Contact Assemblies, the D/F Machine Water-Cooled-to-the-Tip Robotic Torches are designed to provide long trouble-free service. With the various models available, a contact assembly selection may be made to suit individual robot torch requirements.

The Remote Mount fully Water-Cooled-to-the-Tip DOCKING SPOOL® accommodates two (2) Water Cooled Nozzle Assemblies. This arrangement is readily adaptable to Dedicated or Automatic Welding applications such as the Lincoln NA-3, NA-4 & NA-5. The equipment consists of four (4) basic components: a utility station, an intermediate utilities combination assembly, a High Deposition (H.D.) DOCKING SPOOL®, and a Water Cooled Nozzle. The H.D. DOCKING SPOOL® is the principal component in this welding equipment arrangement. It accepts the utilities at the top end of the Spool and provides a means of accepting the water cooled nozzle at the lower end with superior water cooling. Several features important to a welding system are provided. Incorporated within the water channels of the DOCKING SPOOL® are check valves which provide a means of retaining residual water in the lines when the nozzle assembly is removed from the DOCKING SPOOL®. In addition a POSIT® Ring is provided at the upper end of the DOCKING SPOOL® which allows positive location in a Mounting Bracket to maintain dimensional stability.

The W/C Tip Torches can run the complete line of D/F standard size C122 DHP contact tips and the complete line of D/F standard size CrZr (chromium zirconium) long-life contact tips, as well as any custom current tip configuration you may need. .030" (.8mm), .035" (.9mm), .045" (1.2mm), .052" (1.4mm), 1/16" (1.6mm), 3/64" (1.2mm), 5/64" (2mm), 3/32" (2.4mm), 1/8" (3.2mm) and other diameters.

These welding assemblies are designated by Torch Models. The Model NCM (slip-in Contact Tip) has a current capacity 750 amps in argon shielding. Like the ESAB ST-12, these accommodate slip-in current tips fastened by a collet action nut. The wire diameter range with hard wire is .030"-1/16", cored wire .035"-1/8", and aluminum wire range of .035"-3/32".

The Torch Model HTM (Threaded Contact Tip) has a current capacity range of 850 amperes. Rating will be contingent on the combination of current tip and shielding gas to be used. The Model HTM employs threaded CrZr (chromium zirconium copper) current tips and will accommodate .030" - 1/16" hard wire, .035" – 1/8" cored wire and 3/64" - 3/32" aluminum wires.

In some instances C122 DHP is adequate, but for stainless steel and stiff, high column strength or abrasive wires such as Flux cored / Metal cored, CrZr is the correct choice. D/F Machine Specialties can increase several key characteristics creating a higher-quality consumable with increased conductivity, even higher softening temperature and improved hardness. This means a reduction in "arc start failures" and increased tip life. Copper chromium zirconium (CuCrZr) contact tips increase productivity.

Each D/F Automatic Welding Torch head is fully assembled and ready to install. In order to make the installation complete, the code number, wire size, make/model Automated Welding System (Thermadyne Thermal Arc Wire Feeders, Lincoln wire feeders, Miller wire feeders, Linde/ESAB 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.

D/F Water-Cooled-to-the-Tip 5" & 8" Robotic Torches

The fully Water-Cooled-to-the-Tip Models NCM-W/C-T & HTM-W/C-T Remote Mount Robotic Machine Torches offer the same features as those described for the Machine Barrels above. These torches feature the 1.125" smaller O.D. water-cooled nozzle for hard-to-reach, limited access areas. Very similar in design to the Union Carbide Linde/ESAB ST-12 and Guild ST-12 but with improvements and new features, and proven to be a superior replacement alternative for the Lincoln Electric K148A & K148B, the D/F Machine Robotic Guns (Water-Cooled-to-the-Tip Positive Contact assembly) are designed to provide long trouble-free service.

The Remote Mount fully Water-Cooled-to-the-Tip DOCKING SPOOL® accommodates two (2) Water Cooled Nozzle Assemblies. This arrangement is readily adaptable to Dedicated or Automatic Welding applications such as the Lincoln Electric NA3, NA4, NA5, NA5R, Power Feed 10, LF72, LF74 Automatic wire feeders, Miller series power pins, ESAB, Euro and Tweco #4.
