|D/F Water-Cooled-to-the-Tip MIG Robotic Torches|
D/F Water-Cooled-to-the-Tip 5" & 8" Series A High-Capacity Machine Torches
The fully Water-Cooled-to-the-Tip Robotic MIG (GMAW) Torch Models NCM-W/C-T & HTM-W/C-T are applied to a Remote Mount Docking Spool® for high current single arc welding. These robotic torches are fully water cooled internally and externally. The internal body of the torch is water cooled, thus putting the water cooling on the tip. This has increased tip life up to 14 times longer. Also, because the water cooling is on the tip, this enables customers to use our less expensive 122 slip-in copper tips for many applications. The exterior water cooled nozzle is internally water cooled as well. There are no bulky external water lines in the way leading down getting caught or getting damaged by heat. Because of the superior internal and external water cooling of this torch, you can run the full range of wires from .030"-1/8", whether your job is aluminum, steel, stainless steel, hard, cored, flux cored, stellite or inconel wire, whether your job has 1000 degree preheat, high deposition or continuous duty cycles, this is the torch. Very similar in design to the Linde ST-12 and Guild ST-12 but with improvements and new features, the D/F Machine Water-Cooled-to-the-Tip Robotic Torches are designed to provide long trouble-free service. These Automatic Water-Cooled-to-the-Tip Torches are available in 5" and 8" lengths. Each length is available with our standard size nozzles (1.125"), and our high capacity (series A) nozzles (1.445") for more gas coverage. You can switch between the standard nozzles and high capacity nozzles if you have the correct inner parts for each. 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 Docking Spool®, and a Water-Cooled Nozzle. The 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.
W/C Tip D/F Machine Specialties torches are standard equipped with 1 water/out & power cable are rated at 650 amps (continuous duty cycles). These ratings are, however, dictated by the contact tip. The NCM (slip-in) series of contact tips is rated up to 450 amps (continuous duty cycles). If your welding application requires amperages above 450, you must change to the Heavy duty threaded CrZr (chromium zirconium) series of contact tips.
These automatic machine welding assemblies are designated by torch models. The model NCM (slip-in contact tip) has a current capacity 450 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 650 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.
W/C Tip model torches can also be retrofit to have 2 water/out & power cables increasing the continuous duty cycle rating to 850 amps. These amperages require the use of the HTM or threaded series of chromium zirconium (CrZr) current tips.
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.

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, the D/F Machine robotic guns (Water-Cooled-to-the-Tip Torches) are designed to provide long trouble-free service.
