D/F Quick Disconnect Automatic MIG Water-Cooled Curved or Straight Machine Torches

Overview

The versatile Water-Cooled Machine Torch models NCC/LRN, HTC/LRN, NCC/N, & HTC/N can be used for a wide range of applications. The machine barrels may be applied to either a remote or direct mount Docking Spools®. With the various angles (22°, 35°, 45°, 60° and 90°) and lengths available (Long Reach 12.5" and Short 5"), a selection may be made to suit individual requirements.

The versatile D/F quick change Water-Cooled Automatic Torch models NCM/LRN, HTM/LRN, NCM/N, & HTM/N can be used for a wide range of automatic applications. With the various angles and lengths available, a selection may be made to suit individual automation requirements.

The composite modular design of the rugged, yet flexible, quick-disconnect model LRN (Long Reach 10" composite water-cooled nozzle) and the model N (short 5" composite water-cooled nozzle) torches allow the user to quickly change the swanneck (gooseneck) or cable assembly while maintaining tool center point, assuring accurate repeatability and continuous precision welding. These D/F automatic torches have a compact, stainless steel, water-cooled nozzle designed specifically to withstand unusually large amounts of reflected heat build-up and prolonged duty cycles. Water circulates internally through the docking spool to the nozzle and the tip, keeping the torches running cooler, and thus the torch and consumables last longer. Mounting is easy by directly plugging in the torch to any wire feeder with one of the many different wire feeder adapters. In the event that a component has to be adjusted or replaced, the docking spool makes this torch entirely serviceable and easy to repair or replace in seconds.

These welding assemblies are designated by torch models. The models NCM/LRN & NCM/N (slip-in contact tip) have a current capacity 500 amps in argon shielding. 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 models HTM/LRN & HTM/N (threaded contact tip) have a current capacity range of up to 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.

Standard assemblies have torch necks (water-cooled nozzles) that are either straight or bent at 22°, 35°, 45°, 60° or 90°, available in different lengths, and with cable assemblies and replacement docking spool bodies. The LRN & N series torches also share common consumables with the complete D/F product line.

The D/F torch is famous for the fact, that if it is chilled properly, the welder can grab the chrome front water-cooled barrel (not the copper gas nozzle/cup) of the torch with their bare hand and it will be cold to the touch seconds after welding. With the proper chiller, this can be done even after a 4 hour arc time. If you are currently having problems using the Tregaskiss Tough Gun I.C.E™ (Integrated Cooling Enhancer) because of high amperages, long duty cycles resulting in torches overheating, expensive gas diffusers, and short consumable life, this series of D/F Automatic Water-Cooled Torches is a superior alternative. There are no exterior water lines that can be damaged running down the outside of the torch. The D/F LRN torches are completely water-cooled throughout. Make certain the cooling water supply is at least the minimum flow rate of 1 gallon per minute (for each inner body), at 40 psi (80 psi maximum) with a 6 gallon reservoir and a recommended 30,000 BTU/hr cooling capacity. Gun ratings are affected by shielding gas used, arc time, cooling time and inlet water temperature. D/F Machine Specialties does not manufacture or sell chillers, we only recommend them.

Each D/F Machine Specialties welding gun is fully assembled and ready to install. In order to make the installation complete, the code number, wire size, wire feeder make/model (Lincoln wire feeders, Miller wire feeders, Tweco 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.
