To provide maximum resistance to the abuses of day to day service, the D/F Twin "MIG" torch is of heavy duty construction with all metal parts well insulated from current carrying members. The compact in-line body allows the D/F Twin "MIG" Torch to be used in a variety of applications with ease of maneuverability and can access hard to reach areas of operation. To facilitate reparability, all service lines are externally 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. The D/F Twin "MIG" Torch like all D/F torches is easily reparable, thus reducing downtime and increasing productivity.

The Twin Wire 1200 amp high current machine torch is recommended for robotic welding applications where production demands the maximum durability and quality for robotic gas metal arc welding. The D/F Twin Wire 1200 amp high current machine torch is not a Tandem torch. It is a true twin wire torch (two wires used with one power source). The Twin Wire 1200 Amp as provided will accommodate two 1/8" CrZr - (Cr-Chromium Zr-Zirconium) threaded current tips. The water-cooled nozzle accepts threaded gas nozzles. This barrel is primarily for wire diameters from .045" thru 1/8" (1.143mm thru 3.175mm). The suggested current level with the threaded gas nozzles with the Twin 1200 Amp would be approximately 750 amperes (depending on application). Maximum current capacity applicable to all models is 1200 amperes.

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), 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.

MODEL EXPLANATION

HTM - Heavy-Duty, Threaded Current Tip, Machine Barrel

FEATURES:

• Water-Cooled Inner Body & Nozzle
• Small Frontal Area for Hard-to-Reach Locations
• Heavy-Duty Construction for Long-Lasting Durability

Twin wire welding is recognized by the American Welding Society (AWS) as parallel wire that uses two wires but only a single power source and typically a single or dual contact tips. It can increase deposition rates by 20 to 30 percent versus single wire welding without significantly increasing heat input. The increase comes from the greater current density achieved by pushing a similar current over smaller, cross-sectional areas of wire.

Twin wire welding offers excellent penetration as the current density is directed axially along each wire. Wires can be aligned in the direction of travel for high travel speeds or oriented perpendicularly to the direction of travel to achieve a wider bead profile.

When twin wire welding, you must use a heavy-duty water-cooled contact assembly. A good contact assembly comprises heavy-duty CrZr (Cr-Chromium Zr-Zirconium) contact tips or a single contact tip with slots for both wires.
