D/F Water-Cooled "BIG MIG" 1000 Amp Machine Torch
The “BIG MIG” 1000 Amp High Current Machine Barrel is recommended for robotic welding applications where production demands the maximum durability and quality for robotic gas metal arc welding. The model NCM15 as provided will accommodate 4” slip-in current tips fastened by a collet action nut. The model HTM15 will accommodate 7/16“ threaded current tips by utilizing a tip adapter nut. The water-cooled nozzle accepts threaded gas nozzles ranging from 3/4” through 1-1/4” inner diameter. This barrel is primarily for wire diameters from 1/16” through 7/32” (1.6mm through 5.6mm). The suggested current level with the model NCM15 would be approximately 450 amperes. Maximum current capacity applicable to the model HTM15 is 1000 amperes. Remote mounting is accomplished by an insulated mounting bracket and utilizing a casing/conduit connected by an adapter to the torch and a feeder adapter to the wire drive.
The “BIG MIG” has two Water Out & Power Cables, increasing the continuous duty cycle rating to 1000 amps. These ratings are, however, dictated by the contact tip. The “BIG MIG” NCM (slip-in) series of contact tips is rated up to 700 amps (continuous duty cycle). If your welding application requires amperages above 450, you must change to the heavy duty threaded CuCrZr series of contact tips rated up to 1000 amps (continuous duty cycle).
The barrel model HTM (threaded contact tip) has a current capacity range of 1000 amperes. Rating will be contingent on the combination of current tip and shielding gas to be used. The model HTM employs threaded CuCrZr (chromium zirconium copper) current tips and will accommodate .030”-1/16” hard wire, .035”-1/8” cored wire and 3/64”-3/32” aluminum wire.
