A-1 INST ALLA TION A-1 800 AMP TANDEM MIG TORCH T orch and Cable assembly weights Torch body: 6.8 lbs (cables elevated 1 ft above torch body, 4ft from torch body) Shielding Gas Flow Rate W ater Coolin.
800 AMP TANDEM MIG TORCH GENERAL DESCRIPTION The Tandem MIG 800 Amp Welding Torch is designed to deliver two wire electrodes to a single weld pool. The wire electrodes are electrically isolated from one another providing independent parameter control of both electrodes.
800 AMP TANDEM MIG TORCH CONT ACT TIP AND DIFFUSER INST ALLA TION The welding torch is equipped with specially designed diffusers. The diffuser is of a low profile design to accommodate the Tandem torch design. The diffuser is required to provide a current path to the contact tip and must be secured tightly.
800 AMP TANDEM MIG TORCH CONT ACT TIP SIZE Contact tips are available in standard sizes to match the wire specifications of the welding torch (.035, .045, .
B-1 OPERA TION B-1 ELECTRODES AND EQUIPMENT The Tandem MIG 800 amp torch has been designed for use with 0.035" through 0.062" diameter Lincoln Electric solid and metal cored steel GMAW wire weld- ing electrodes.
B-2 OPERA TION B-2 NOZZLE REAMING ST A TIONS During robotic applications a reamer should be employed to keep the nozzle clean. Reaming the noz- zle between welds will reduce the down time associat- ed with manual torch cleaning. The M18426-1 ream- ing station is an option that is recommended for noz- zle cleaning.
C-1 MAINTENANCE C-1 CONT ACT TIP REPLACEMENT Each application will dictate the frequency of contact tip replacement. Higher amperage, higher duty cycle operations will require more frequent contact tip replacement. The condition of the contact tip greatly effects the welding performance of the Tandem MIG process.
C-2 MAINTENANCE C-2 CONT ACT TIP ALIGNMENT During gooseneck replacement or after a torch colli- sion it may be required to check the contact tip align- ment. If using a robot, it is recommended that a tool center pointer is placed in the robotic cell to define the location of the lead wire.
