CABLE ASSEMBLY

Three cable assemblies deliver the necessary power and cooling fluids to the torch.

a) G3494-X Series:

Two of the cable assemblies supply power, wire and water cooling to each side of the torch. The third bundle is made up of the nozzle water cooling hoses, the air blast line and the shielding gas line.

b)G3494-XA Series:

Two of the cable assemblies supply power, wire, shielding gas and water cooling to each side of the torch. The third bundle is made up of the nozzle water cooling hoses and the air blast line.

Torch liners must be ordered separately (see ACCES- SORIES section). Customers who choose to run with different size wires in the lead and trail must use the correct liner for each wire.

CONSUMABLES

Heavy duty contact tips (KP2020 and KP2021 series) are recommended for all welding applications (see ACCESSORIES section). Standard or tapered contact tips should only be considered in special applications operating at low power.

Use only Tandem MIG diffusers with the Tandem MIG torch (see ACCESSORIES section). The Tandem MIG diffusers feature a narrow profile that prevents internal short circuits.

All of the gas nozzles (see ACCESSORIES section) also feature internal water cooling to assure a long life of the torch and nozzle. Water cooling of the nozzle reduces spatter accumulation. Nozzles are available for welding in locations where space is restricted while other nozzles are suitable for high deposition welding. Inside each nozzle is a shield to prevent spatter from bridging from the diffusers to the nozzle wall. The shield is made from a high temperature, glass-epoxy composite, or ceramic high temperature glass.

MOUNTING BRACKETS

A bracket for mounting the torch to a robot is available (see ACCESSORIES section). The bracket features an insulating plate to electrically isolate the torch from other equipment. The insulating plate also serves as a breakaway piece in the event of a severe collision.
