ESAB updates Tweco VELOCITY2 GMAW consumables

Tweco®, an ESAB brand, has introduced the VELOCITY2™ series of GMAW consumables for its Spray Master™, Classic Number, and Supra SEHD series GMAW torches. The heavy-duty nozzle uses a nozzle insert that is keyed into place and overmolded with a high-temperature silicone compound, essentially producing a single part from two pieces; a copper shell crimped over the insert creates the final nozzle.

The conductor tube is made from a single piece of copper with machined threads to hold the contact tip and nozzle in place. An O-ring prevents gas leakage in the event of a downstream obstruction, and a silicone sleeve over the copper tube helps minimize radiant heat and improves impact resistance.
