ESAB’s Tweco VELOCITY2™ consumables designed for GMAW

ESAB Welding & Cutting Products has introduced the Tweco® VELOCITY2™ series of GMAW consumables for the Spray Master™ and Tweco Classic Number Series GMAW guns. The heavy-duty nozzle uses a nozzle insert that is keyed into place and over-molded 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 minimizes radiant heat and improves impact resistance.

The consumables feature threadless, drop-in contact tips and integrate the contact tip seating area directly into the conductor tube. With medium- and heavy-duty consumables, the shielding gas flows from the conductor tube through four ports machined into the base of the contact tip, keeping the tip cooler.
