GMAW consumables’ contact tips have shielding gas ports for cooling

Tweco®, an ESAB brand, has introduced the patent-pending Velocity™ GMAW consumables platform. The contact tips feature shielding gas ports that keep the tip 30 percent cooler than other consumables, which improves parts life by up to five times or more in some applications, the manufacturer says.

The company has integrated the consumables on its Spray Master® GMAW guns and offers retrofit kits for existing Spray Master guns and the Classic Number series.

The cool-running contact tips reduce the ability for spatter to stick. The threadless, drop-in-style contact tips can be exchanged without the use of tools. This style eliminates problems with burnbacks as well.

Traditionally threaded nozzles are available, as well as a slip-adjustable nozzle with an indexed collar that enables the welder to define the contact tip-to-nozzle relationship – protruding, flush, or recessed.
