Tweco 1023-1285 Air-cooled Mig Gun 250A 12 Ft Lincoln

Product Description

The TWECO 1023-1285 is an air-cooled MIG gun rated at 250 amps with a 60% duty cycle, designed for GMAW, FCAW, and aluminum GMAW applications. Built around the VELOCITY2a Spray Master V250 platform, this gun ships with VELOCITY2 front-end consumables already assembled and connects to compatible power sources via a Lincoln-style connector. The 12-foot cable length gives welders comfortable working range in light to medium-duty fabrication environments. Gas-ported contact tips are a core design feature, reducing heat buildup and extending tip service life. The threadless tip design allows fast consumable changes without tools.

This MIG gun is suited for light to medium-duty fabrication shops running GMAW solid wire, flux-cored wire (FCAW), or aluminum GMAW processes. Wire diameter compatibility spans 0.035 to 0.045 inches, covering the most common wire sizes used in structural tack work, sheet metal, and general production welding. It pairs with power sources equipped with a Lincoln-style connector. The included standard conductor tube is part number 1240-1374, and the conduit liner is a 42 Series unit.
