Tweco 1110-1312 Mig Welding .045 Velocity Light Duty Contact Tips

Tweco 11101312 MIG Welding Contact Tips – Velocity2 Light Duty, .045 in (1.2 mm)

The Tweco 11101312 Velocity2 .045 in. (1.2 mm) MIG Contact Tip is engineered to set a higher standard in MIG welding performance. Unlike conventional tips that wear quickly and create feeding inconsistencies, the Velocity2 design was developed to deliver smoother arc performance, reduced spatter, and longer consumable life. This makes it the go-to choice for welders who want professional-grade results without the downtime of constant tip changes.

At the heart of its design is a direct copper-to-copper conductor path with fewer electrical connections, meaning less resistance, cooler running temperatures, and improved conductivity. Combined with its centered liner seating, the .045 in. contact tip ensures smooth and reliable wire feeding, reducing bird-nesting and misfeeds that can disrupt workflow. These engineering improvements directly translate into higher productivity, more consistent welds, and reduced operating costs.
