11101317 - Tweco Velocity VTSA-1/16 Aluminum Contact Tip (Pack of 10)

Industrial Grade Aluminum Welding Consumables

The Tweco Velocity VTSA-1/16 Contact Tip (SKU: 1110-1317) represents a significant advancement in MIG welding consumable technology, specifically tailored for industrial aluminum welding applications. Designed to accommodate 1/16-inch (1.6mm) wire, the VTSA series features internal geometries optimized to handle the higher thermal expansion rates of aluminum filler metals compared to steel. This precise engineering minimizes friction and prevents the wire from seizing inside the bore, a common cause of downtime in high-amperage aluminum fabrication.

Part of the revolutionary Velocity consumable platform, these tips utilize a threadless, drop-in design. Unlike traditional threaded tips that rely on threads for both retention and electrical transfer, the Velocity system uses a large surface area seating cone. This design maximizes electrical conductivity and thermal transfer, keeping the tip cooler during extended weld cycles. The absence of threads eliminates the risk of cross-threading and seizing, allowing operators to rotate or replace tips quickly without the need for pliers or wrenches.

Supplied in a package of 10, these contact tips are essential for maintaining uptime in automated and manual welding cells. They are compatible with Tweco Fusion MIG guns and Spray Master guns that have been upgraded with Velocity conductor tubes. By integrating gas ports directly into the tip seating area, the Velocity system also ensures smoother shielding gas flow, reducing turbulence and porosity in the weld pool—critical factors when welding sensitive materials like aluminum.
