11501212 - Tweco 15H-116 Heavy Duty Contact Tip 1/16" (25 Pack)

Heavy Duty Performance for High-Amperage Welding

Maximize the performance of your heavy-duty MIG welding operations with the Tweco 15H-116 Contact Tip. Specifically engineered for industrial environments, these contact tips are designed to handle the rigors of high-amperage welding while maintaining precise wire alignment and superior electrical conductivity. The "15H" designation indicates a heavy-duty construction, featuring a thicker copper wall than standard series tips, which allows for better heat dissipation and increased durability during prolonged welding arcs.

This specific tip is sized for 1/16" (1.6mm) welding wire, a common diameter for structural steel fabrication, heavy equipment manufacturing, and shipbuilding. The bore is precision-drilled to ensure smooth wire feeding, reducing the risk of burn-backs and micro-arcing inside the tip that can lead to premature failure. By maintaining a consistent electrical contact point, the 15H-116 ensures a stable arc and high-quality weld deposition.

Compatible with industry-standard Tweco No. 5 and No. 6 MIG guns, as well as other MIG guns that utilize the 15H series consumable platform, these tips feature a robust 3/8"-24 UNF thread. This ensures a tight, secure connection to the gas diffuser, minimizing electrical resistance at the joint. Supplied in a convenient pack of 25, this SKU (1150-1212) is ideal for workshops and production lines that require a reliable stock of consumables to keep downtime to a minimum.

Whether you are running flux-cored wires or solid wires in demanding applications, choosing genuine Tweco consumables ensures that your equipment operates at peak efficiency. The high-grade copper alloy construction resists deformation under heat, maintaining the tip's geometry longer than inferior aftermarket alternatives.
