16S-116 - Tweco 16S-116 Heavy-Duty Contact Tip, 1/16", 25-Pack

Maximize Arc Stability with Tweco 16S-116

Achieve superior weld results with the Tweco 16S-116 Contact Tip, a heavy-duty component engineered for 1/16-inch (1.6mm) wire applications. In the world of Gas Metal Arc Welding (GMAW) and Flux-Cored Arc Welding (FCAW), the contact tip serves as the final transfer point for welding current. The 16S-116 is built to excel in this critical role, supporting amperages up to 600 amps. Its robust design makes it the ideal choice for structural steel fabrication, heavy equipment manufacturing, and other industrial sectors where high-deposition welding is the norm.

Superior Electrical Properties

The performance of a contact tip is largely dictated by its material composition and geometric precision. The Tweco 16S-116 is machined from high-quality copper alloy tubing. This material is selected specifically for its excellent electrical properties, allowing for efficient energy transfer with minimal resistance heating. By keeping the tip cooler, the alloy helps prevent "burn-back"—where the wire fuses to the tip—and extends the consumable's lifespan. The threaded connection further enhances this efficiency by ensuring a solid mechanical and electrical bond with the gas diffuser.

Engineering Tolerance and Compatibility

Tweco's commitment to quality is evident in the dimensional accuracy of the 16S-116. With an inside diameter tolerance held to +/- .003 inches, the tip provides a precise channel for the wire. This close tolerance ensures continuous electrical contact between the wire and the tip wall, which is essential for a stable, focused arc. If the bore is too loose, micro-arcing can occur inside the tip; if too tight, the wire may jam. Tweco's precision machining eliminates these variables. These tips are the standard OEM replacement for Tweco Spray Master guns and the classic No. 6 MIG gun, ensuring 100% compatibility and performance.

Maintenance and Identification

Regular replacement of contact tips is a best practice for maintaining code-quality welds. As tips wear, the exit hole becomes oval, causing the arc to wander. The 16S-116 comes in a pack of 25, providing a cost-effective solution for routine maintenance. The clear part number markings on the side of each tip make inventory management and part identification simple for operators on the floor.
