11601539 - Tweco 16PS-116 Pulsemaster Contact Tip 1/16-Inch (25 Pack)

Precision Engineered for Pulsed MIG Performance

The Tweco 16PS-116 Contact Tip is a premium consumable designed to meet the demanding requirements of high-amperage and pulsed MIG welding applications. Part of the renowned Pulsemaster series, these contact tips are manufactured to strict tolerances to ensure consistent electrical contact and superior arc stability. In pulsed MIG welding, the rapid fluctuation of current creates significant thermal and electrical stress on the contact tip. The 16PS series addresses this with a robust copper alloy construction and optimized geometry that facilitates efficient heat dissipation and current transfer.

This specific model is sized for 1/16-inch (1.6mm) welding wire, a diameter commonly used in heavy fabrication, structural steel, and shipbuilding. The internal bore is precision-drilled and smoothed to minimize friction, ensuring that the wire feeds smoothly without drag or micro-arcing inside the tip. Micro-arcing is a common cause of premature tip failure and unstable arcs; by maintaining a consistent contact patch with the wire, the 16PS-116 reduces these issues, leading to cleaner welds and less downtime for tip changes.

Supplied in a package of 25, these contact tips are an essential stock item for industrial operations running Tweco Pulsemaster MIG guns. The 16 Series design ensures compatibility with standard Tweco gas diffusers and conductors, providing a secure, leak-free electrical connection. Whether you are welding aluminum, stainless steel, or mild steel using advanced pulse waveforms, the Tweco 16PS-116 delivers the reliability required for professional results.

Technical Superiority

Tweco's manufacturing process involves high-quality copper alloys that resist annealing at high temperatures. This hardness retention is critical when welding at the high duty cycles often associated with 1/16" wire. The tips are designed to resist "keyholing"—the ovalization of the tip bore—which extends the usable life of the consumable and maintains the center-point accuracy of the wire placement.
