The Tweco 16S-40 (Part Number: 1160-1136) is a standard-duty contact tip designed for the 16 Series consumable platform. Engineered specifically for use with 0.040-inch (1.0mm) welding wire, this component is critical for maintaining consistent electrical conductivity and arc stability in MIG welding applications. The tip is manufactured from a high-grade copper alloy, selected for its optimal balance of thermal conductivity and wear resistance. It features a precision-drilled bore with tight tolerances to ensure smooth wire feeding while maximizing the electrical contact area.
This contact tip utilizes a 3/8"-24 UNF thread, making it compatible with standard gas diffusers found in Tweco Professional Series (No. 3, No. 4, and No. 5) and Spray Master Series (350 and 450) MIG guns. The 16 Series design offers a robust profile suitable for medium to heavy-duty industrial fabrication, providing sufficient mass to dissipate heat effectively during prolonged welding cycles. The overall length of the tip is 1.5 inches (38.1mm) with an outside diameter of 0.375 inches (9.5mm).
Supplied in a package of 25, these contact tips are intended for high-volume industrial environments where minimizing downtime is essential. Regular replacement of contact tips is necessary to prevent "keyholing"—the ovalization of the tip bore—which can lead to erratic arc characteristics and poor weld quality. The Tweco 16S-40 ensures reliable performance for structural steel, heavy equipment manufacturing, and general fabrication tasks requiring 0.040" wire.
