11601135 - Tweco 16ST-35 Contact Tip 0.035" (25 Pack)

Technical Overview of the Tweco 16ST-35 Contact Tip

The Tweco 16ST-35 (Stock Number 1160-1135) is a standard-duty contact tip belonging to the widely utilized Tweco 16 Series family of MIG consumables. Engineered for precision and reliability, this contact tip is specifically machined to accommodate 0.035-inch (0.9 mm) welding wire. The 'ST' designation indicates its classification as a Standard tip, optimized for general-purpose welding applications where consistent electrical transfer and arc stability are paramount. The tip is manufactured from a high-grade copper alloy, selected for its excellent thermal conductivity and resistance to electrical erosion, ensuring a prolonged service life even under sustained welding loads.

Dimensionally, the 16ST-35 features a 3/8"-24 UNF thread, allowing it to seat securely into compatible gas diffusers, such as the Tweco 52 and 54 series. This threaded connection is critical for maintaining a low-resistance electrical path from the gun's conductor tube to the welding wire. The internal bore is precision-drilled and finished to tight tolerances to ensure smooth wire feeding while maintaining sufficient electrical contact. Excessive clearance can lead to micro-arcing inside the tip, while insufficient clearance causes friction and bird-nesting; the 16ST-35 strikes the optimal balance for 0.035" solid and flux-cored wires.

This product is supplied in a package of 25 units, making it an ideal procurement choice for industrial environments requiring regular consumable replacement. It is fully compatible with a broad range of MIG guns, including the Tweco Spray Master, Tweco Professional No. 3 and No. 4, and numerous other MIG torches that utilize the 16 Series consumable platform. By adhering to strict OEM specifications, Tweco ensures that each tip in the pack delivers uniform performance, reducing troubleshooting time related to contact tip variability.
