For industrial fabrication environments where consistency and uptime are critical, the Tweco 11-45 Contact Tip (Part No. 1110-1144) delivers the reliability professionals demand. Designed specifically for use with 0.045-inch (1.2mm) welding wire, these contact tips are a staple in the Tweco 11 Series consumable line. Manufactured from high-grade copper alloy, they provide excellent thermal conductivity and electrical transfer, ensuring a stable arc and reduced burn-back issues during prolonged welding sessions.
The 11-45 tip features standard 1/4"-28 UNF threads, making it compatible with a wide range of MIG guns, including the popular Tweco WeldSkill series, Mini-MIG, and various other guns that utilize Tweco-style front-end parts. Precision machining ensures the bore diameter is strictly controlled to minimize friction while maintaining optimal electrical contact with the wire. This balance is essential for preventing micro-arcing inside the tip, which can lead to premature failure and wire jamming.
Supplied in a package of 25, this SKU is tailored for workshops and production lines that require a steady supply of consumables to maintain workflow efficiency. Regular replacement of contact tips is a key maintenance practice to ensure weld quality; having a bulk pack on hand reduces administrative overhead and ensures welders always have fresh consumables available. Whether you are welding mild steel, stainless, or flux-cored applications, the Tweco 11-45 offers the durability and performance expected from a leader in arc welding technology.
