11501230 - Tweco 15H-35 WeldSkill Contact Tip 0.035-Inch (Pack of 25)

Precision Tweco 15H-35 Heavy-Duty Contact Tips

Maximize the performance of your Tweco WeldSkill MIG gun with the Tweco 15H-35 Contact Tip (Stock No. 1150-1230). These premium contact tips are precision-machined to strict tolerances, ensuring optimal electrical transfer from the power source to the welding wire. Designed for use with 0.035-inch (0.9mm) wire, the 15H-35 features a heavy-duty wall thickness that provides superior heat dissipation and structural integrity compared to standard tips. This results in a more stable arc, reduced micro-arcing inside the tip, and a longer service life in demanding industrial environments.

The contact tip is a critical component in the MIG welding circuit. A worn or inferior tip can lead to wandering arcs, poor bead profile, and frustrating wire feed issues. Tweco's 15 Series tips are manufactured from a specific copper alloy formulation that balances hardness with electrical conductivity. The 1/4"-20 threaded base ensures a secure electrical and mechanical connection to the gas diffuser, preventing loosening during thermal cycling.

This 25-pack is ideal for professional welders who demand consistency. The 15H-35 is compatible with a wide range of Tweco WeldSkill guns, often found in 140A, 180A, and 220A setups, as well as select Victor and Thermal Arc systems utilizing Tweco-style front-end consumables. By maintaining a tight tolerance between the wire and the tip bore, these consumables help maintain the correct stick-out and focal point, essential for producing high-quality, X-ray quality welds.
