14-35 - 14-35 Contact Tip for Tweco/Magnum MIG Guns (.035 Wire)

Precision Engineering for MIG Welding

The 14-35 Contact Tip is a critical component designed for standard duty MIG welding applications utilizing .035" (0.9mm) wire. Engineered to meet the rigorous demands of industrial fabrication, this contact tip belongs to the widely used 14 Series family of consumables. It features a standard length of 1.5 inches (38.1mm) and is machined from high-grade copper alloy tubing. This material choice is deliberate, providing the optimal balance between electrical conductivity and hardness required to withstand the thermal cycling inherent in arc welding.

Dimensional accuracy is paramount in contact tip manufacturing. The 14-35 tip is machined with a precise 0.044" bore, held to tight tolerances (+/- .003"). This specific clearance is calculated to allow smooth wire feeding of .035" electrodes while maintaining sufficient electrical contact for stable arc transfer. A bore that is too tight causes drag and bird-nesting, while a bore that is too loose results in micro-arcing inside the tip and unstable voltage. This tip strikes the perfect balance for consistent performance.

Compatibility and Design

This contact tip utilizes a threaded base design, ensuring a secure mechanical and electrical connection with the gas diffuser. It is designed for broad compatibility, fitting Tweco® No. 2, No. 3, and No. 4 MIG guns, as well as Lincoln® Magnum® 200, 300, and 400 amperage gun assemblies. It is also compatible with Radnor® Pro 250 and 400 series equipment. The tip is rated for welding currents up to 400 Amps, making it suitable for a wide range of structural and manufacturing tasks.
