15H-52 - Tweco Style 15H-52 Heavy Duty Contact Tip .052" (25 Pack)

High-Performance Replacement Contact Tips for Heavy Industrial Welding

The 15H-52 Tweco Style Contact Tip is a premium generic replacement designed to meet the rigorous demands of heavy-duty MIG welding. Engineered for compatibility with Tweco No. 5 series MIG guns (including models 55, 55SW, and 55H), these tips are an essential consumable for fabrication shops utilizing .052" (1.3mm) welding wire. This package contains 25 contact tips, providing excellent value for high-volume operations.

Manufactured from high-grade copper alloy tubing, these tips are built to withstand the intense heat and electrical current of industrial welding environments. They are rated for applications up to 500 amperes, making them suitable for structural steel, heavy equipment repair, and other thick-plate welding tasks. The tips feature a standard threaded design that ensures a tight, conductive fit with the gas diffuser, minimizing electrical resistance and heat buildup at the connection point.

Quality control is paramount in the production of these consumables. Each tip is machined with a strict inside diameter tolerance of +/- .003 inches. This precision ensures that the wire feeds smoothly through the tip without snagging or wandering, which is critical for maintaining a stable arc and achieving high-quality welds. The tips are also clearly marked with the part number and wire diameter, simplifying inventory management and reducing the risk of installation errors on the shop floor.

By choosing these 15H-52 style tips, procurement managers can reduce consumable costs while maintaining the reliability required for continuous production. They serve as a direct functional replacement for the OEM part number 1150-1205.
