14H-52 - 14H-52 Heavy Duty Contact Tip .052 Tweco Style (25 Pack)

Technical Specifications

The 14H-52 Contact Tip is a premium-quality generic replacement designed to meet or exceed the specifications of original Tweco® parts. This heavy-duty contact tip is specifically machined for .052" (1.3mm) welding wire and is compatible with a wide range of industry-standard MIG guns, including Tweco® No. 2, 3, and 4 series, as well as Lincoln® Magnum® 250, 300, and 400 assemblies.

Manufactured from a durable copper alloy, the 14H-52 features a heavy-wall design that distinguishes it from standard duty tips. This increased wall thickness provides superior thermal conductivity and structural integrity, making it suitable for high-amperage applications up to 400 Amps. The tip utilizes a standard 1/4"-28 UNF thread for easy installation into compatible gas diffusers (such as the 52 and 54A series).

Key dimensional tolerances are strictly maintained, with the inside diameter held to +/- .003". This precision ensures optimal wire-to-tip contact, which is critical for maintaining consistent voltage and arc stability. Each tip is clearly marked with the part number and wire diameter for quick identification in a busy shop environment. Sold in packs of 25, these tips offer an economical solution for high-volume fabrication shops requiring reliable consumables.
