14H-116 Heavy Duty Contact Tip for Tweco & Magnum Guns (25 Pack)

Precision Engineered 14H-116 Contact Tips for 400A Applications

Optimize your MIG welding setup with the 14H-116 Heavy Duty Contact Tip, specifically engineered for 1/16" (1.6mm) wire welding processes. This high-performance consumable is manufactured to strict tolerances to deliver superior arc starting and stability. Designed as a direct replacement for the Tweco® 1140-1206, this tip is built to handle the thermal stresses of continuous welding at amperages up to 400A.

Superior Material and Construction

Manufactured from high-grade copper alloy tubing, the 14H-116 offers exceptional electrical properties. The heavy-duty classification signifies a robust wall thickness that effectively dissipates heat, preventing the tip from overheating during long weld cycles. The interior surface is machined to a smooth finish with a consistent inside diameter, which significantly reduces friction on the wire. This attention to detail minimizes wire drag and erratic feeding, common issues that can lead to weld defects.

Broad Compatibility and Application

This contact tip is the standard for versatility in heavy fabrication environments. It seamlessly integrates with:

• Tweco® Series: Fits No. 2, No. 3, and No. 4 air-cooled MIG guns.
• Lincoln Electric® Magnum® Series: Compatible with Magnum 250, 300, and 400 guns.
• Generic Tweco-Style Guns: Fits most MIG guns utilizing standard 14-series consumables.

The threaded design allows for quick replacement and ensures a solid mechanical and electrical bond with the gas diffuser (typically part numbers 52, 52FN, or 54A). This secure interface is crucial for maintaining consistent voltage at the arc.

Technical Specifications

The 14H-116 is designed for 1/16" wire, a common size for heavy plate welding and structural applications. The ID tolerance is strictly controlled to +/- .003 inches, ensuring optimal electrical contact without binding. Whether running solid wire or flux-cored wires, this contact tip provides the reliability professional welders demand. With clear part marking for instant identification, you can ensure the correct setup every time, reducing setup errors and enhancing productivity.
