403-20-116-25 - Tregaskiss 1/16" Heavy Duty Taper Lock Contact Tips (25-Pack)

High-Performance Tregaskiss TOUGH LOCK™ Contact Tips

The Tregaskiss 403-20-116 Heavy Duty Contact Tip is a critical component of the renowned TOUGH LOCK™ Consumable System, engineered specifically for high-demand industrial welding environments. Designed to accommodate 1/16-inch (1.6mm) welding wire, these contact tips are manufactured with precision tolerances to ensure consistent electrical contact and arc stability. The "Heavy Duty" designation indicates a robust construction with increased wall thickness and superior copper alloy composition, allowing the tip to withstand the intense thermal stresses associated with high-amperage welding, such as that found in heavy equipment fabrication and structural steel manufacturing.

At the core of this product's performance is the innovative Taper Lock design. Unlike traditional threaded contact tips that can loosen due to thermal expansion and contraction, the Taper Lock system utilizes a smooth, tapered base that seats firmly into the compatible 404-20 gas diffuser. This design serves two primary functions: it locks the tip securely in place to prevent loosening during operation, and it maximizes the surface area of contact between the tip and the diffuser. This increased surface area facilitates rapid heat transfer away from the tip and into the gun neck, keeping the consumable cooler and significantly extending its service life. For automated and robotic welding cells where downtime is costly, the reliability of the TOUGH LOCK system is indispensable.

These contact tips are genuine OEM parts, ensuring they meet the strict quality standards required for precision welding. Using genuine Tregaskiss consumables prevents the common issues associated with aftermarket copies, such as poor conductivity, irregular wear, and premature failure. The 403-20-116 is optimized for use with Tregaskiss TOUGH GUN™ MIG guns and other compatible systems utilizing the TOUGH LOCK platform. By maintaining a cooler operating temperature, these tips reduce the likelihood of burnbacks and micro-arcing, ensuring a smooth, spatter-free weld deposit.
