The Miller/Tregaskiss 403-20-364 is a heavy-duty MIG welding contact tip constructed from mandrel-drawn copper. As a core component of the TOUGH LOCK Consumable Series and the Common Consumables Platform™, it is engineered for high-volume welding environments. The tip utilizes a tapered base and dual-lead threads to optimize electrical conductivity and thermal management, specifically designed for 3/64" (1.2mm) wire diameters.
Features
Dual-lead threads allow for faster replacement and secure seating within the retaining head
Tapered base design increases surface area contact to improve heat dissipation
Mandrel-drawn construction ensures strict tip tolerances and consistent wire feeding
Reduced vibration during high-speed wire delivery
Lower operating temperatures when mated with TOUGH LOCK retaining heads
Increased consumable service life in high-heat applications
High-conductivity copper material minimizes electrical resistance
