Engineered for performance and longevity, the TOUGH LOCK™ Standard Duty Contact Tip is an essential component for any welding setup utilizing 0.045" wire. Designed to be compatible with TOUGH LOCK Standard Duty Retaining Heads and Nozzles, these tips feature a dual-lead thread design that allows for easy rotation to a new wear position, significantly extending their life. Crafted from high-quality, high-conductivity copper through a precise mandrel-drawn process, these contact tips ensure optimal tolerances for consistent welding results. Additionally, the innovative Dual Taper Technology enhances the locking mechanism between the contact tip and neck, promoting improved weld consistency while maximizing heat dissipation to keep your consumables operating cooler and longer.
