11401440 - Tweco 14RZT-35 Robotic Contact Tip 0.035 Zirconium (25 Pack)

Tweco 14RZT-35 Heavy-Duty Contact Tips (25-Pack)

Upgrade your MIG welding setup with the durability of the Tweco 14RZT-35 Contact Tip. Sold in a convenient pack of 25, these tips are the professional's choice for high-amperage and high-duty-cycle applications. While designated as "Robotic" due to their precision and material grade, they are an excellent upgrade for manual welders using standard Tweco 14 Series consumables who experience frequent tip burn-back or wear.

Built for Heat and Endurance

Standard copper tips wear out quickly when pushed to the limit. The 14RZT-35 utilizes a specialized Zirconium-infused copper alloy that withstands extreme heat far better than standard DHP copper. This hardness allows the tip to maintain its structural integrity even when reflecting heat from the weld puddle for extended periods. For the welder, this means fewer tip changes, less troubleshooting of wire feed issues caused by worn tips, and a smoother, more stable arc. The 0.035-inch bore is precision-drilled to ensure optimal electrical transfer to the wire, which is essential for consistent penetration and bead appearance.

Tapered Design for Better Access

The tapered profile of the 14RZT-35 serves two main functions. First, it allows for better gas flow around the tip within the nozzle, reducing turbulence and improving shielding gas coverage. Second, the slimmer profile helps when welding in tight corners or deep V-grooves, giving you better visibility and access to the root of the weld. Despite the tapered shape, the heavy-duty walls provide ample thermal mass to dissipate heat away from the wire contact point.

Standard Fit, Premium Performance

These tips fit standard gas diffusers found on Tweco Classic and Spray Master series guns (up to 400/500 amps). If you are running 0.035" wire and find yourself replacing tips too often, switching to the 14RZT-35 Zirconium line is a cost-effective solution. The 25-pack quantity is ideal for fabrication shops, manufacturing plants, and serious hobbyists who value uptime and quality. Trust genuine Tweco consumables to deliver the performance your welding equipment was designed to achieve.
