621-0001 - Replacement 0.035 Spray Contact Tip for MK Cobra Torches

Reliable Performance for Aluminum Welding

If you are running an MK Cobra or Python gun, you know that consistent feeding is the name of the game, especially when welding aluminum. This Generic replacement for the MK 621-0001 contact tip is designed to keep your arc smooth and your production line moving without breaking the bank. It is sized perfectly for 0.035" wire and is specifically engineered for spray arc welding, which is the sweet spot for most structural aluminum jobs.

Why Choose This Replacement?
Welding consumables add up, and finding a reliable alternative to the expensive OEM tips can significantly lower your operating costs. This tip offers the same fit and function as the original MK part. It seats perfectly in the gas cup and aligns with the liner to ensure the wire feeds straight and true. The copper material handles the heat of high-amperage spray transfer, resisting deformation and maintaining the electrical contact needed for a hiss-free, spatter-free weld.

Optimized for Push-Pull Systems
Push-pull guns are complex tools, and the contact tip is the final transfer point for all that welding current. A worn or poorly made tip can cause erratic arcs and frustrating burn-backs. This tip is built with the specific requirements of the Cobra system in mind. Whether you are fabricating boat hulls, repairing trailers, or working on signage, this 0.035" spray tip gives you the control and consistency you need to lay down perfect dimes every time. Keep a pack in your toolbox so you are never caught downtime with a fused tip.
