11101204 - Tweco 11-45 Contact Tip for 0.045" Wire (25 Pack)

Keep Your Arc Stable with Tweco 11-45 Tips

Every welder knows that the contact tip is the final transfer point for welding current, and a worn tip can ruin an otherwise perfect bead. This 25-pack of Tweco 11-45 contact tips ensures you have plenty of fresh consumables on hand for your 0.045" wire projects. Designed for the classic Tweco No. 1 MIG gun, these tips are the industry standard for light fabrication and repair work.

Why struggle with burnback or erratic arcs caused by keyholed tips? These 11-series tips are machined to tight tolerances, ensuring the wire slides through with just the right amount of contact. The copper alloy construction handles the heat of the arc while resisting spatter adhesion better than inferior generic alternatives. Whether you are welding mild steel frames or doing automotive bodywork, a fresh tip is the cheapest insurance for a high-quality weld.

The 11-45 is specifically sized for 0.045" (1.2mm) wire, a common size for structural work and heavier gauge sheet metal. The threaded base locks securely into your diffuser, preventing gas leaks or loose connections that could disrupt shielding coverage. With 25 tips in a single package, you can swap them out the moment you suspect wear, keeping your focus on the puddle rather than troubleshooting your gun.
