11101101 - Tweco 11-30 Contact Tip 0.030" (Pack of 25)

Keep Your Arc Stable with Tweco 11-30 Contact Tips

Every welder knows that the contact tip is the unsung hero of the MIG process. It’s the final point of contact where the power meets the wire, and if it’s worn out, your entire weld suffers. These Tweco 11-30 contact tips are the industry standard for running 0.030" wire, perfect for everything from autobody work to light fabrication. If you are running a Tweco No. 1 gun or the common Lincoln Magnum 100L found on many shop welders, these are the tips you need to keep in your toolbox.

Why buy a pack of 25? Because contact tips are consumables in the truest sense. Spatter buildup, burnback, and the constant friction of the wire eventually wear out the tip's bore. When the hole gets too big (keyholing), you lose electrical contact, leading to a stuttering arc and frustrating welds. Having a 25-pack on hand means you never have to stop a project to run to the store. You can simply swap out the tip the moment you notice performance dropping, ensuring your beads remain smooth and consistent.

These tips feature the classic 11-series design with 1/4"-20 threads, making them easy to install and remove. They are built from high-quality copper to handle the heat and current of daily welding. Whether you are a professional fabricator or a serious hobbyist, using fresh, high-quality contact tips like the Tweco 11-30 is one of the cheapest ways to improve your welding results instantly.
