11601137 - Tweco 16S-45 Standard Contact Tip 0.045 Inch (Pack of 25)

Keep Your Bead Smooth and Your Gun Running

Every welder knows that the contact tip is the heart of the MIG gun. If your tip is worn out or clogged, it doesn't matter how good your machine is—your weld is going to suffer. The Tweco 16S-45 is the industry-standard replacement tip for welders running 0.045" wire in their Tweco #3 or #4 guns. These aren't just generic knock-offs; they are built to handle the heat and abuse of daily fabrication work, giving you a smooth wire feed and a crisp arc start every time you pull the trigger.

Burnback and keyholing are the enemies of productivity. These 16 Series tips are designed with a smooth internal bore that reduces friction, helping your wire glide through without snagging. This means less bird-nesting at the feeder and fewer interruptions while you're in the zone. Whether you are welding structural steel, heavy equipment, or general repairs, having a fresh tip ensures your electrical contact is solid, which translates to better bead profile and less spatter.

This convenient pack of 25 ensures you aren't left scrambling for a spare when you're halfway through a project. The 16S-45 fits perfectly into standard gas diffusers on Tweco Spray Master and Professional series guns. Swap them out regularly to keep your welds passing inspection and your downtime to a minimum. Reliable, durable, and ready for work—just like you.
