11601104 - Tweco 16S-45 Heavy Duty Contact Tip, .045 in Wire, 25-Pack

Reliable Performance for the Professional Fabricator

When you are under the hood and the sparks are flying, the last thing you want to worry about is your contact tip fusing or wearing out prematurely. The Tweco 16S-45 Contact Tip is the go-to choice for welders running .045" wire in heavy-duty applications. Built to handle the heat, these tips are rated for up to 600 amps, making them perfect for spray transfer modes and long, continuous welds on thick structural steel. If you are running a Tweco Spray Master or a No. 6 gun, these are the genuine replacements that keep your equipment running like new.

The 16S-45 isn't just a piece of copper; it's a critical part of your wire feeding system. The heavy-duty wall thickness helps pull heat away from the wire, keeping the tip cooler and preventing the wire from burning back and sticking. We all know the frustration of a burn-back stopping production; using high-quality, genuine Tweco consumables significantly reduces that risk. The threaded M8 base screws in tight to your diffuser, ensuring you have a solid electrical connection every time. No rattling, no loose fits—just consistent arc starts and smooth feeding.

Sold in convenient packs of 25, these tips are designed for the shop that burns through wire by the drum. The clear markings on the side mean you'll never accidentally grab the wrong size when you're in a rush. Whether you are fabricating heavy machinery, repairing structural beams, or working on production lines, the Tweco 16S-45 delivers the consistency you need. Swap out your worn tips with genuine Tweco 16 Series parts and experience the difference in arc stability and tip life. Keep your gun cool and your welds hot with the industry standard in MIG consumables.
