11501254 - Tweco 15HFC-45 Heavy Duty Contact Tip (0.045") - 25 Pack

Maximize Uptime with Tweco 15HFC-45 Heavy Duty Tips

Keep your welding operations running smoothly with the Tweco 15HFC-45 Heavy Duty Contact Tip. Designed for professional welders who demand reliability, these tips are built to handle the heat of high-amperage welding. If you are running 0.045-inch wire through a Tweco #5 or #6 MIG gun, these are the genuine replacement parts you need to ensure consistent performance. The heavy-duty design features thicker walls than standard tips, which helps them stay cooler and last longer, even during extended welds on thick plate.

Nothing kills productivity like constant contact tip failures. Burnbacks, micro-arcing, and erratic feeding can often be traced back to a worn or inferior quality tip. Tweco's precision manufacturing ensures that the wire feeds smoothly and makes solid electrical contact every time. This results in a stable arc, less spatter, and better-looking welds. The 15HFC-45 is particularly effective for flux-cored welding applications where heat buildup is a major factor in consumable life.

This convenient 25-pack is perfect for busy shops and field trucks. Buying in bulk ensures you always have a fresh tip on hand when you need it, reducing downtime and saving money in the long run. These tips feature the standard 15 Series thread (5/16"-18), making them a direct fit for a wide range of Tweco-style guns found in shipyards, fabrication shops, and manufacturing plants across the country.

Don't compromise on your consumables. Using genuine Tweco parts like the 15HFC-45 protects your equipment and helps maintain the quality of your work. Whether you are fabricating structural steel or repairing heavy machinery, these heavy-duty contact tips deliver the durability and performance professional welders trust.
