High-Performance Tweco 24CT-75-S MIG Nozzles

Upgrade your welding setup with the Tweco 24CT-75-S Nozzle, available in a value-oriented 2-pack (Stock Code 1240-1434). Designed for the professional welder who demands reliability and performance, these nozzles are a staple for anyone using Tweco No. 3 (300A) or No. 4 (400A) MIG guns. The "CT" in the model number stands for Coarse Thread, a feature that sets this nozzle apart by offering a secure fit that resists seizing. This is particularly beneficial in high-heat environments where thermal expansion and spatter buildup can make fine-thread or slip-on nozzles difficult to remove for cleaning or contact tip changes.

The 3/4-inch bore size is the workhorse for heavy-duty applications. A wider bore allows for a broader umbrella of shielding gas, which is essential when welding at higher amperages or when maintaining a longer stick-out is necessary to reach into joints. This improved gas coverage helps eliminate weld defects such as porosity and oxidation, ensuring your welds pass inspection every time. The copper alloy construction is rugged and durable, capable of withstanding the harsh environment of industrial welding, including exposure to radiant heat and molten spatter.

Welders Supply understands that downtime is costly. That's why we recommend the Tweco 24CT-75-S for its balance of durability and ease of maintenance. The coarse threads allow for quick twists to remove the nozzle, clean out spatter, and get back to the arc in seconds. These nozzles are compatible with standard Tweco front-end consumables, making them a seamless replacement for your existing setup. Whether you are in the shop or out in the field, having a pack of these reliable nozzles in your toolbox ensures you are always ready to tackle the toughest jobs.
