407732 - Tweco .045 / 3/64 Inch MIG Contact Tip - W Series

Reliable Performance for Every Bead

When you are under the hood, the last thing you want to worry about is your contact tip failing. The Tweco MIG Contact Tip for .045" and 3/64" wire is built to keep you welding longer with fewer interruptions. Known for their durability and precision, Tweco consumables are the go-to choice for welders who demand consistency. This specific tip is a workhorse, designed to handle the heat and keep the current flowing smoothly to your wire.

One of the standout features of this tip is its versatility. It is sized perfectly for running standard .045" mild steel wire, which is a staple in heavy structural and fabrication work. But it doesn't stop there—it is also compatible with 3/64" aluminum wire. This means if you are switching between steel jobs and aluminum spool gun work, you have a consumable that understands the sizing requirements for both, providing a snug fit that ensures good electrical contact without binding.

We all know that a worn-out tip leads to a wandering arc and frustrating spatter. This Tweco tip is made from high-quality copper that resists wearing out too quickly. The hole stays round longer, keeping your wire aimed exactly where you want it in the joint. It screws in tight and stays tight, handling the expansion and contraction of hot welding days without working loose. This ensures that the power from your machine actually makes it to the puddle.

Whether you are repairing heavy equipment, fabricating trailers, or working on an aluminum boat, having a fresh, high-quality contact tip is the cheapest insurance for a good weld. Don't let a cheap or worn tip ruin your bead profile. Stock up on these Tweco tips to ensure your MIG gun is always ready to perform at its best. It’s a small part that makes a massive difference in how your machine runs.
