Binzel Style M8 Contact Tip .045 Aluminum (Pack of 25)

Smooth Aluminum Welding with the Right Tip

If you are welding aluminum, you know the struggle: the wire is soft, it kinks easily, and it expands faster than steel when it gets hot. Using a standard contact tip for aluminum is a recipe for frustration, often leading to burnbacks, sticking, and the dreaded bird-nesting at the feeder. This Binzel-style 0.045" (1.2mm) contact tip is the solution. It is specifically designed with a slightly larger internal bore to let aluminum wire slide through smoothly, even as it heats up and expands during long welds.

These tips are built for the heavy-duty Binzel MB36 and Push-Pull 36 torches, featuring the robust M8 thread that handles the heat and current required for structural aluminum work. Whether you are fabricating boat hulls, trailers, or automotive parts, consistent wire feeding is the key to a good bead. A tip that grabs or drags on the wire will cause your arc length to fluctuate, resulting in soot, porosity, or an erratic puddle. These tips eliminate that variable, letting your push-pull gun do its job effectively.

Supplied in a convenient pack of 25, these tips ensure you have plenty of spares on hand. Aluminum welding can be unforgiving, and when a burnback does happen, you don't want to be searching for a replacement. Swap it out quickly and get back to laying down dimes. The pure copper construction provides excellent conductivity, ensuring the current transfers to the wire efficiently for a crisp, clean start every time.
