639687 - ESAB PSF M8 Contact Tip 1.5mm (0.060") for Aluminum

Keep Your PSF Gun Running Smoothly

If you are running 1.5mm (0.060") wire through your ESAB PSF gun, the 639687 Contact Tip is the part you need to keep your arc stable and your welds clean. We all know that the contact tip is the unsung hero of the MIG gun—it takes the most heat and abuse, transferring all that current right into the wire. This M8 tip is built tough to handle that load. Unlike smaller M6 tips that can overheat and fuse quickly when you crank up the amps, the M8 thread on this tip provides a solid, cool connection to the gas diffuser, meaning you spend less time changing tips and more time burning wire.

This tip is designed to fit the workhorses of the ESAB lineup: the PSF 250, 305, 405, and 505. It also fits the water-cooled 410w and 510w models. If you are welding heavy plate or structural aluminum, you know that 1.5mm wire requires a tip that won't snag or drag. This tip features a smooth bore that lets the wire glide through without wandering, giving you that crisp, frying-bacon sound we all look for. It is especially good for aluminum jobs where feeding can be a nightmare with the wrong consumables; the precise sizing helps prevent the wire from binding up when the gun heats up.

Don't let a worn-out tip ruin your bead. When a tip gets keyholed, your arc starts to wander, and you end up with spatter everywhere. keeping a fresh pack of these ESAB 639687 tips in your toolbox ensures you are always ready to tackle the next big job. They are easy to swap out and built to ESAB's high standards, so you know they will thread in smoothly and seat perfectly every time.

Whether you are in a production shop or out in the field, reliability is everything. These tips deliver consistent electrical contact, which means consistent heat and penetration. Upgrade your consumables management by sticking with genuine parts that match your gun's specs perfectly. It’s a small investment that pays off in better weld quality and less frustration at the bench.
