18GL53 - Weldcraft 18GL53 5/32" Gas Lens Collet Body for 18SC Torch (2-Pack)

Upgrade Your 18SC Torch with Better Gas Coverage

If you are running a heavy-duty water-cooled rig like the Weldcraft 18SC or W-400, you know that heat management and gas coverage are everything. The Weldcraft 18GL53 Gas Lens Collet Body is the part you need to keep your welds clean and your arc stable. Designed for 5/32" (4.0mm) tungsten, this isn't just a standard holder—it's a gas lens. That means it has the mesh screen built right in to smooth out your argon flow. Instead of the gas coming out in a turbulent mess, it comes out in a straight, smooth column. This gives you way better coverage over the puddle and helps prevent porosity, even if you have to stick your tungsten out a bit further to see what you're doing.

We know that when you are pushing 400 amps, your consumables take a beating. That's why these genuine Weldcraft parts are made tough. They handle the heat better than generic knock-offs and ensure you get good electrical contact with your tungsten every time. A bad collet body can lead to an unstable arc or poor gas coverage, which ruins welds and wastes time. Swapping in a fresh 18GL53 helps you maintain that buttery smooth TIG arc you're looking for.

This pack comes with two (2) collet bodies, so you aren't left high and dry in the middle of a job. It's always smart to keep spares in your toolbox. These are specifically for the "Super Cool" 18SC series, so make sure that's what you're running. They won't fit a standard WP-18 or WP-26. If you are doing heavy aluminum or stainless work and need that extra gas protection, switching to a gas lens setup like this is one of the best upgrades you can make for your torch.

Why Use a Gas Lens?

Using a gas lens like the 18GL53 allows you to lower your gas flow slightly while still getting better coverage than a standard collet body. It also lets you extend the tungsten up to an inch in some cases, which is a lifesaver when you are welding inside a corner or a deep groove. It's all about control and visibility, and this part delivers both.
