OVERVIEW

Get the Most Out of Your W-400 Torch

Equip your water-cooled TIG setup with the Weldcraft AK18C Accessory Kit, the perfect companion for your W-400 or legacy WP-18SC torch. When you are pushing 400 amps, you need consumables that can take the heat. This kit takes the guesswork out of selecting parts by bundling everything you need to start welding immediately. From the back cap to the tungsten, every component is genuine Weldcraft, ensuring your torch runs as smoothly as the day you bought it.

The star of this kit is the inclusion of Ceriated tungsten electrodes. Identified by their grey tip, these electrodes are a favorite among professional welders for their easy arc starts and ability to hold a point longer than pure tungsten. They work exceptionally well on both steel and stainless steel, giving you the versatility to handle different projects with a single tungsten type. The kit covers the most common heavy-duty diameters—3/32 inch, 1/8 inch, and 5/32 inch—so you are prepared for everything from root passes to heavy fill passes.

In addition to the tungsten, you get a matched set of collets and collet bodies designed to maximize conductivity and gas flow. The included alumina nozzles (#6, #7, and #8) provide excellent shielding gas coverage, protecting your weld pool from contamination. A short back cap is also included, which is a great upgrade for improving torch access in confined areas. Don't let worn-out consumables hold you back; keep your arc stable and your welds clean with this all-in-one accessory kit.

FAQ

The AK18C is designed specifically for Weldcraft W-400 and WP-18SC series water-cooled TIG torches.

The kit includes 2% Ceriated tungsten electrodes, identified by a grey color code.

This kit is optimized for the 18SC (Super Cool) and W-400 series. While some parts may thread in, the collet and collet body systems for the SC series are often distinct to handle higher amperage. Always check your torch manual.

The kit contains one of each: 3/32", 1/8", and 5/32" diameter tungsten electrodes.

Yes, it includes one short back cap suitable for the W-400/WP-18SC torch.

Ceriated tungsten is excellent for welding carbon steel, stainless steel, nickel alloys, and titanium. It can be used on both AC and DC settings.

The kit typically includes standard alumina nozzles, not gas lens nozzles, unless specified otherwise. The AK18C lists standard alumina nozzles #6, #7, and #8.

Ceriated tungsten is non-radioactive, offers easier arc starting at low amperages, and provides good arc stability, making it a safer and versatile alternative to Thoriated tungsten.
