Category: K1622-4-HTP

The TIG torch adapter allows you to connect any 18 Series or 20 Series water-cooled TIG torch to your LINCOLN® Precision TIG, Square Wave TIG, Invertec TIG welder, or any other TIG welder with a 1/2" Dinse connector. The adapter also comes with 3' of hose with a 5/8"-18 LH thread and features a second barb fitting to connect your gas hose. Equivalent to LINCOLN® part number K1622-4. The patented design clamshell makes installation a breeze, and we feel the design is an improvement over LINCOLN®'s system because our case splits in two without any tools.



The TIG torch water-cooler adapter also allows you to connect a standard Weldcraft® WP-18 or WP-20 water-cooled torch to a LINCOLN® welder. If you need a complete 18 Series or 20 Series water-cooled torch with the adapter already installed and ready to use on your LINCOLN® welder, we carry the torches in our store at considerable savings over purchasing the adapter and the torch separately. Please give us a call at 800-872-9353 if you don't see what you are looking for.

Timothy ★★★★★

The threads on this adapter matched up perfectly with my Lincoln's 1/2" fitting, so no wrestling or leaks after tightening. Hooked up my 20 Series torch and the water flow was steady from the first arc.

Jason ★★★★★

I needed a solid connection for my 20 Series torch on the Lincoln, and this adapter fit perfectly without any wobble. The brass threading feels durable and matched up smoothly. It solved my leak issue instantly.

Natalie ★★★★★

The cooling flow is noticeably steadier with this adapter, and the 1/2" thread sealed up tight on my machine without any wrench-fighting. Hooked it to an 18 Series torch and it's been running cool for a solid week of practice.
