105Z57 - Weldcraft 105Z57 TIG Power Adapter for 9 & 17 Series Torches

Connect Your TIG Torch to Any Machine

If you are trying to hook up an air-cooled TIG torch to a stick welder, engine drive, or an older shop machine, you know the challenge: your torch has a single cable that carries both gas and power, but your machine has a big lug stud and no gas solenoid. The Weldcraft 105Z57 Power Cable Adapter is the solution. Often called a "power block," this solid brass adapter allows you to bolt your torch's power cable directly to the output stud of your welder while providing a separate port to feed in your shielding gas.

Built for Series 9 and 17 Torches

This specific adapter is sized perfectly for the smaller, more maneuverable air-cooled torches. If you are running a WP-9, WP-17, or WP-24 (including Flex, Valve, and Pencil models), this is the part you need. It converts the 3/8"-24 thread on your power cable into a solid lug connection. The side port allows you to screw in your regulator hose directly, bypassing the machine's internal gas plumbing—or lack thereof. This is especially useful for field welders using Bobcat or Trailblazer engine drives who need to switch to TIG welding quickly.

Durable and Conductive

Cheap adapters can overheat or strip out, causing gas leaks and poor arc starts. The Weldcraft 105Z57 is made from heavy-duty brass that handles the heat of 150 amps continuously. Whether you are working on a Syncrowave in the shop or a generator on a job site, this adapter ensures your shielding gas gets to the puddle and your welding current gets to the tungsten without interruption. It is a must-have accessory for any welder's kit who relies on air-cooled TIG setups.
