CK Worldwide CK18 Water-Cooled TIG Torch
Description
A 350 A water-cooled TIG torch for heavy sections
The CK Worldwide CK18 is a water-cooled TIG torch rated at 350 A, ACHF or DCSP, at 100% duty cycle. CK lists it as the same as its CK300. Coolant circulates through the head and returns through the power cable, which allows long arc-on times at currents a gas-cooled body cannot sustain, for example on thick aluminium, heavy stainless fabrication or automated cells.
The CK18 head is compact for its rating and uses CK’s Max-Flo cooling design and Fail-Safe hose connections, as described in the 3 Series manual. It takes 3 Series consumables, the same family as the CK17 and CK26.

Setting up the cooling circuit
The 3-piece assembly feeds water in through the water hose and returns it through the power cable, so the return must always be on the power lead. A torch run with the flow reversed, or without coolant, will overheat quickly. CK specifies about one litre per minute. For coolers and machines with quick-disconnect sockets, CK lists QDWAP (water) and QDGAP (argon) 9 mm male adapters. Before first use, tighten all fittings and purge the regulator and torch with inert gas at 20 cfh.
Selection notes
Choose the CK18 when the welding current regularly exceeds what a gas-cooled torch handles. For lower currents with a cooler, the 250 A CK20 water-cooled TIG torch is smaller and lighter. The pencil CK18P gives a short profile for tight access. Specify the machine-side connector so the correct power cable adapter is supplied.
Head angle and style should follow joint access. A rigid head gives the most predictable position for repetitive work, a flex head bends to reach around fixtures, and the pencil head is compact for tight corners. Super-Flex hose packages are lighter and stay supple in hot conditions, which reduces wrist fatigue when the torch is used all shift. Coolant hoses age over time, so inspect them for cracking and leaks at each consumable change, and replace hoses rather than taping damaged sections.
If the torch is moved between machines, label the water and argon hoses at both ends so the coolant return always stays on the power cable.
