CK Water Cooled Torches FAQs

Practical answers on running, caring for and choosing parts for water-cooled TIG torches and their cable sets.

Which coolant should I put in a water-cooled TIG torch?

Use the coolant the torch and cooler manufacturers specify, normally a purpose-made torch coolant. Plain tap water is not suitable because scale and algae can build up and block the small passages in the torch head.

Do not use car antifreeze, which can thicken and clog the lines. Distilled water is, at most, a short-term emergency measure. Do not top up a pre-mixed coolant with water, as that changes its mix and its protection against freezing. If you are unsure, follow the cooler manual.

How often should I check or change the coolant and look after the cooler?

Check the coolant level regularly, ideally each day the cooler is used. Keep the cooler clean and blow dust off the radiator fins with compressed air (with the power off), more often in dusty workshops.

There is no single change interval for every coolant. Some low-conductivity coolants need changing more often than others, so follow the schedule in the cooler and coolant instructions. Discoloured, cloudy or slimy coolant is a sign it needs attention.

What should I check before striking an arc with a water-cooled torch?

Switch on the cooler and machine and look over the hoses and fittings while the coolant is flowing under pressure. Check for drips at the torch head, handle and connectors, and make sure all fittings are tight and nothing is cracked, bulging or kinked.

Also confirm the hoses are connected the right way round, so coolant reaches the torch head first. If you find a leak or the torch is running hot, stop and fix it before welding. Do not weld with a torch that is leaking or overheating.

Why does my water-cooled torch overheat?

The usual cause is poor coolant flow: a low coolant level, a cooler that is not running properly, a kinked or blocked hose, or debris in the narrow passages of the torch. Welding above the torch's rated current for long periods, or on a heavy duty cycle, also overheats it. Loose or worn front-end parts can add to the problem.

Stop welding, check the cooler level and operation, look over the hoses for kinks and leaks, and compare your settings with the torch rating. If the fault persists, have the torch checked rather than carrying on.
