The patented CK Flexible Purge Chamber is used in the Gas Tungsten Arc Welding (GTAW) /Tungsten Inert Gas (TIG) process to provide a completely inert atmosphere for the welding of reactive metals such as titanium, molybdenum, nickel-based and aluminium-based alloys, as well as non-reactive metals like stainless steel.

Unique to this design is the ability to draw a vacuum around the product to be welded by collapsing the chamber. The chamber is then filled through a perforated hose that encircles the bottom of the chamber. This filling process allows the argon gas to expel all atmospheric gases more effectively (through the top valve port) than traditional filling methods. This significantly reduces the time required to reach an inert atmosphere suitable for welding, while using considerably less gas than traditional rigid purge chambers.

TIG Accessories FAQs

Straight answers to the questions people ask most when choosing and using accessories for TIG welding.

What should I put in a water cooler?

Use the coolant recommended by the cooler's maker. Plain tap water can cause scale, algae and corrosion, and in cold weather can freeze and damage the pump and hoses. A proper coolant mixture protects against these problems.

Check the level before you weld, top up with the correct fluid, and never run the torch without coolant flowing. Change the coolant at the intervals the maker gives, and follow the maker's instructions on disposal.

What is a trailing shield and when do I need one?

A trailing shield is an attachment that fits behind the torch cup and sends a stream of shielding gas over the weld after the torch has passed. Some metals, such as titanium and stainless steel, stay hot enough to oxidise as they cool, so the extra gas protects them while they cool down.

It is most useful for reactive metals and for welds where discolouration is not acceptable. It must match your torch and be fitted so that it follows the weld evenly.

What is a flexible purge chamber used for?

It is a flexible enclosure that you fill with argon and weld inside, so the whole joint and the area round it sit in an inert atmosphere. It is used mainly for reactive metals like titanium, and for jobs where normal gas coverage cannot keep the hot metal clean as it cools.

You place the work in the chamber, purge it until the oxygen level is low enough, and then weld through the sleeves or openings. Follow the maker's instructions, and make sure that any enclosed space is properly ventilated, since argon displaces air.

What are purge flux, backing tape and foil tape for?

They are ways of protecting the back (root) side of a weld from air. Purge flux is a paste painted on the reverse of a stainless steel joint to protect it from oxidation when a gas purge is not practical. Backing tape is stuck to the back of the joint to protect the root. Foil or similar tape is also used to seal the ends and gaps of a joint when it is purged with gas.

Which is right depends on the metal and the job. Flux residue must be cleaned off afterwards, and some industries restrict what may be used, so check the requirements for your work and the maker's instructions.
