Gas traction spring operates opposite of compression gas springs. It finds uses in tensioners on mechanical assemblies and belt drives.

The gas train contains a gas connector ball valve, main pressure regulator, dual gas safety shutoff valve, high & low gas pressure safety switch, it proof of closure switch and zero gas regulator. It regulates the amount and the pressure of gas to burners. They also keep gas out of the combustion chamber whenever equipment is cycled or shut off.

Gas tungsten arc welding, also known as Tungsten Inert Gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces energy, which is conducted across the arc through a column of highly ionized gas and metal vapors known as plasma. GTAW is most commonly used to weld thin sections of stainless steel and light metals such as aluminum, magnesium, and copper alloys. The process grants the operator greater control over the weld than competing procedures such as shielded metal arc welding and gas metal arc welding, allowing for stronger, higher quality welds. However, GTAW is comparatively more complex and difficult to master, and furthermore, it is significantly slower than most other welding techniques.
