Welding

Gas control is critical for welding processes when a shielding gas is required.

The shielding gas used in a TIG (tungsten inert gas) process can be argon, helium or a mixture. Argon is usually a better choice as it is heavier than air and tends to provide a better blanket over the weld.

Metal inert gas or MIG welding will typically use Argon, Carbon Dioxide or Helium as a shielding gas.

Mass flow controllers are typically used to automate the delivery of the shielding gas and come programmed with standard gas blends for welding applications. Manual gas control can be provided with a variable area flow meter with manual control valve. Products listed below are suitable for the welding industry.
