The GTAW (Gas Tungsten Arc Weldin) welding process or TIG (Tungsten Inert Gas) welding, the plasma arc of inert gas is responsible for protecting the pool of fusion the addition material and the tungsten electrode from the oxygen present in the atmosphere. It is common to use argon, but mixtures of Argon and Helium and mixtures of Argon and Hydrogen demonstrate increased productivity and quality.

The addition of Helium (He) to the TIG weld increases fluidity in the pool of fusion and penetration. In the need for greater fluidity and penetration, replace Helium with Hydrogen (H2). Note that Hydrogen must NOT be used for TIG welding on stainless, duplex, martensitic and ferritic steels.

For precision, safety and productivity in welding processes, the quality of the gas/mixture used is extremely important. This result is only achieved with mixtures of exact gases that allow repeatability throughout the process. Our gas mixers promote the ideal mix according to the demand of each process, offering models with fixed or variable output options.

Gas mixer designed and manufactured for the welding process, which allows mixing between 02 gases, with flow rate and outlet pressure control. From 0 to 100% content adjustable gas mixing output.

Gas mixer designed and manufactured for the welding process, which allows mixing between 02 gases, and therefore, capable of generating two different and independent gas mixtures. Factory-set (non-adjustable) gas mixing outputs.

Gas mixer designed and manufactured for the welding process, which allows mixing between 02 gases, and therefore, capable of generating four different and independent gas mixtures. Factory-set (non-adjustable) gas mixing outputs.

Compact gas mixer designed and manufactured for the welding process, which allows mixing between 02 gases, with flow rate and outlet pressure control. From 0 to 100% content adjustable gas mixing output. Requires cylinder/first stage pressure regulators for both input gases.

Gas mixer designed and manufactured for the welding process, which allows mixing between 02 gases directly from the cylinders, with flow rate and outlet pressure control. From 0 to 100% content adjustable gas mixing output. Both input gases should be connected directly to the gas mixer. No need to use cylinder/first stage pressure regulator.

Compact gas mixer designed and manufactured for the welding process, which allows mixing between 02 gases, with outlet flow rate control. From 0 to 100% content adjustable gas mixing output. Requires cylinder/first stage pressure regulators for both input gases.

Compact gas mixer designed and manufactured for the welding process, which allows mixing between 03 gases, with outlet flow rate control. From 0 to 100% content adjustable gas mixing output. Requires cylinder/first stage pressure regulators for both input gases.
