- Surge tank design provides a constant mixture proportion from off to full flow.
- The hydrogen and argon are dynamically mixed which creates a steady uniform mixture. This action prevents the possibility of stratification, which can exist in some cylinder mixtures.
- Electrical circuit shuts off the hydrogen into the gas mixer if the inlet argon pressure is insufficient to create a proper mixture.
- explosionproof electrical construction for Class I, Division 2, Group B, C, D Hazardous Area.
- 1% H2 , 99% Ar
- 2% H2 , 98% Ar
- 5% H2 , 95% Ar
- 35% H2 , 65% Ar
The Model 8520 gas mixer is designed to mix hydrogen and argon for welding applications. These include shielding gas for plasma arc welding (PAW) and gas tungsten arc welding (GTAW). A typical example is plasma arc welding of stainless steel tubing in a tube mill.
The gas mixer has a flow rate range of 0-500 SCFH and is ideal for multiple users since the surge tank design will maintain a constant mixture proportion from off to full flow.
The gas mixer can not be used to create furnace atmospheres; these mixtures must be created by gas mixers designed with required safety controls.
