Eliminates stocking and handling premixed gases.
Various welding jobs require different mixes for the best performance.  On-site mixing of gases with Smith's proportional gas mixers eliminates inventorying and handling of costly premixed gases.  Individual gases can be mixed for specific welding or other industrial requirements resulting in improved performance.  Controlling the mixture of gases will result in lower cost and better controlled welds.

Reduces Set-up Time
No need to change cylinders, regulators, flowmeters or hoses when changing from one range of mixed gas to another.  Just turn the dial for whatever mixture you need.  No critical adjustment of flowmeters or complex calculations needed to achieve proper mixture rates.

Accurate - No Gas Separation!
Premixed gases may separate ( stratify ) into the individual gases within the cylinder.  Smith's proportional gas mixer eliminates gas stratification to always give you an accurate mixture.

Easy Operation, Training & Supervision in Welding Applications
Whether you are using a single welder or a manifold system supplying many welders, operation is simple and easy to use.  Ideal for training all personnel reguarding shielding gas mixtures because they can see the effect of various gas mixtures on weld appearance, quality and penetration.  Supervisors can easily note at a glance if the operator is using specified gas mixture.

Three Series of Mixers Available:
2-Gas Mixers in Standard and
High Capacity Models and 3-Gas Standard Models
The standard 2-gas series provides flow up to 180 SCFH and is suitable for most applications.  The high capacity two-gas series provides flows up to 900 SCFH and is designed primarily for large manifold sysems with station flowmeters in the welding industry.  It is ideal for other industrial applications requiring high flow rates.  The standard three-gas series provides flows up to 180 SCFH, high capacity series up to 600 SCFH and are designed for applications that require three gas mixtures.
