WDW103 - Smith WDW103 Low Pressure Gas Saver with Pilot Light

Industrial Efficiency with the Smith WDW103 GASAVER

The Smith WDW103 GASAVER™ is a specialized gas economizer designed to streamline production brazing and welding operations where low-pressure fuel gas is utilized. Engineered for facilities using fuel gas at pressures less than 4 PSIG—typically natural gas—this device serves as both a safety station and a cost-saving instrument. In high-volume production environments, the cumulative cost of gas wasted during torch idling, start-up, and shut-down can be substantial. The WDW103 addresses this by automatically extinguishing the torch flame the moment the operator hangs the torch on the lever arm, cutting off the supply of oxygen and fuel gas to the tip while maintaining a small, adjustable pilot flame.

When the operator is ready to resume work, lifting the torch from the arm instantly restores the gas flow at the pre-set mixture, and passing the tip over the pilot light reignites the flame. This mechanism eliminates the repetitive and time-consuming task of manually adjusting valves and using a striker for every cycle. The device is compatible with injector-type torches and is specifically calibrated for low-pressure applications. While it excels with natural gas, it can also control hydrogen fuel gas, provided that a stable fuel like propane or natural gas is used to supply the pilot light. The unit is UL Listed, ensuring it meets rigorous safety standards required by America's largest production plants.

Installation of the WDW103 into a gas manifold system transforms a standard brazing station into a high-efficiency cell. By removing the need for constant valve manipulation, operators can focus entirely on part manipulation and joint quality. The unit is robustly constructed in the USA and backed by a 1-year warranty, making it a reliable capital investment for reducing overhead in metal joining operations.
