WDW101 - Smith WDW101 Acetylene Oxygen Gas Saver with Pilot Light

Maximize Efficiency in Production Brazing

The Smith WDW101 Gas Saver is a critical component for industrial environments where oxy-acetylene torches are used frequently but intermittently. Designed to bridge the gap between continuous workflow and operational pauses, this device serves as both a safety station and a cost-saving mechanism. In high-volume production lines, the cumulative cost of idling torches—burning fuel gas and oxygen while the operator repositions parts—can be substantial. The WDW101 addresses this by providing a mechanical arm that, when depressed by the weight of the torch, automatically shuts off the gas supply valves.

Operational Mechanics

The unit is engineered with a dual-valve system housed in a robust brass body. When the operator hangs the torch on the extending arm, the leverage actuates the valves to a closed position, instantly extinguishing the main flame. A separate, adjustable pilot light remains lit, consuming a negligible amount of gas. When the operator lifts the torch to resume work, the valves reopen, releasing the pre-set flow of oxygen and acetylene. By simply passing the torch tip over the pilot flame, the torch re-ignites instantly to the previous flame setting. This eliminates the need for repeated valve adjustments, ensuring consistent flame chemistry and heat output for every cycle.

Industrial Durability and Safety

Manufactured by Miller Smith, the WDW101 is built to withstand the rigors of heavy industrial use. The solid brass construction resists corrosion and heat damage, while the heavy-duty base ensures stability on the workbench. Beyond economics, the device enhances safety by ensuring that high-temperature flames are not left burning unattended or when the torch is set down on a bench. It provides a designated, secure location for the torch, reducing the risk of accidental burns or fire hazards in the workspace.

Key Applications

This unit is specifically calibrated for Acetylene and Oxygen systems. It is widely utilized in automotive manufacturing, HVAC component fabrication, and general metal assembly where brazing or soldering is a repetitive process. Installation is straightforward, with standard 9/16"-18 connections allowing it to be plumbed directly into the gas lines between the regulators and the torch hoses.
