WDW1507 - Smith Gas Saver Acetylene Pilot Tube Assembly

Technical Overview of the Miller Smith WDW1507

The Miller Smith WDW1507 is a specialized replacement pilot light assembly designed exclusively for Smith Gas Saver systems utilizing acetylene fuel gas. In oxy-fuel welding and brazing operations, the Gas Saver (often referred to as an economizer) plays a pivotal role in reducing operational costs and enhancing safety. It functions by extinguishing the main torch flame when the torch is hung on the lever arm, while a small pilot flame remains lit. This pilot light must maintain a stable, consistent flame to ensure immediate re-ignition of the torch when the operator resumes work. The WDW1507 is engineered to meet the specific combustion characteristics of acetylene, ensuring a clean burn that minimizes carbon soot accumulation, which can be a common issue with improper or generic pilot assemblies.

Constructed to Miller's rigorous OEM standards, this pilot light assembly ensures proper fitment and gas flow regulation within the Smith Gas Saver body. The precise orifice sizing and tube geometry are critical for maintaining a pilot flame that is resistant to being blown out by ambient air currents in a busy shop environment, yet small enough to consume negligible fuel. Regular maintenance of the pilot light is essential for the longevity of the Gas Saver unit; a damaged or clogged pilot tube can lead to ignition failures, forcing operators to bypass the gas saver or use manual strikers, thereby negating the efficiency benefits of the system.

Installation of the WDW1507 is straightforward, designed to replace worn or damaged existing pilot tubes directly. It is not compatible with alternate fuel gases such as propane or natural gas, which require different pilot assemblies due to their distinct density and combustion ratios. By utilizing this genuine Miller Smith component, facility managers and technicians ensure the continued reliability and safety compliance of their oxy-acetylene stations.
