WH100 - Smith WH100 Medium Duty Torch Handle 7-Inch

Technical Overview of the Smith WH100 Torch Handle

The Smith WH100 Medium Duty Torch Handle is an industrial-grade component designed for precision and durability in oxy-fuel applications. Engineered by Smith Equipment, this handle utilizes a robust "tube-within-a-tube" construction method. This design philosophy significantly enhances the structural integrity of the handle while keeping the weight manageable for the operator. The main body features silver-brazed connections, a manufacturing choice that provides superior leak resistance and mechanical strength compared to standard soldered joints. This construction ensures the handle can withstand the thermal cycling and physical rigors of daily industrial use.

A critical feature of the WH100 is its valve assembly. The handle is equipped with stainless steel ball-type needle valves. Unlike traditional tapered needle valves that can score and leak over time, the ball-type design ensures positive, chatter-free seating. This mechanism allows for precise flame adjustment and reduces uneven valve wear, extending the service life of the component. The valves are housed within a forged brass butt, further reinforcing the unit's durability. The internal threads are recessed and protected, mitigating the risk of thread damage should the torch be dropped or mishandled in a rough shop environment.

In terms of capacity and compatibility, the WH100 is highly versatile. It is rated as a medium-duty handle capable of cutting steel up to 6 inches (153 mm) thick when paired with the appropriate cutting attachments (such as the MC500 series). For welding applications, it supports material thicknesses up to 7/8 inch (22 mm). The handle is designed to function safely with all standard fuel gases, including acetylene, propane, propylene, and natural gas, provided the correct tips and regulators are employed. The inlet connections are standard 9/16"-18 "B" size fittings (right hand for oxygen, left hand for fuel), ensuring compatibility with a wide range of industrial hoses.
