122-11-100 - Stoody JS-100 Powder Spray Torch Kit

Precision Hardfacing and Thermal Spray System

The Stoody JS-100 Jet-Spray Torch Kit (SKU: 122-11-100) represents a pinnacle in oxy-fuel thermal spray technology, specifically engineered for the maintenance, repair, and overhaul (MRO) sectors. This system is designed to apply a wide variety of alloy powders—including nickel-base, cobalt-base, and iron-base formulations—to metal substrates through a controlled oxy-acetylene flame. The core of the JS-100 system is its ability to create a metallurgical bond between the overlay material and the base metal with minimal dilution, a critical factor when surface properties such as hardness, corrosion resistance, or wear resistance must be maximized without compromising the structural integrity of the component.

Technically, the torch operates on an aspiration principle where the flow of oxygen and acetylene creates a vacuum that draws powder from the mounted hopper into the gas stream. The mixture is then ignited at the tip, melting the powder as it is propelled onto the workpiece. The JS-100 features a distinct lever-actuated powder feed mechanism, granting the operator granular control over the volume of material being deposited. This allows for the creation of extremely thin, uniform layers that are difficult to achieve with traditional stick or MIG hardfacing methods. The kit is particularly adept at surfacing cylindrical parts like shafts and sleeves, as well as complex geometries found in glass molds, ceramic dies, and agricultural implements.

The equipment is robustly constructed to withstand the thermal cycling inherent in heating and spraying operations. It integrates seamlessly with standard industrial oxygen and acetylene supply lines, requiring no external power source or compressed air, which enhances its portability within a shop environment. By utilizing the JS-100, facilities can reclaim expensive components that have suffered from abrasion, erosion, or metal-to-metal wear, significantly extending equipment lifecycle and reducing replacement costs. The system is also highly regarded for its efficacy in cast iron repair, providing a method to build up worn surfaces without the cracking issues often associated with arc welding on cast materials.
