0386-0850 - TurboTorch ST-33 Extreme Self-Lighting Tip Size 3

Technical Overview of the TurboTorch ST-33 Extreme STK Tip

The TurboTorch ST-33 (Part Number 0386-0850) represents the pinnacle of air-fuel combustion technology, specifically engineered for HVAC and plumbing professionals requiring efficiency and precision. This Size 3 tip is part of the renowned Extreme series, which integrates TurboTorch's proprietary Swirl Combustion technology. This design creates a vortex of flame that maximizes heat transfer to the workpiece, ensuring rapid temperature elevation for both soldering and brazing applications. By concentrating heat more effectively than conventional tips, the ST-33 allows for faster completion of joints while simultaneously optimizing fuel consumption.

Designed for versatility, the ST-33 is compatible with both Propane and MAPP gases, offering flexible performance ranges depending on the fuel source. When utilizing Propane, the tip handles soft solders from 1/4 inch to 3 inches and silver brazes from 1/4 inch to 1 inch. Switching to high-energy MAPP gas extends these capabilities, allowing for soft soldering up to 3-1/2 inches and silver brazing up to 1-3/4 inches. This adaptability makes it an essential component for technicians dealing with varying pipe diameters and material requirements in the field.

Maintenance and longevity are key aspects of the ST-33's engineering. The unit features an easy-to-clean orifice, addressing one of the most common failure points in field torch tips. The screw-in design allows for quick interchangeability with STK series handles, providing a secure, leak-proof connection. The self-lighting mechanism is integrated directly into the tip assembly, providing reliable ignition without the need for flints or external lighters, thereby streamlining the workflow and enhancing safety in tight working environments.
