40AF-18 - Uniweld 40AF-18 Harris Style 18-Inch Cutting Torch, 90 Degree Head

Uniweld 40AF-18 Harris Style Hand Cutting Torch Overview

The Uniweld 40AF-18 is a premium hand cutting torch designed to replicate the performance and durability of the industry-standard Harris style equipment. Engineered for heavy-duty industrial applications, this torch features the signature triangular tube design. This configuration utilizes stainless steel tubes brazed into the head and valve body, providing exceptional structural rigidity and resistance to bending or warping under thermal stress. The 40AF-18 is an 18-inch model, offering a standard reach that is suitable for bench work, structural fabrication, and general scrap cutting.

One of the defining technical characteristics of the 40AF series is its universal pressure mixer system. Unlike torches designed for a single gas type, the 40AF-18 is capable of operating efficiently with a variety of fuel gases, including Acetylene, Propane, Propylene, and Natural Gas. The operator simply needs to install the appropriate Harris-style 6290 tip for the chosen gas and application. This versatility reduces inventory requirements for shops that utilize multiple fuel sources. The torch head is machined from brass for heat resistance and durability, angled at 90 degrees to suit the majority of manual cutting positions.

Operational control is managed via a bottom rear cutting oxygen lever. This lever placement is preferred by many operators for its ergonomic benefits, allowing the hand to naturally grip the handle while engaging the oxygen stream with the fingers or palm. The torch is equipped with standard "B" size (9/16"-18) inlet connections, ensuring compatibility with standard industrial hose sets. The valve knobs are color-coded and knurled for easy adjustment, even when wearing heavy welding gloves. With a cutting capacity that can extend up to 12 inches (depending on the tip size selected), the Uniweld 40AF-18 is a robust tool for demolition, construction, and maintenance operations.
