40A-21 - Uniweld 40A-21 Harris Style Acetylene Cutting Torch, 21-Inch, 90-Degree Head

Heavy-Duty Harris Style Cutting Performance

The Uniweld 40A-21 Cutting Torch is a premium manual cutting tool designed for professionals who demand reliability and precision in their oxy-acetylene operations. Modeled after the classic Harris-style design, this torch features the distinctive triangular tube construction that is renowned in the industry for its superior strength and rigidity. This structural integrity makes the 40A-21 an excellent choice for harsh industrial environments, scrap yards, and construction sites where equipment durability is paramount.

Specifically engineered for use with Acetylene gas, this model utilizes a tip-mix system (when used with compatible tips) or head-mixing technology that optimizes the fuel and oxygen mixture for a hot, efficient cutting flame. The torch is compatible with standard Harris-style 6290 series cutting tips, ensuring that replacement consumables are easy to find and widely available. This compatibility allows operators to switch between different tip sizes to handle plate thicknesses ranging from light gauge sheet metal up to heavy steel sections (depending on the tip size selected).

Ergonomics and Safety

Safety and comfort are critical during extended cutting tasks. The 40A-21 features a 21-inch overall length, which is the standard size for general fabrication, providing an optimal balance between reach and control while keeping the operator's hands away from the intense heat of the cut. The 90-degree head angle is the most versatile configuration, suitable for the vast majority of flat and positional cutting work.

Control of the cutting oxygen stream is managed via a bottom rear lever. This lever placement allows the operator to grip the handle firmly and engage the cutting jet with a natural squeezing motion of the fingers, reducing hand fatigue compared to top-lever designs. The torch is equipped with standard "B" size (9/16"-18) hose connections, making it compatible with most standard twin welding hoses. Whether you are performing demolition, structural steel fabrication, or general maintenance, the Uniweld 40A-21 delivers consistent, high-quality cuts.
