Victor CA411-3 Series 400 Medium Duty Cutting Attachment

Technical Specifications and Compatibility: Victor CA411-3

The Victor CA411-3 (SKU: 0381-1939) is a premium medium-duty cutting attachment specifically engineered for the 400 Series torch handles, most notably the WH411C. This unit is designed to optimize efficiency in mixed-fuel environments. Utilizing a Universal Spiral Head Mixer, the CA411-3 effectively atomizes and mixes oxygen with any standard fuel gas (Acetylene, Propane, Propylene, Natural Gas) directly in the head. This eliminates the need for separate injector-style attachments for alternate fuels, streamlining equipment management. The attachment utilizes standard Victor 3 Series cutting tips, accommodating sizes 000 through 6, which provides a versatile cutting range up to 5 inches (127 mm) in mild steel.

Construction and Durability
The chassis of the CA411-3 is built for longevity and performance. It features three inline stainless steel tubes that provide structural rigidity while minimizing the visual profile of the torch. This inline configuration is superior to triangular designs for visibility in tight corners or when following complex patterns. The head is constructed from die-forged brass, offering superior grain structure and resistance to thermal cracking compared to cast heads. The lever is also stainless steel, designed with a specific pivot point to offer smooth oxygen control with minimal grip force.

Connection and Sealing
Connecting the CA411-3 to a WH411C handle is secure and tool-free. The attachment features a redesigned brass coupling nut with an enhanced grip pattern for hand-tightening. Inside, a double O-ring seal mechanism ensures a positive, gas-tight seal immediately upon seating, preventing gas loss and potential safety hazards associated with leaks. The 90-degree head angle is standard for most manual cutting operations, providing optimal ergonomics for flat and horizontal cutting positions. This unit is backed by Victor's industrial 5-year warranty, attesting to its build quality.
