0386-0378 - TurboTorch CA-250 Standard Cutting Attachment for 100 Series Handles

Technical Overview of the TurboTorch CA-250 Cutting Attachment

The TurboTorch 0386-0378, also known as the Model 151-01FP CA-250, is a precision-engineered cutting attachment designed to expand the capabilities of standard 100 series torch handles. Manufactured under the Victor Technologies umbrella, this component is built to meet the rigorous demands of industrial cutting, welding, and heating applications. The unit is specifically calibrated for use with oxy-acetylene gas, leveraging a sophisticated spiral mixer design that ensures an optimal fuel-to-oxygen ratio for clean, efficient combustion and superior cut quality.

Structurally, the CA-250 is defined by its robust construction materials. The head is crafted from die-forged brass, a material choice that provides exceptional resistance to thermal deformation and mechanical impact. This is critical for maintaining the integrity of the tip seating surface over prolonged use at high temperatures. Connecting the head to the coupling nut are stainless steel tubes, which offer a high strength-to-weight ratio and excellent resistance to corrosion and bending. This triangular tube arrangement enhances the overall rigidity of the attachment.

One of the standout technical features of this model is the coupling mechanism. It utilizes a brass coupling nut equipped with a double O-ring seal. This design allows for a "hand-tight" connection that creates a secure, gas-tight seal without the need for a tightening wrench, reducing wear on the threads and facilitating rapid changeovers between welding nozzles and the cutting attachment. The cutting oxygen lever is also constructed from stainless steel, ensuring smooth actuation and resistance to the fatigue often seen in lesser materials. With a cutting capacity of up to 6 inches (152 mm) when equipped with the appropriate Series 3 cutting tips, the CA-250 is a versatile tool for medium-to-heavy duty fabrication tasks.
