0390-0055 - Victor Mixer Assembly Kit for CA2460/CA2470

Detailed Technical Overview

The Victor 0390-0055 Mixer Repair Kit is a critical maintenance component designed specifically for the refurbishment of Victor's heavy-duty cutting attachments, notably the CA2460 and CA2470 series. In oxy-fuel cutting systems, the mixer is the precise internal component where the oxygen and fuel gas (such as acetylene or propane) meet to form the preheat flame. Over time, the internal passages of a mixer can become fouled with carbon deposits, or the seating surfaces can wear, leading to improper gas ratios, flow restrictions, or dangerous conditions like backfires and flashbacks.

This kit provides the necessary OEM components to restore the mixing chamber to its original factory specifications. Using genuine Victor parts is essential for maintaining the safety certifications of the equipment. The CA2460 and CA2470 attachments are widely used in industrial fabrication and demolition, often subjected to harsh environments. Replacing the mixer assembly is a standard procedure during a comprehensive torch rebuild. This kit ensures that the seating surfaces align correctly with the torch handle and the cutting tip, preventing gas leaks that could compromise operator safety.

Technicians should verify the model number of the cutting attachment before installation, as mixer designs vary significantly between torch series (e.g., the CA1350 vs. CA2460). The 0390-0055 is engineered to handle the flow rates associated with the 300-series torch handles that typically drive the CA2460/70 attachments. Proper installation of this kit restores the 'crisp' neutral flame required for high-quality cutting and extends the operational life of the tool.
