FAL-450 - FAL-450 Aluminum Ferrule for 3/0-4/0 Welding Cable

Professional Grade Cable Ferrules for 3/0 and 4/0 AWG

The FAL-450 Aluminum Ferrule is a critical component for professional welders building or repairing high-amperage welding cables. Designed to fit 3/0 and 4/0 AWG copper welding cable, this ferrule solves the common problem of strand splaying when terminating cables into mechanical lugs, splicers, or electrode holders. Without a ferrule, tightening a set screw directly onto fine copper strands can shear them off, reducing the effective gauge of your cable and creating a weak point in your circuit.

Manufactured to precise standards, the FAL-450 slides easily over the stripped cable end. When compressed or used inside a mechanical connector, it deforms slightly to grip the strands uniformly, creating a solid, void-free mass. This ensures that the clamping force of the connector is distributed evenly across the entire conductor, rather than cutting into individual wires. The result is a connection that runs cooler and handles high amperage with minimal voltage drop.

This ferrule is particularly useful when working with highly flexible welding cables which have thousands of fine strands. It is an indispensable item for any welder's toolkit when outfitting power sources or extending leads. Ensure your equipment delivers its full rated power to the arc by terminating your cables with the proper hardware.

Technical Advantages

• Material Compatibility: Aluminum composition prevents galvanic corrosion issues when used with standard aluminum or tin-plated connectors.
• Secure Fit: Sized specifically for the diameter of 3/0 to 4/0 AWG cables for a snug, professional fit.
• Versatile Application: Ideal for use with cable lugs, quick-connects, and ground clamps that utilize set-screw or crimp connections.
