OVERVIEW

Optimized Electrical Connectivity for Industrial Welding

The LC-40 Male Cable Connector is engineered to provide superior electrical transmission and mechanical durability in demanding industrial environments. Designed specifically for 1/0 through 2/0 AWG welding cables, this connector utilizes a precision-machined copper alloy body. This material choice ensures high conductivity and minimal voltage drop across the connection, which is critical for maintaining stable arc characteristics during high-amperage welding operations. The connector is rated for a capacity of approximately 350 Amps, making it suitable for a wide range of structural and fabrication welding applications.

The mechanical design features a robust cam-action locking mechanism. When mated with a corresponding female connector, the cam lock creates a high-pressure contact area that resists loosening due to cable manipulation or vibration. This positive locking action not only ensures electrical integrity but also enhances safety by preventing accidental disconnections under load. The connection to the cable itself is achieved via a large, oval-point set screw, which can be tightened securely using a standard 1/4-inch (6.35mm) Allen wrench. A copper shim is typically provided to protect the fine copper strands of the welding cable from damage during tightening, ensuring maximum contact surface area.

Externally, the connector is housed in a specially formulated rubber insulator. This black boot is designed to withstand the harsh realities of the welding environment, offering resistance to heat, sparks, oil, grease, and abrasion. The insulator fits snugly over the metal body, providing essential electrical insulation and preventing short circuits against grounded workpieces. The tapered design of the boot ends ensures a tight seal against the cable jacket, reducing the ingress of moisture and contaminants that could lead to corrosion over time. This unit is fully interchangeable with standard Lenco LC-40 and compatible Tweco-style connectors, allowing for seamless integration into existing equipment fleets.

FAQ

This LC-40 connector is designed to fit 1/0 AWG and 2/0 AWG welding cables.

This is the Male end connector, typically used on the cable side that plugs into the machine or an extension.

You only need a cable stripper (or knife) and a 1/4-inch (6.35mm) Allen wrench / hex key to tighten the set screw.

It is generally rated for up to 350 Amps, depending on the duty cycle and cable size used.

Yes, this is fully compatible with Lenco LC-40 series and other standard cam-lock style connectors of the same size.

Yes, it includes the black rubber insulator boot.

No, 4/0 cable is too large for this connector. You would need an LC-40HD or similar larger connector for 3/0 or 4/0 cable.

Black is often used to denote the negative or ground side of the circuit, or simply for general use. Red is typically used for positive, but they are mechanically identical.
