OVERVIEW

Heavy-Duty Power Transmission for Industrial Welding

The LC-40HDF Female Cable Connector is a premium-grade component designed to facilitate secure and efficient power connections in professional welding environments. Engineered specifically for heavy-gauge cables ranging from 3/0 to 4/0 AWG, this connector is built to handle the rigorous demands of high-amperage welding applications, boasting a rating of up to 500 Amps. It serves as the female half of a cable extension or machine connection pair, mating perfectly with corresponding LC-40HD male connectors.

At the core of the LC-40HDF is a precision-machined body crafted from a special copper alloy. This material choice is critical for minimizing electrical resistance, thereby reducing heat buildup at the joint and ensuring that maximum voltage reaches the arc. The connector utilizes a proven cam-lock design, which allows for a tight, positive lock with a simple twist. This mechanism is essential for preventing accidental disconnections caused by cable drag or vibration on the shop floor.

Safety and durability are paramount in the design. The metal connector is housed within a rugged, high-dielectric rubber insulator. This cover is resistant to heat, oil, grease, and ozone, providing long-lasting protection in harsh industrial settings. The installation process is straightforward, utilizing a large oval point screw and a copper shim to secure the stripped cable end firmly without damaging the strands, ensuring a high-contact surface area for optimal performance.

FAQ

The LC-40HDF is designed to fit 3/0 (000) and 4/0 (0000) AWG welding cables.

Generally, Lenco-style (LC) and Tweco-style (MPC) connectors are not interchangeable due to different cam designs. You should match LC-40 connectors with other LC-40 series parts.

This connector is rated for up to 500 Amps, making it suitable for heavy-duty welding applications.

The cable is secured using a large oval point screw that presses down on a copper shim (included), which clamps the copper strands firmly against the connector body.

Yes, the LC-40HDF includes both the metal connector body and the insulating rubber cover.

This is the Female connector (LC-40HDF). It accepts the male pin from an LC-40HDM connector.

While it might physically fit, it is not recommended. For 1/0 or 2/0 cable, you should use the standard LC-40 (non-HD) or specific 1/0-2/0 sized connectors to ensure a proper tight fit and strain relief.

You will need a cable stripper to remove the cable insulation and a hex key (Allen wrench) to tighten the set screw.
