LC-40M-R - LC-40 Male Welding Cable Plug - Red

Reliable Power Connections for Industrial Welding

The Lenco LC-40 Male Cable Connector (Red) is a staple in the welding industry, known for providing secure and efficient power transmission for manual arc welding. Designed to accommodate welding cables ranging from 1/0 to 2/0 (50mm² to 70mm²), this connector is engineered to handle the rigors of daily industrial use. The LC-40 series utilizes a proven cam-action design that pulls the two halves of the connector together tightly, ensuring a low-resistance connection that won't loosen due to cable tugging or vibration.

Safety and durability are paramount in the design of the LC-40M-R. The connector body is machined from a special brass alloy that offers high electrical conductivity, minimizing heat generation at the joint. This metal core is encased in a rugged, vulcanized rubber insulator. The red color of this specific model serves as an important visual indicator, typically used to identify the positive lead or a specific machine setup, helping to prevent cross-connection errors in busy workshops. The insulator is resistant to oil, grease, extreme heat, and cold, ensuring longevity even in harsh environments.

Installation is straightforward and requires no specialized crimping equipment. The cable is secured using a large oval-point screw, which can be tightened firmly with a standard 1/4" (6.35mm) Allen wrench. This feature makes the LC-40 an excellent choice for field repairs, allowing welders to replace damaged connectors on-site quickly. Rated for 350 Amps, this connector is compatible with other Lenco LC-40 style parts as well as Tweco MPC-2 series connectors, offering versatility for mixed-fleet equipment.
