OVERVIEW

Heavy-Duty LC-40 Male Connector for 1/0-2/0 Cable

Upgrade your welding leads with the Lenco LC-40 Male Cable Connector in Red. This high-performance cable plug is the industry standard for quick, reliable, and safe welding cable extensions and machine connections. Built to fit 1/0 and 2/0 gauge cables, the LC-40M-R is rated for up to 350 Amps, making it ideal for a wide range of stick, MIG, and TIG welding applications where reliable power delivery is non-negotiable.

The heart of this connector is its precision-machined brass body, which ensures maximum current transfer efficiency. The unique cam-lock mechanism provides a positive stop when connected to a matching female receptacle, preventing accidental decoupling while you work. The exterior is protected by a heavy-duty red rubber insulator that withstands cuts, abrasion, and spark impact. The red color coding is essential for organizing your leads, allowing for instant identification of polarity or circuit paths at a glance.

Key Features:

  • Universal Fit: Compatible with Lenco LC-40 and Tweco MPC-2 profiles.
  • Easy Assembly: The single oval-point screw connection allows you to install or swap the connector using just a 1/4" hex key—perfect for quick fixes in the shop or on the truck.
  • Secure Lock: Cam-action design ensures a tight fit that resists vibration.
  • Durable Insulation: Vulcanized rubber boot resists shop chemicals and temperature extremes.

Whether you are building new leads or repairing old ones, the LC-40M-R provides the professional-grade connection you need to keep your arc stable and your production moving.
