L08040 - Lenco CT-40FA 45-Degree Machine Terminal Connector for LC-40

Technical Overview of the Lenco CT-40FA Terminal Connector

The Lenco L08040, also known as the Model CT-40FA, is a specialized cable terminal connector designed to facilitate efficient power transmission from welding power sources to secondary cables. Engineered with a 45-degree angle, this female terminal connector attaches directly to the output studs of a welding machine. Its primary function is to convert a standard threaded stud connection into a quick-disconnect cam-lock system compatible with Lenco LC-40 male connectors (and compatible equivalents like Tweco 2-MPC).

Constructed from a special high-conductivity copper alloy, the CT-40FA ensures minimal electrical resistance and heat buildup, which is critical for maintaining arc stability during high-amperage welding operations. The connector is rated for use with cable sizes ranging from 1/0 to 2/0 AWG and typically handles amperages up to 350A. The 45-degree offset is particularly beneficial for cable management; it allows the welding lead to exit the machine at a natural angle, preventing the 'kinking' or stress fractures often seen with straight 180-degree connectors or direct lug bolting. The unit includes a durable insulating cover that protects the connection from accidental shorting and resists degradation from oil, grease, and ozone.

Installation is straightforward: the terminal bolts onto the machine stud, providing a permanent receptacle for daily operations. This setup is ideal for shops that require frequent cable changes or storage, as the leads can be detached in seconds with a simple twist, rather than unbolting a lug.
