Tweco L-2040 Ball-Point Mechanical Cable Lug 2/0-4/0

Reliable Field Repairs Made Easy

When a welding cable fails in the middle of a job, you need a fix that is fast, strong, and reliable. The Tweco Ball-Point Lug is the welder's choice for quick cable termination without the hassle. Forget about hunting for a massive crimping tool or dragging out a torch to solder a connection. With this mechanical lug, all you need is a strip of cable and an Allen wrench. It is designed to get you back under the hood welding in minutes, not hours.

The secret is in the ball-point screw. Standard set screws can cut into your copper strands, causing them to break over time and weakening the connection. Tweco's ball-point design presses down firmly and evenly, gripping the cable tight without slicing the wires. This means you get full power transfer to your arc and a connection that won't overheat. Built tough for the shop floor, this lug handles 2/0 to 4/0 cable sizes easily, covering the most common heavy-duty leads.

Whether you are setting up a new ground clamp, replacing a worn-out whip end, or connecting to a power source, this lug fits standard 1/2-inch studs perfectly. It is solid copper alloy, so it stands up to the heat and abuse of daily welding. Plus, if you ever need to change cables, just back out the screw and reuse the lug. It is a must-have spare part for any serious welding rig or maintenance locker.
