Ball-Point Lug for 4/0 Cable

This Tweco copper lug connects 4/0 AWG welding cable at a 45-degree angle. It handles up to 325 A at 80 V and fits a 17/32 inch stud hole. The insulated body protects the connection in automotive and industrial welding jobs.

For High-Current Cable Terminations

Suits technicians terminating heavy 4/0 gauge cable for 325 A service. Not for lighter gauge wires, lower amperage needs, or straight lug requirements. Buyers needing a different angle or stud size should look at other lug styles.

Simple Crimp or Solder Installation

The ball-point design accepts the cable end for crimping or soldering. Ensure the lug is rated for your cable gauge and current before fitting. The most common error is using undersized cable that cannot carry the 325 A load safely.

Questions about this item

What cable gauge does the 325 A ball-point lug accept?

The lug is rated for cable up to 4/0 AWG, so the welding lead you already own must be that size or smaller to fit the ball-point connection.

Will the 45-degree copper lug clear a 17/32 in stud on my existing ground clamp?

Yes, the stud hole is 17/32 in diameter and the 45-degree angle is designed to align with standard clamp hardware without interference.

How can I confirm the insulated lug is carrying the full 325 A after installation?

Verify the cable is fully seated in the ball-point seat, the insulation shows no melting, and the joint stays cool during a test weld at the rated 80 V maximum.
