Tweco 95151110 Copper Lug
The Tweco 95151110 is a copper ball-point lug rated for 325 A at up to 80 V. It accepts cable up to 4/0 AWG and features a 45-degree angle for routing in tight welding setups. The stud hole measures 17/32 in and the lug is uninsulated. Professional welders and maintenance teams use it for heavy-duty cable terminations.
Installation checks
Verify that your welding cable gauge does not exceed 4/0 AWG and that the circuit current stays within 325 A. Confirm the stud or terminal bolt matches the 17/32 in hole diameter before crimping. Ensure the 45-degree orientation suits the available clearance on your workpiece or machine. The lug is supplied uninsulated, so plan for appropriate sleeving or tape if insulation is required by your safety code.
Thermal and electrical behaviour
Copper construction provides low resistance at the rated 325 A, keeping temperature rise minimal during normal welding cycles. No forced cooling or fan is needed because the lug is a passive connector. Power draw is determined entirely by the welding machine and cable length, not by the lug itself. Noise is negligible as there are no moving parts or active components.

Questions about this item
What comes with the Tweco 95151110 lug and is any extra hardware needed?
The package contains the copper ball-point lug only. You will need to supply the 4/0 AWG welding cable and a 17/32 in stud bolt for mounting.
How do I decide between the 45-degree angle and other lug styles?
Choose the 45-degree version when the cable must run at an angle to the terminal; a straight lug is better for direct in-line connections.
What does the 325 A rating mean when the lug is installed on a machine?
It is the maximum continuous current the copper lug can carry at up to 80 V when crimped to 4/0 AWG cable and bolted to a 17/32 in stud.
