Tweco 95151101 Ball Point Lug

The Tweco 95151101 is a copper welding cable lug rated for 150 A maximum current and 80 V maximum voltage. It is designed for welders and technicians making secure cable terminations on compatible equipment. The 45-degree angled body helps routing in tight workspaces. Insulation is included for added protection during use.

17/32 in Stud Hole and Ball-Point Connection

The lug accepts cable up to 1/0 AWG and features a 17/32 in stud hole diameter for bolting to terminals. Its ball-point connection style allows a swivel action that reduces cable stress and fatigue. The copper construction provides high conductivity for efficient power transfer. These features combine to simplify installation and improve joint reliability.

Check Cable Gauge and Stud Compatibility

Before ordering, verify that your welding cable gauge does not exceed 1/0 AWG and that the terminal stud matches the 17/32 in hole diameter. Confirm the 45-degree angle suits your routing space and that the 150 A and 80 V ratings meet your application requirements. The lug is insulated and restricted from sale in certain states.

Questions about this item

How often should the 1/0 AWG copper lug be inspected or replaced after heavy welding cycles?

Inspect the 1/0 AWG copper lug for pitting or discoloration after each major job; replace it if the 17/32 in stud hole shows elongation or the ball-point contact surface is eroded.

What is the first limit reached when running the lug at its 150 A rating for extended periods?

The 80 V maximum voltage rating becomes the limiting factor before the 150 A current capacity is exceeded during sustained high-power welding.

How much heat does the insulated 45-degree copper lug generate during all-day welding at 150 A?

The insulated copper lug dissipates heat through its 1/0 AWG cable connection; the 45-degree angle keeps the joint cooler by improving airflow around the ball-point contact.
