Welding Cable Connector Set

This four-piece set provides male and female Tweco connectors rated for 500 A. They suit arc welders using cable between 3/0 and 4/0 AWG. Each connector measures 11.6 in long and uses a double ball-point connection. The brass bodies are insulated for safety.

500 Ampere Current Rating

The maximum current of 500 A is the figure that determines if these connectors match your machine. They accept cable gauges from 3/0 AWG minimum up to 4/0 AWG maximum. Select this set only when your welder and cable fall within that amperage and gauge range.

Questions about this item

How much current can the 500 A connector actually carry when it is installed on a welding lead?

The connector is rated for 500 A maximum current, so it will carry the full rated load of a compatible arc welder circuit without overheating.

What does the Tweco connector type limit in real use?

The Tweco interface locks the male and female halves together with a double ball-point connection, ensuring a secure fit that only works with matching Tweco-style plugs.

What cable gauges and length are needed for these 11.6 in brass connectors to fit properly?

They accept cable from 3/0 AWG up to 4/0 AWG and each connector measures 11.6 in long, so the lead must be stripped to suit that gauge range and overall length.
