Connector Range
This Zoro Select welding cable connector accepts cable gauges from 1/0 AWG up to 3/0 AWG. It is a Tweco-style female connector designed for use with arc welders. The brass body is insulated and measures 5.8 in in length. It is rated for a maximum current of 400 A and a maximum operating temperature of 40 Degrees C.
Insulated Brass Construction
The insulated brass housing provides electrical isolation during welding operations. A single ball-point cable connection secures the conductor inside the connector. This design aims to maintain a reliable contact surface under high amperage load. The connector is supplied as a single component without additional accessories or software.
400 A Capacity Headroom
The 400 A rating offers headroom for heavy-duty arc welding tasks within the specified cable gauge range. Operation above 400 A or beyond the 40 Degrees C temperature limit exceeds the design parameters. It is not suited for applications requiring higher amperage capacity or different connector gender configurations.

Questions about this item
When will the brass connector need replacement under heavy use?
The brass body is rated for 400 A continuous duty; replace it if the contact surfaces show pitting or the cable crimp loosens after repeated thermal cycles.
What is the first limit reached during sustained high-current welding?
The 40 °C maximum operating temperature is reached before the 400 A current rating becomes a constraint.
How much heat does the insulated connector generate during all-day arc welding?
At full 400 A load the connector runs up to its 40 °C limit, so the insulation stays warm but within specification.
