The Forney Industries 57710 is a cable connector designed for use with No. 1 and No. 4 welding cable. It provides a secure electrical connection between heavy-gauge cable ends, maintaining conductivity under the demanding current loads common in welding applications. Sold in a package of 8, this connector suits job sites and shop environments where multiple terminations are made in a single setup. Installation is handled by welders and electrical tradespeople working with arc welding equipment and associated power leads.
This connector is suited for both shop and field welding applications where No. 1 or No. 4 gauge cable is used to carry welding current between the power source, electrode holder, and work clamp. The 8-unit package format supports contractors and service shops stocking consumable hardware for ongoing maintenance and equipment repair. It is appropriate for use in industrial, fabrication, and maintenance welding environments.
Designed as an OEM-style replacement connector compatible with No. 1 and No. 4 welding cable. Cross-references Forney part 32485.
Installation is typically performed by a qualified welder or electrician. Disconnect and de-energize the welding power source completely before servicing any cable connections. Ensure the cable gauge matches the connector rating before crimping or securing. Follow the welding equipment manufacturer's guidelines and applicable electrical codes when assembling or replacing welding cable terminations.
