Lincoln Electric cable connector set. This set is precision-machined from special-contour extended brass and features heat- and oil-resistant molded covers for durability. Cables easily twist into position. These connectors provide a very stable connection, not to mention a high current and low resistance connection. Pins are easy to insert into the housing. If you are using #4 thru #1 Welding Cable these are the connectors you need. Flared ends means easy cable access allowing for easier insertion of the cable into the lugs hole.
