OVERVIEW

Reliable Power Connections with Lincoln Electric

Ensure your welding setup delivers maximum performance with the Lincoln Electric K3416-90 Tweco Style Plug. Designed for professional welders who demand reliability, this male connector is engineered to fit large-diameter welding cables ranging from 3/0 to 4/0 AWG. Whether you are building new welding leads, repairing damaged cables, or creating extension cords for increased mobility around the shop, this plug provides the secure connection you need.

Universal Compatibility

The K3416-90 features the industry-standard Tweco-style design. This means it is fully compatible with the vast majority of female Tweco-style receptacles found on power sources, wire feeders, and existing cable extensions. This universality makes it an essential component for any fabrication shop or field service truck, ensuring you can always connect your leads regardless of the equipment brand, provided it uses the standard twist-lock or push-lock Tweco configuration.

Built for Heavy-Duty Use

Working with 3/0 and 4/0 cables implies high amperage and heavy-duty cycles. This connector is built to handle that load. The internal metal components are crafted from high-conductivity alloys that minimize electrical resistance. Lower resistance means less heat buildup at the joint and more consistent voltage at the arc, resulting in smoother welds and less strain on your machine. The rugged outer insulator is designed to withstand impact, abrasion, and the general wear and tear of a busy industrial environment, protecting both the connection and the operator.

Easy Installation

Time is money, and the Lincoln Electric K3416-90 is designed for quick and easy installation. The mechanical connection system allows you to securely fasten the cable to the plug using standard tools, without the need for specialized crimping equipment in the field. This makes it perfect for on-the-spot repairs to keep production moving. Upgrade your welding leads today with this premium connector from a trusted name in the industry.
