K3417-90 - Lincoln Electric Tweco-Style Female Cable Receptacle 3/0-4/0

Heavy-Duty Cable Management for Professional Welders

Upgrade your welding leads with the Lincoln Electric K3417-90 Tweco Style Receptacle, a heavy-duty female connector built for the serious fabricator. When you are pushing high amps through 3/0 or 4/0 cable, you cannot afford weak links in your power delivery system. This receptacle is designed to handle the thermal and electrical stresses of industrial welding, ensuring that your arc remains stable and your equipment stays safe. The Tweco style is a standard in the industry for a reason: it offers a balance of quick connectivity and rugged durability that withstands the daily abuse of the shop floor.

The K3417-90 is specifically engineered for larger cable diameters (3/0 through 4/0 AWG), making it suitable for high-output power sources used in structural steel, heavy equipment repair, and pipeline work. The female receptacle design serves as the socket end of your connection, ready to accept a male Tweco-style plug. This makes it ideal for creating extension cords that allow you to move freely around large workpieces without moving the power source, or for replacing worn-out panel sockets on compatible machinery.

One of the key benefits of this connector is its ability to minimize resistance. High resistance in cable connections leads to heat buildup, which can melt insulation and damage the connector itself. The Lincoln Electric K3417-90 ensures maximum contact area and secure clamping on the cable strands, promoting efficient current flow. This means your machine's settings are accurately reflected at the torch or stinger, giving you better control over the weld puddle.

Durability is built into every aspect of this product. The insulating covers are resistant to heat, oil, and impact, protecting the conductive metal parts inside. Whether you are working in a fabrication shop, on a construction site, or in a maintenance bay, this connector stands up to the environment. Invest in the K3417-90 to ensure your welding cables are as reliable as the rest of your Lincoln Electric equipment.
