KP4399-3 - Lincoln Electric Robotic Torch Cable for Fanuc 100iC

Restore Peak Performance to Your Fanuc 100iC Welding Robot

For welding automation technicians and operators, the condition of the torch cable assembly is often the difference between a smooth shift and a day full of alarms and weld defects. The Lincoln Electric KP4399-3 WC Torch Cable Assembly is the direct replacement for the cable bundle running through your FANUC 100iC robot arm. Over time, the repetitive motion of the robot—specifically the rapid articulation of the J4, J5, and J6 axes—takes a toll on internal liners and power conductors. When your cable assembly begins to fail, you experience erratic arcs, burn-backs, and bird-nesting that can halt production.

This assembly is designed to handle the unique "whipping" and torsional forces found in hollow-arm robots. It features a rugged outer jacket that protects the internal power cable, gas hose, and control leads from the friction generated inside the robot casting. The design ensures that the wire liner remains as straight as possible during complex maneuvers, promoting smooth wire feeding even with softer wires like aluminum or at high wire feed speeds. Installing the KP4399-3 restores the electrical integrity of your welding circuit, ensuring that the voltage you set at the power source is exactly what is delivered to the contact tip.

Maintenance is easier with parts that fit perfectly. Because this is a genuine Lincoln Electric component, the connections for the feeder and the torch neck are precision-machined for a secure fit, eliminating gas leaks and hot spots caused by loose electrical connections. Don't let a worn-out cable compromise your weld quality. Swapping out an old, kinked, or frayed assembly with the KP4399-3 is a proactive step to maintain arc stability, reduce spatter, and keep your robotic cell running at maximum efficiency.
