K4678-100IC - Lincoln AutoDrive SA Servo Torch Package for Fanuc 100iC

Advanced Robotic Aluminum Welding Solution

The Lincoln Electric AutoDrive® SA One-Pak® (K4678-100IC) represents the pinnacle of robotic aluminum welding technology, specifically engineered to integrate seamlessly with the Fanuc 100iC robot arm. In the demanding field of automated fabrication, aluminum presents unique challenges due to its softness and thermal conductivity, often leading to feeding issues and inconsistent arc starts. The AutoDrive® SA system addresses these engineering hurdles head-on with a sophisticated servo-driven push-pull wire feeding mechanism that ensures precise wire delivery from the drum to the weld pool.

At the core of this system is Lincoln's innovative Touch-Retract Start Technology. Unlike traditional high-voltage starting methods that can cause explosive spatter and burnback, the AutoDrive® SA physically touches the wire to the workpiece and then retracts it to draw the arc. This method, synchronized perfectly with the Power Wave® power source, results in a clean, spatter-free ignition every single time. This level of control is critical for industries such as automotive and aerospace where weld integrity and cosmetic appearance are paramount.

This One-Pak® is a comprehensive turnkey solution designed to minimize integration time. It includes the specialized mounting brackets and insulators required for the Fanuc 100iC, along with the push feeder, pull feeder (servo torch), and all necessary cabling. The system utilizes Magnum® PRO Copper Plus™ contact tips, which feature a larger mass and superior heat dissipation properties. These tips are rated for over 250,000 starts and stops, significantly reducing downtime associated with consumable changeovers. By combining mechanical precision with advanced waveform control, the AutoDrive® SA delivers a robotic welding process that is both highly efficient and remarkably reliable.
