K4678-120IC - Lincoln Electric AutoDrive SA Robotic Aluminum Feeder Package for Fanuc 120iC

Advanced Robotic Aluminum Welding Solution

The Lincoln Electric AutoDrive® SA One-Pak® (K4678-120IC) is a comprehensive robotic welding solution engineered specifically for the Fanuc 120iC robot arm. Designed to address the unique metallurgical and mechanical challenges of aluminum welding, this package integrates seamlessly with Lincoln Electric's Power Wave® technology to deliver industry-leading performance in automated environments. The core of the system is its sophisticated servo-driven push-pull wire feeding mechanism, which provides the precise torque and speed control necessary to feed soft aluminum wire over long distances without deformation or shaving.

System Integration and Compatibility

This One-Pak is pre-configured to mount directly onto the Fanuc 120iC, minimizing engineering time and installation complexity. The included mounting brackets and cable bundles are routed to accommodate the robot's range of motion, ensuring longevity and reducing cable stress. The system communicates directly with the Power Wave power source via ArcLink®, allowing for high-speed data transmission and real-time process monitoring. This digital integration ensures that wire feed speed is perfectly synchronized with the welding waveform, resulting in superior arc stability.

Touch-Retract Start Technology

A standout feature of the AutoDrive SA is the Touch-Retract Start technology. Unlike traditional high-voltage starting methods that can cause burn-through or spatter on aluminum, this system mimics a "lift-start" motion. The wire gently touches the workpiece and then retracts to establish the arc at a low current before ramping up to welding parameters. This results in clean, consistent starts every time, significantly reducing cycle interruptions and rework associated with poor arc ignition.

Comprehensive Package Contents

The K4678-120IC One-Pak includes everything required to equip the robot for aluminum welding: the push feeder, the pull feeder (torch mounted), specific mounting hardware, insulators, control cables, and the torch assembly itself. It also utilizes Magnum® PRO Copper Plus™ contact tips, which feature a larger diameter and greater thermal mass to dissipate heat more effectively, extending consumable life in high-duty-cycle applications.
