K4678-MA1440 - AutoDrive SA Servo Torch System for Motoman MA1440

Advanced Robotic Aluminum Welding Solution

The Lincoln Electric AutoDrive® SA One-Pak® (K4678-MA1440) represents a significant leap forward in automated fabrication technology, specifically engineered for the Motoman MA1440 robotic platform. This comprehensive package addresses the inherent challenges of feeding soft aluminum wire in high-duty robotic cells. At its core is a sophisticated servo-driven push-pull feeder system that synchronizes perfectly with Lincoln Electric Power Wave® power sources. This direct digital communication allows for instantaneous adjustments to wire feed speed and torque, ensuring stable arc performance even during complex robotic movements.

A critical innovation in the AutoDrive® SA is its touch-retract start technology. Traditional aluminum welding often suffers from burnback or explosive starts that generate spatter and degrade contact tips. The AutoDrive® SA mitigates this by precisely retracting the wire at the moment of ignition, creating a clean, low-energy arc initiation. This method not only improves weld quality but significantly extends the lifespan of consumables. The system is designed to utilize Magnum® PRO Copper Plus™ contact tips, which feature a larger mass and superior heat dissipation properties compared to standard tips.

The One-Pak® configuration simplifies integration for systems integrators and maintenance engineers. It includes all necessary components for a complete setup: the servo torch assembly, mounting brackets specific to the Motoman MA1440, feeder cabling, and the breakaway disk for collision protection. By leveraging Power Wave Waveform Control Technology®, the system optimizes the welding output for aluminum's specific thermal and electrical characteristics, delivering consistent penetration and bead profile. This unit is an essential upgrade for industrial facilities aiming to maximize the uptime and quality of their automated aluminum welding operations.
