K4678-MA2010 - Lincoln AutoDrive SA Servo Torch One-Pak for Motoman MA2010

Precision Robotic Aluminum Welding Solution

The Lincoln Electric AutoDrive® SA One-Pak® (K4678-MA2010) is a sophisticated servo torch system engineered specifically to address the unique challenges of robotic aluminum welding. Designed for seamless integration with the Motoman MA2010 industrial robot, this package represents the pinnacle of automated wire delivery and arc control. At the heart of the system is the high-performance servo technology that synchronizes wire feed speed directly with the robot's motion and the power source's output, utilizing Lincoln Electric's proprietary Power Wave® Waveform Control Technology®.

One of the most critical technical advantages of the AutoDrive SA is its Touch-Retract Start capability. Traditional high-current starting methods often result in explosive arc ignition, leading to spatter on the workpiece and rapid degradation of the contact tip. The AutoDrive SA utilizes a precision servo mechanism to touch the wire to the workpiece and then retract it to draw the arc at a low current. This method virtually eliminates spatter and ensures a clean, consistent start every cycle, which is vital for high-volume automotive and fabrication environments where finish quality is paramount.

The system employs a dual-feeder approach—a push feeder located at the wire source and a pull feeder integrated into the torch head. This push-pull configuration is essential for feeding soft aluminum wires (such as 4043 or 5356 series) over long distances without buckling, shaving, or birdnesting. The One-Pak configuration simplifies the integration process for systems engineers and maintenance teams by bundling all necessary components, including the specific mounting brackets for the Motoman MA2010, cabling, and the breakaway disk for collision protection. By ensuring direct digital communication between the feeder, the robot controller, and the Power Wave power source, the AutoDrive SA delivers a level of process stability and repeatability that standard welding packages cannot match.
