K2370-2 - Lincoln MAXsa 22 Submerged Arc Wire Feed Head

Precision Wire Feeding for Hard Automation

The Lincoln Electric MAXsa 22 Feed Head (Model K2370-2) is a premier solution designed specifically for hard automation applications in the heavy fabrication industry. Engineered to deliver uncompromising performance, this feed head is optimized for driving large-diameter submerged arc wires with precision and consistency. At the core of the MAXsa 22 is Lincoln Electric’s renowned heavy-duty gearbox paired with a robust cast aluminum feed plate, ensuring structural integrity and long-term durability even in the most demanding industrial environments.

Powering the feed mechanism is a high-torque 40VDC permanent magnet motor. This powerful motor provides exceptional traction, capable of pushing solid wire up to 7/32 inch (5.6 mm) in diameter without slippage or hesitation. Operators can fine-tune the performance by adjusting the gear ratio, achieving impressive wire feed speeds of up to 500 inches per minute (12.7 m/min). This level of control is essential for automated setups where consistent deposition rates and smooth starts and stops are critical for weld quality.

The MAXsa 22 is designed with versatility in mind. It seamlessly supports a wide range of configurations, including single, tandem, Twinarc, and multi-arc setups, making it adaptable to various project requirements. The feed head itself is rotatable, allowing for flexible and accurate fixturing within custom integrator setups. This flexibility ensures that the unit can be positioned exactly where it is needed to optimize the welding arc and workflow.

Included with the K2370-2 package are essential components to get your automation system running efficiently: the feed head itself, an adjustable wire straightener to ensure accurate wire placement, a cross-seam adjuster for fine-tuning, an electric flux hopper for consistent flux delivery, and a mounting bracket specifically designed for the TC-3 carriage. Backed by a 5-year warranty, the MAXsa 22 is a reliable investment for industries ranging from pressure vessel manufacturing to power generation and process piping.
