K4400-50 - Lincoln FlexCut CNC Interface Cable 50ft

Maximize Your FlexCut Automation Potential

Upgrade your mechanized cutting capabilities with the Lincoln Electric K4400-50 CNC Interface Cable. Engineered for precision and reliability, this 50-foot interface cable is the definitive solution for connecting Lincoln Electric FlexCut plasma power sources to automated CNC tables and controllers. Whether you are operating a FlexCut 80 or FlexCut 125, this cable ensures that your power source and motion control system communicate in perfect synchronization, unlocking the full potential of your automated cutting line.

Critical Signal Transmission

Automation relies on accurate, real-time communication. The K4400-50 is wired to transmit essential operational signals that control the cutting process. These include:

• Start/Stop Signal: Initiates and terminates the arc precisely according to the cutting program.
• Arc Established (Arc OK): Confirms that the pilot arc has transferred to the workpiece, allowing the CNC table to begin motion.
• Voltage Divider Ratio: Provides scaled voltage feedback to the Torch Height Controller (THC), allowing the system to maintain the optimal tip-to-work distance automatically, even on warped plates.

Engineered for the Shop Floor

Standard cables often fail under the rigorous demands of a metal fabrication shop. The K4400-50 is built to withstand the tough conditions typical of plasma cutting cells. Its heavy-duty outer sheathing resists damage from dragging, crushing, and sparks. More importantly, the internal construction prioritizes signal isolation. High-frequency noise generated during the plasma process can disrupt sensitive CNC electronics; this cable is heavily shielded to ensure that control signals remain clean and interference-free, resulting in smoother cuts and fewer system faults.

Seamless Installation

Designed as a genuine Lincoln Electric accessory, the K4400-50 guarantees compatibility and ease of installation. The machine-side connector is keyed to fit the CNC interface port on FlexCut units perfectly, eliminating wiring guesswork. The 50-foot length accommodates large cutting tables and complex cable carrier (drag chain) routing, giving you the freedom to organize your workspace for maximum safety and efficiency. Invest in the K4400-50 to ensure your automated plasma system operates at peak performance with the reliability you expect from Lincoln Electric.
