K52035-1 - Lincoln Electric Auto-Start Arc Sensor Cable 10ft

Technical Overview of the Lincoln Electric K52035-1

The Lincoln Electric K52035-1 is a specialized Cable Assembly Sensor designed to integrate with Lincoln Electric welding fume extraction systems. This component serves as the primary input device for the automatic start/stop functionality found on compatible stationary and mobile filtration units. The assembly features a 10-foot (3.0 meter) insulated cable terminating in a specific control board connector, ensuring seamless communication with the extraction unit's logic circuit.

Functionally, the K52035-1 operates on the principle of magnetic induction. The sensor end is typically wrapped around or clamped to the welding ground cable or power cable. When welding current flows through the power cable, the sensor detects the generated magnetic field and sends a low-voltage signal to the fume extractor. This signal triggers the fan motor to engage immediately. Once the arc is extinguished and current flow ceases, the sensor signals the unit to enter a run-on cycle (timer delay) before shutting down, ensuring residual fumes are cleared.

This OEM replacement part is critical for maintaining the energy efficiency and automated convenience of systems like the Statiflex or Mobiflex series (verify specific model compatibility in manual). It eliminates the need for manual switching or continuous running of the fan, thereby extending filter life and reducing shop noise levels. The cable is constructed with industrial-grade jacketing to resist minor abrasion and heat exposure common in welding cells.
