K202 - Lincoln Electric Burnback Timer Kit for LN-8/LN-9

Precise Weld Termination Control

The Lincoln Electric K202 Burnback Kit is a critical accessory designed to enhance the performance of LN-8 and LN-9 wire feeders. In high-production and automated welding environments, the termination of a weld is just as critical as the start. If the power source cuts off instantly while the wire is still feeding or the puddle is still molten, the electrode can freeze in the crater. This phenomenon, known as "burnback" or sticking, creates downtime as operators must cut the wire, clean the tip, and potentially grind the defect. The K202 solves this by providing an adjustable delay in the power source output shut-off, allowing the wire to burn free of the puddle before the arc extinguishes completely.

Integrated Cold Inch Functionality

Beyond burnback control, this kit upgrades your equipment with a "Cold Inch" switch. This feature allows operators to feed wire through the gun without energizing the welding arc or wasting shielding gas. This is particularly useful during spool changes or when feeding wire through long conduit runs, ensuring safety and preventing accidental arc strikes. The kit is engineered to integrate seamlessly with Lincoln Electric's industrial wire feeders, maintaining the rugged reliability expected from the brand.

Application and Compatibility

Specifically engineered for the LN-8 and LN-9 series, this kit is indispensable for applications utilizing high wire feed speeds where the momentum of the motor might continue to drive wire briefly after the trigger is released. It is also highly recommended for automated setups where precision timing is required to ensure consistent, defect-free weld terminations cycle after cycle.
