The Lincoln Electric K1701-1 Timer Kit is a specialized control module designed to expand the functionality of compatible Lincoln Electric MIG welding power sources and wire feeders. This internal accessory integrates directly into the machine's control circuitry to provide four critical process enhancements: 4-step trigger interlock, spot welding mode, adjustable run-in speed, and burnback time control. By installing this kit, users can upgrade standard equipment to perform more complex welding tasks with greater precision and repeatability.
The 4-Step Trigger Interlock functionality alters the standard trigger logic. Instead of requiring the operator to hold the gun trigger continuously (2-step), the 4-step mode allows the operator to press and release to start the arc, weld without holding the trigger, and press and release again to extinguish the arc. This feature is essential for reducing hand fatigue during long, continuous weld seams in fabrication environments.
Spot Mode introduces a timing circuit that controls the duration of the arc. When the trigger is pulled, the machine welds for a pre-set time and then cuts off, regardless of whether the trigger is still held. This ensures uniform spot weld sizes and consistent penetration, which is critical for sheet metal work and repetitive tacking applications.
The kit also addresses arc initiation and termination mechanics. Adjustable Run-In Speed allows the wire to feed at a slower rate before the arc is established, preventing harsh starts and wire stubbing. Once the arc ignites, the wire feed speed ramps up to the welding setpoint. Conversely, Burnback Time Control manages the delay between the wire feed stopping and the welding output turning off. This precise timing prevents the welding wire from freezing in the cooling weld puddle, ensuring the wire tip is ready for the next ignition.
The K1701-1 is engineered for straightforward installation, typically mounting inside the wire drive compartment or control panel of the host machine. It connects to existing wiring harnesses, making it a plug-and-play solution for authorized service technicians or experienced maintenance personnel. It is supplied as a single package containing the module and necessary mounting components.
