K4361-1 - Lincoln Electric K4361-1 TIG Foot Pedal (8-Pin)

Precise TIG Control for Multi-Process Machines

The Lincoln Electric K4361-1 Foot Pedal is an essential accessory for fabricators utilizing the POWER MIG 140 MP or LE31MP multi-process welders for TIG applications. TIG welding is a discipline that demands precision, particularly when working with thin materials or critical joints where heat input management is paramount. This foot pedal provides the operator with dynamic, real-time control over welding amperage, allowing for adjustments on the fly that a fixed setting on the machine face cannot offer. By depressing the pedal, the operator initiates the arc and can ramp up the current to the maximum setting dialed into the power source. Conversely, easing off the pedal reduces the heat, preventing burn-through and allowing for a controlled crater fill at the end of the weld.

Engineered with a 6-foot (1.8 meter) cable, the K4361-1 offers sufficient reach for bench work and standard workshop setups. The unit terminates in a specific 8-pin connector designed to mate perfectly with the receptacle on compatible Lincoln Electric machines, ensuring a secure and reliable signal transmission. This plug-and-play functionality eliminates the guesswork often associated with universal pedals or complex adapter configurations. The pedal's mechanics are tuned to provide smooth resistance, giving the welder tactile feedback that translates to finer puddle control.

Beyond simple amperage regulation, the K4361-1 plays a crucial role in the entire weld cycle. Fully raising the pedal not only extinguishes the arc but also signals the machine to begin the after-flow cycle, shielding the cooling tungsten and weld pool from atmospheric contamination. This integration of start, stop, and current control into a single foot-operated device frees up the welder's hands to focus entirely on torch manipulation and filler metal addition. Built to Lincoln Electric's high standards, this foot control is a durable investment for any shop looking to maximize the TIG capabilities of their 140 MP or LE31MP units.
