K4986-1 - Lincoln Electric Wireless TIG Foot Pedal Control K4986-1

Advanced Wireless Control for Precision TIG Welding

The Lincoln Electric K4986-1 Wireless Foot Pedal sets a new standard for TIG welding accessories, offering professional welders the ability to control amperage precisely without the tether of a control cable. Designed to replace the K4217-1, this updated unit utilizes advanced wireless technology to maintain a robust connection with the power source up to 100 feet (30.5 meters) away. This capability is essential for large fabrication shops, shipyards, and construction sites where long cable runs can be cumbersome, prone to damage, or create significant trip hazards. By removing the control cord, operators can reposition themselves instantly around large weldments without managing cable slack.

Robust Connectivity with Dual-Power Mode™

One of the standout technical features of the K4986-1 is its Dual-Power Mode™. Industrial environments are often saturated with electrical noise and interference from other machinery. This feature allows the pedal to boost its transmission signal, ensuring reliable communication between the foot pedal and the receiver even in challenging conditions. The unit also features a comprehensive LED status display that provides real-time feedback on battery life, welding output status, and signal integrity, allowing the operator to weld with confidence knowing their equipment is functioning optimally.

Ergonomics and Compatibility

Lincoln Electric has engineered this pedal for comfort and versatility. It includes adjustable extension legs that allow the pedal to sit securely on uneven surfaces or be angled for better ergonomic foot positioning during long welding shifts. The receiver unit is powered by an included 120V adapter, while the pedal itself runs on three AA batteries (sold separately). This system is compatible with a wide range of Lincoln power sources, including the Square Wave TIG 175, Precision TIG series, and Invertec models. For newer digital machines like the Power Wave or Flextec series, an additional adapter (K2909-1) enables seamless integration, making this a versatile tool for mixed equipment fleets.
