The Foot Amptrol comes with a generous 25 ft. (7.6m) cable and a convenient 6-pin connector. Designed for effortless current control, simply depress the pedal to increase the current, while fully depressing the pedal will reach the maximum set current. When you fully raise the pedal, it completes the welding process and initiates the Afterflow cycle. Additionally, this foot control accessory is equipped with an optional heel rest for enhanced comfort.
