Abstract
A control pedal for a welder that controls the output current level of the welder. The control pedal includes a foot pedal, a start switch, and a current level controller. The foot pedal is movable between an off position, an intermediate position, and a fully on position. The start switch initiates a startup sequence for the welder. The current level controller produces a signal that causes the output current level of the welder to vary between a minimum and a maximum current level. The foot pedal causes the start switch to begin the startup sequence prior to the foot pedal causing the current level controller to generate a signal which results in the output current level increasing above the minimum current level.
