Heavy Duty Square D FIVE WIRE Foot Pedal Switch double clicks 6006

  For sale is a Heavy Duty Square D Five Wire Foot Pedal Switch TIG
control? I am not sure what it does. It clicks twice as the pedal is
engaged to the max. Very expensive. See
http://ecatalog.squared.com/fulldetail.cfm?partnumber=9002AW2 for
comparison. Shipping can be combined.
