Abstract
A strapping tool has a timing control circuit incorporated therein which comprises a first pressure-operable valve for time-controlling a plastic strap welding operation, and a second pressure-operable valve for restricting fluid line flow from a source of fluid to an air drive motor of the tool during the tensioning phase of the strapping operation while permitting unrestricted fluid line flow from the source of fluid to the air drive motor of the tool during the welding stage of the strapping operation.
