A strapping tool for tensioning overlapping sections of steel strap around a load and forming a notch-type seal in a seal element positioned over the overlapping sections of steel strap includes a body having a foot, a tensioning section and a sealing section. The tensioning section has a tensioner motor assembly operably mounted to the body. The tensioner motor assembly has an electrically powered tensioner motor. A tensioning wheel is operably connected to the tensioner motor. The sealing section has a notcher assembly that includes an electrically powered notcher motor operably mounted to the body. The notcher assembly includes a linkage and at least one pair of jaw elements. The linkage is configured to pivot ends of the jaw elements toward one another in a sealing cycle to form the notch-type seal in the seal element. A control system controls operation of the tensioner motor and the notcher motor. The control system is configured to operate the strapping tool in an automatic mode in which the tensioner motor and the notcher motor are sequentially actuated by action of the control system by an operator.
