A small profile strapping tool includes a body defining a cylinder housing, a piston disposed within a cylinder in the cylinder housing, a pneumatic weld motor operably connected to the piston for actuation during a weld cycle, a pneumatic tensioning motor for actuation during a tensioning cycle, and a pneumatic module removably mounted to the cylinder housing. An ATE system includes memory having a test application stored therein, a test interface to connect to the device, and a processor coupled to the memory and the test interface. At least one light emitting diode pulsed by an electronic circuit, which LED is powered by a battery within the battery pack. The compound container formed by the upper and the lower half body presents esthetic feeling caused by its outer solid profile and increases its commercial value.
