A power tong combination having a tong head for threaded pipe adapted to be driven in opposite pipe gripping and turning directions by a driving system which (1) drives only a first motor at a preselected torque and at high speed in the direction to connect threaded pipe: (2) jointly drives the first motor and a second motor to produce increased yet controlled torque to finally make up a pipe joint, and (3) jointly drives both motors to provide high torque to break out a pipe joint and then drives only the first motor to provide less torque and high speed to rapidly disconnect the pipe joint whereby the pipe gripping means remains engaged with pipe during the foregoing changes in speed and torque.
