PEX expansion tool

An expansion tool comprising:

• a housing;
• a motor supported within the housing;
• a mandrel;
• a drive mechanism configured to convert a rotational input from the motor into translational movement of the mandrel, the drive mechanism including a cam and a drive shaft coupled to the cam;
• a frame including a hub and a neck extending from the hub, the neck having an opening;
• a working element coupled to the neck and including a plurality of jaws movable from a closed position toward an expanded position in response to movement of the mandrel from a retracted position toward an extended position;
• a first operating mode;
• and
• a second operating mode,
• wherein the mandrel extends through the opening to engage the jaws,
• wherein the drive shaft is rotatably supported by the hub,
• wherein the drive mechanism is configured to reciprocate the mandrel between the retracted position and a first extended position when the expansion tool is operated in the first operating mode,
• wherein the drive mechanism is configured to reciprocate the mandrel between the retracted position and a second extended position different than the first extended position when the expansion tool is operated in the second operating mode, and
• wherein the expansion tool further comprises a controller configured to switch between the first operating mode and the second operating mode in response to ambient temperature.
