摘要： Embodiments described herein provide methods and hybrid welder devices including a housing, an alternating current (“AC”) power input, a battery pack interface, a welding circuit, and an electronic controller. The housing including the battery pack interface and the AC power input. The battery pack interface receives a removable battery pack. The AC power input receives power from an AC power source and output an AC power output. The welding circuit provides power to a welding electrode using the AC power input. The electronic controller connected to the AC power source and the removable battery pack. The electronic controller receives power from the AC power source and determines whether the power from the AC power source exceeds a maximum power output threshold. The electronic controller also supplements the power provided to the welding circuit with power from the removable battery pack in response to the power exceeding the maximum output threshold.

摘要： A reciprocating saw includes a housing, a motor, and a drive mechanism. The motor includes an output gear rotatable about a motor axis. The drive mechanism includes a driven gear that engages the output gear and is rotated by the motor. The driven gear has a circumference and is vertically-oriented within the housing. The drive mechanism also includes an output shaft coupled to the driven gear and configured to reciprocate relative to the housing. The drive mechanism further includes a single counterweight fixed relative to the driven gear and rotating with the driven gear through a path and in a same direction. As the counterweight moves through a rearward half of the path, the counterweight generally moves in an upward direction, and as the counterweight moves through a forward half of the path, the counterweight generally moves in a downward direction.

摘要： A drain clearing air gun includes a housing defining a main body, a handle positioned on a first end of the main body, and a nose positioned on a second end of the main body. A tank is at least partially positioned within the housing and includes a chamber for receiving pressurized air. A motor is positioned within a main body of the housing, and a pump is positioned within the main body of the housing and operatively coupled to the motor. The pump is driven by the motor to pump air into the tank. A pressure gauge is supported by the housing and includes an automatic shutoff feature. The pressure gauge is in fluid communication with the tank. When a predetermined pressure within the tank is reached the automatic shutoff feature is activated to stop the motor.

摘要： A reciprocating saw includes a housing, a motor, and a drive mechanism. The motor is configured to operate in a forward mode corresponding to a first rotational direction, and in a reverse mode corresponding to a second rotational direction opposite the first rotational direction. The drive mechanism includes a driven gear, a connecting rod, an output shaft, and a counterweight. The driven gear is rotated by the motor and has an upper portion and a lower portion. The output shaft reciprocates through a cutting stroke and a return stroke. The counterweight is coupled to the driven gear and rotating with the driven gear. When the motor is operated in the forward mode, the counterweight moves through the upper portion of the driven gear during the cutting stroke of the output shaft, and moves through the lower portion of the driven gear during a return stroke of the output shaft.

摘要： A tool support includes a frame that is configured to support a tool and a powered track supported on the frame. The powered track includes a drive roller, an idler roller, and an endless belt that extends around the drive roller and the idler roller. The tool support also includes a first motor supported on the frame. The first motor is operable to drive the drive roller and rotate the endless belt. The tool support further includes a second motor supported by the frame. The second motor is configured to be coupled to the tool to drive the tool supported on the frame.

摘要： A power tool includes a housing, a motor, and a drive mechanism. The drive mechanism includes a driven gear that is rotated by the motor. The driven gear is vertically-oriented within the housing and has an upper portion and a lower portion. The drive mechanism also includes a connecting rod coupled to the driven gear to translate rotary motion of the driven gear into reciprocating motion, and an output shaft coupled to the connecting rod to reciprocate relative to the housing through a cutting stroke and a return stroke. The drive mechanism further includes a counterweight coupled to the driven gear for rotation with the driven gear. The counterweight moves through the upper portion of the driven gear during the cutting stroke of the output shaft, and moves through the lower portion of the driven gear during a return stroke of the output shaft.

摘要： A drain cleaner assembly including a base unit having a housing, a first portion of a drive arrangement supported by the housing, and a motor coupled to the drive arrangement, where the motor is operable to selectively drive the drive arrangement. A drum unit is removably coupled to the base unit. The drum unit includes a rotatable drum, a cable stored within the drum and selectively extendable out of the drum and into a drain, and a second portion of the drive arrangement, where the second portion of the drive arrangement includes a driven shaft extending along an axis of rotation of the rotatable drum, where the driven shaft is rotatably fixed to the rotatable drum, and wherein the first portion of the drive arrangement is configured to drive the driven shaft and the rotatable drum when the drum unit is coupled to the base unit.

摘要： A drain cleaning device including a drum, a cable positioned within the drum, a motor coupled to the drum to rotate the drum, a cable feed device operable to extend the cable out of the drum and retract the cable into the drum, a sensor operable to detect a performance characteristic of the drain cleaning device, and a controller coupled to the sensor and to the motor, the cable feed device, or both. The controller is configured to receive a signal from the sensor indicative of the performance characteristic of the drain cleaning device, and send an instruction to the motor, the cable feed device, or both to change an operating parameter of the motor, the cable feed device, or both based on the signal received from the sensor.
