摘要： A push-pull welding wire feeder includes plural wire feeding units provided in a wire feeding passage extending from a welding wire magazine, in which a roll of welding wire is accommodated, via a wire guide tube to a welding torch. At least one of the wire feeding units includes a torque limiter provided in a driving transmission system thereof for transmitting a driving force from a driving source to the welding wire. Accordingly, the welding wire feeder can steadily convey the welding wire even at acceleration or deceleration while allowing the welding wire to be bent, thus contributing to favorable result of its welding operation.

摘要： An arc welding method relates to consumable electrode arc welding in which a welding wire feeding rate suitable for a welding current is determined as an average feeding rate, and the short circuit state and the arc generation state are alternately generated by changing the wire feeding periodically and repeatedly between the forward feeding and the reverse feeding. The method offers arc welding with the average feeding rate according to a welding current, a predetermined frequency, and a predetermined velocity amplitude. In the method, at least any one of the frequency and the velocity amplitude is set to a value suitable for the welding current.

摘要： An arc welding method of the present invention controls a short-circuit current increasing gradient (di/dt), an inflection point at which the short-circuit current increasing gradient (di/dt) changes, the current in a peak period and in a base period, and the time of the peak period in accordance with a difference between a set voltage and an output voltage. This allows the output voltage to be matched with the set voltage, and stabilizes the arc. Thereby, a stable arc welding method can be implemented, even as a method for outputting a welding current based on a welding voltage.

摘要： In the conventional arc welding control unit, since the air of the outside of the equipment is applied directly to the whole of the main semiconductor for cooling, there is found a problem that dust, welding fumes and the like can accumulate on or adhere to the conductive portions of the inside of the equipment, which takes time for maintenance of the equipment. To solve this, according to the invention, there is provided an arc welding control unit having a heat radiating unit built in the box body thereof for discharging the air heated by a heat generating first electrical element to the outside. The heat radiating unit has a tunnel-type shape including an outer peripheral portion for defining a cavity portion allowing the air to flow therethrough, whereby dust, welding fumes and the like can be prevented from accumulating on or adhering to the conductive portions of the inside of the equipment.

摘要： When either a command value or an actually measured value is appropriately selected as an angular velocity used for the frictional torque calculation, the frictional compensation can be made valid at all times in both the case in which a robot is actively operated according to an angular velocity command and the case in which the robot is passively operated being pushed by an external force. In the case where a motor rotating direction and a collision direction are reverse to each other after a collision has been detected, the control mode is switched from the positional control to the electric current control and a torque, the direction of which is reverse to the direction of the motor rotation is generated by the motor, so that the motor rotating speed can be reduced and the collision energy can be alleviated. After that, when the motor rotating speed is reduced to a value not more than the setting value, the control mode is switched to the compliance control and the distortion caused in a reduction gear is dissolved. On the other hand, in the case where the motor rotating direction and the collision direction are the same, the control mode is directly switched from the positional control to the compliance control without passing through the electric current control. When the robot is operated whole following a collision force, the collision force can be alleviated.
