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： A welding control method for a welding device having an output characteristic with a predetermined gradient showing a relation between a welding output voltage and a welding output current. By setting a set target welding voltage that is higher than the set initial welding voltage according to a difference between the set initial welding voltage and the welding output voltage, the welding output voltage is controlled to be the set target welding voltage. Thus, a proper arc length can be achieved early by correcting the change of the arc length due to, for example, motion of the hands of a welding operator.

摘要： A torch is moved by a manipulator in a direction separating from a base material 7 while a wire is supplied, whereby an actuator driving the robot manipulator can control a velocity of the wire for a workpiece by a unidirectional operation of separating the torch, and vibration due to reverse of torch velocity is not generated. Further, by using a dedicated separation control system, velocity follow-up performance of the actuator moving the torch can be heightened without increasing overshoot in the usual operation time, and the acceleration and deceleration time of the manipulator can be reduced.
