    摘要： Embodiments of a welding power supply include an engine adapted to drive a generator to produce a first power and a energy storage device adapted to discharge energy to produce a second power. The welding power supply also includes control circuitry adapted to detect a commanded output. The control circuitry is adapted to meet the commanded output by controlling access to power from the energy storage device to produce the second power when the commanded output is below a first predetermined load level. The control circuitry is further adapted to meet the commanded output by controlling access to power from the engine and the energy storage device to produce the first power and the second power when the commanded output is above a second predetermined load level.

    摘要： A pulse arc welding device is controlled so as to weld an object by removing, from a welding wire, a molten droplet produced by melting the welding wire by applying a welding voltage between the welding wire and the object and allowing a welding current to flow through the welding wire such that the welding current alternately repeats, at pulse frequency, a peak current period in which the welding current is a peak current and a base current period in which the welding current is a base current smaller than the peak current. A removal time point at which the molten droplet is removed from the welding wire is determined. In a case where the removal time point is not in the base current period, a pulse waveform parameter which is at least one of the peak current and the peak current period is adjusted, and the pulse frequency based on a predetermined relationship between the pulse frequency and the pulse waveform parameter is adjusted so as to cause the removal time point to be in the base current period. This method allows a stable pulse arc welding.

    摘要： A penetration welding method includes a plasma welding step for forming a through hole in a work, which is a laminated steel plate, from a front surface to rear surface thereof without forming a hole in a component at the rear, by generating a plasma arc column from a plasma torch to the work. After the plasma arc column is generated, the plasma arc column is extinguished when an arc voltage or the length of the arc estimated from the arc voltage exceeds an end-determining threshold which is determined according to the thickness of the work. Further, plasma gas is discharged from the plasma torch at a flow rate at which the width of the plasma arc column is maintained approximately constant from the plasma torch side to the work side so that the arc voltage is increased at an approximately constant rate before and after penetration.
