摘要： In consumable electrode type gas shielded arc welding, a time second order differential value of a welding voltage or an arc resistance is calculated. Based on the second order differential value, a detachment of a droplet or a timing just before the detachment is detected. After the droplet detachment or the timing just before the detachment is detected, a welding current value is immediately switched to a predetermined current value lower than that at the time of the detection. According to the control, even if welding conditions are changed or wire extension lengths are changed in the welding, the droplet detachment can be correctly detected.

摘要： In a pulsed arc welding method of the invention, a shield gas made mainly of carbon dioxide gas is used, and a low frequency pulse of 30 to 100 Hz is continuously generated, on which a high frequency pulse with a pulse frequency of 500 to 2000 Hz is superimposed. In this case, the welding current is determined such that an average peak current IPavg is at 300 to 700 A, an average base time Tb is at 5 to 30 ms, a current amplitude IP-a at a peak time of a high frequency pulse is at 50 to 600 A, and a current amplitude IPb at a base time of a high frequency pulse is at 20 to 200 A. This method ensures a reduced degree of biasing of a drop and an arc, for which the size, release time and release direction of a drop are kept substantially completely constant, and can achieve drop transfer wherein regularity of one pulse group-one drop transfer is very high. Hence, spatter and fume generation rates can be remarkably reduced.

摘要： A pair of solenoids are disposed coaxially with and around a hollow cylindrical cut-off valve. The valve includes an inner non-magnetic sleeve and an outer permanent magnet sleeve. The cut-off valve slidably engages a fuel distributing plunger which injects fuel according to its axial reciprocation. The cut-off valve controls fuel injection quantity via timing of exposure of a fuel injection cut-off port in the plunger. When the pair of solenoids are energized in accordance with operating parameters of the engine, the cut-off valve is moved to a corresponding position along the plunger. A sensor senses the actual position of the cut-off valve for feedback control thereof. A pair of disc-like permanent magnets may be disposed opposite either extreme of travel of the cut-off valve in spaced relationship thereto. A pair of non-magnetic discs may be disposed in place of the pair of disc-like permanent magnets. A biasing member may be disposed between the cut-off valve and the plunger housing to prevent the cut-off valve from being attracted by the plunger housing and for preventing rotation of the cut-off valve relative to the plunger housing. The biasing member may be diaphragm, coil spring or a leaf spring.
