摘要： An end cap (24) is formed as a substantially cylindrical body having substantially the same diameter as an external diameter of a retaining unit (60) of an oscillation fibre (22); a base end surface (24a) is integrally fusion-welded or fusion-bonded to one end surface (22a) of the oscillation fibre (22); and a leading end surface (24b) is obliquely cut relative to the light axis. A returning oscillating beam reflected by an optical resonator mirror (34) is converged and made incident on a core end surface (60a) of the oscillation fibre (22) located at a focus position of an optical lens (28). However, since the core end surface (60a) is integrally bonded with the end cap (24) and is not exposed to the atmosphere, the core end surface is not burned or deteriorated (60a) by the light energy of the oscillating beam.

摘要： A capacitor (12) has a positive electrode (12a) that is electrically connected to a welding electrode (14) on one hand by way of a switching transistor (18) for the supply of welding current and has a negative electrode (12b) that is electrically connected to a welding electrode (16) on the other. The capacitor (12) is charged by a charging circuit (30). A charging control unit (50) accepts as a charging voltage monitor signal an output signal of a comparator (54) and provides a control of the charging circuit (30) so as to allow a capacitor voltage V g fed to one input terminal of the comparator (54) to conform to a set voltage V s fed by a main control unit (28). This power supply apparatus includes two designation modes, i.e., a direct designation mode in which the user directly designates a desired capacitor voltage, and an indirect designation mode in which the user designates a standard current value as a provisional standard for a welding current I w so that the apparatus can automatically set a capacitor voltage corresponding to the standard current value designated.

摘要： A control unit first enters a schedule No. (code) desired by a user for a given workpiece (step B 1 ). The control unit then identifies the entered schedule No. to read set values of various working conditions being managed by that schedule No. from a memory, and sets them into predetermined registers (steps B 2 , B 3 ). Working condition set values in an associated work section are particularly set (step B 4 ). Then, in response to a start signal from an external device or to a start signal input by the user, the control unit executes a single fusing work (steps B 5 , B 6 ). After completion of the single fusing work, the control unit increments a section work point counter by one (step B 7 ). Then, until reaching the set count of the work points defined in that section, the control unit reiterates the fusing work on the subsequent work points in totally the same working conditions as the above (steps B 8 → B 4 to B 7 → B 8 ).

摘要： This power supply apparatus comprises a charging circuit (30) for charging a capacitor (12). The charging circuit (30) includes a transformer (32), a rectifying circuit (34), a switching element (36), an inductance coil (38) and a freewheeling diode (40). The rectifying circuit (34) full-wave rectifies an AC power supply voltage E 1 acquired on the secondary side of the transformer (32) to provide a DC voltage as its output. When the switching element (36) is turned on or becomes conductive, a DC current I c is allowed to flow through a circuit (43) extending from a positive output terminal (34a) of the rectifying circuit (34) through the switching circuit (36) and the inductance coil (38) to a negative output terminal (34b) of the rectifying circuit (34). Once the switching element (36) is switched from its ON state to OFF state, a current I d based on the inductance coil (38) flows in the forward direction of the diode (40) through a closed circuit (46) consisting of the inductance coil (38), capacitor (12) and the diode (40) such that the capacitor (12) is charged with the freewheeling current I d .

摘要： When a second switching element Q 2 is changed over from ON state to OFF state for each switching cycle while a first switching element Q 1 remains ON in a unit weld period T a for example, a primary current I 1 does not come to a stop at once under the influence of inductance of a welding transformer 16 but it flows as a transient current i through a primary circuit until it is off. The transient current i makes a closed circuit through which it flows from a primary coil of the welding transformer 16 via a third diode D 3 and then a first switching element Q 1 again into the primary coil of the welding transformer 16. More specifically, due to the first switching element Q 1 being kept ON, the transient current i which has passed through the third diode D 3 flows through the first switching element Q 1 , without passing through a capacitor 12, and comes back into the primary coil of the welding transformer. Little or substantially no current flows through the capacitor 12.
