  • Patent number: 10189102
    Abstract: An electric discharge machine includes an electrode, a shaft-feed driving unit that, a voltage/current applying unit, a shaft-feed control unit that causes the shaft-feed driving unit to perform a jump operation, and a machining-condition setting and changing unit that sets a voltage applied between the electrode and a workpiece and an electric current flowing between the electrode and the workpiece. The machining-condition setting and changing unit determines whether the electric discharge between the electrode and the workpiece stabilizes after the jump operation ends and, in at least a part of a period before determining that the electric discharge stabilizes, sets at least one of the voltage and the electric current to a condition in which electric discharge more easily occurs than in the condition in applying the electric discharge machining.

  • Patent number: 10150175
    Abstract: A gas delivery system delivers a shielding gas from a source through one or more hoses to a torch having a nozzle during welding of a workpiece. A shielding gas controller includes an inlet, an outlet, and at least one valve between the inlet and the outlet. The valve operates in response to a predetermined minimum shielding gas flow set point. The shielding gas controller operates the valve before or after a weld to change the flow of the shielding gas according to the predetermined minimum shielding gas flow set point. A method of welding includes predetermining a flow rate of a shielding gas, predetermining another flow rate of the gas, dispensing the gas at the first flow rate proximate a first weld pool during welding, and dispensing the shielding gas at the second flow rate, different from the first flow rate, during welding of another weld on the workpiece.

  • Patent number: 10144076
    Abstract: Even if a machining gap between a wire electrode and workpiece is in a short-circuit state at a start of machining by a wire electric discharge machine, a high-frequency voltage in a pulse shape is applied and a small current is supplied to an extent that the wire electrode is not fused only in an initial fixed time at the start of machining. Then, the short circuit is released, though instantaneously, and a discharge occurs in that instant and the short circuit state is eliminated by discharge repulsion thereof and therefore, machining can be started.
