Document Type and Number:
WIPO Patent Application WO/2018/079153
Kind Code:
A1
Abstract:
Provided is a laser machining device comprising: noise suppression devices (6, 7) to which a commercial power supply is fed via a breaker (4), and which suppress noise included in the commercial power supply; a power supply circuit (8) which generates a power supply voltage on the basis of the commercial power supply fed from the noise suppression devices (6, 7), and which feeds the power supply voltage to an internal circuit (9); and a step-down insulation transformer (5) which is interposed at a position between the breaker (4) and the power supply circuit (8), and which steps down the voltage of the commercial power supply.
