SAFETY APPARATUS OF INVERTER WELDING MACHINE

摘要

PURPOSE: A safety apparatus of inverter welding machine is provided in which driving state of an engine is controlled so that the inverter welding machine is safely used. CONSTITUTION: The safety apparatus of inverter welding machine comprises a switch(10) capable of regulating overvoltage delay time according to operation of a user; a control part(40) for having at least one or more data for overvoltage delay time, setting the overvoltage delay time as one of the stored data for overvoltage delay time by responding to signals inputted from the switch, counting the overvoltage delay time when an engine is operated by the user, and impressing a welding power source after a lapse of delay time, wherein the safety apparatus of the inverter welding machine further comprises a temperature sensing part(20) for outputting different signals when the engine is in the overheated state or not in the overheated state by measuring temperature of an engine for the inverter welding machine, and an input voltage sensing part(30) for outputting different signals in case that low voltage or normal voltage is inputted by checking supply voltage inputted from the inverter welding machine.
