PURPOSE: An inverter welder is provided to maximize cooling effect of a heat sink and parts installed in the heat sink by concentrating cooling air generated from a blowing fan onto the heat sink. CONSTITUTION: An inverter welder includes a case having a body(11) and a cover(12). A blowing hole(12b) and an air hole(12c) are formed at a sidewall of the cover(12). A blowing fan(14) is installed at an inner portion of the blowing hole(12b). The blowing fan(14) is aligned in opposition to a heat sink(13). When the blowing fan(14) is operated, external air having a low temperature is introduced into the case through the blowing hole(12b) formed at the sidewall(12b) of the case cover(12). External air introduced into the case makes contact with the heat sink(13) so that the temperature of the heat sink(13) drops down.
