CASE FOR AN INVERTER ARC WELDER AND A MANUFACTURING METHOD THEREOF, CAPABLE OF IMPROVING MAINTAINABILITY AND WORKABILITY

摘要

PURPOSE: A case for an inverter arc welder and a manufacturing method thereof are provided to improve the cooling performance of the inverter arc welder while a cooling fan discharges the air in the case to outside.;CONSTITUTION: A case(1) for an inverter arc welder comprises a main body(10), first sub body(20), and a second sub body(30). The main body is formed by pressing. First bending portions(11) are integrally and respectively formed in the left and right sides of the main body. First, second and third parts(13,25,35) are mounted to each upper surface of the main body and first/second sub bodies. The firs sub body is integrally formed in front of the main body. A plurality of first connecting portions(21) and first openings(23) are formed in a part of the first sub body connected to the main body in order to selectively and vertically build the first sub body. The second sub body is integrally formed in a rear part of the main body. A plurality of second connecting portions(31) and second openings(33) are formed in a part of the second sub body connected to the main body in order to selectively and vertically build the second sub body.;COPYRIGHT KIPO 2012
