MODULAR WELDING MACHINE

Disclosed is a modular welding machine which can effectively recover heat generated from each individual welding machine, by applying a lightened and simplified water-cooled cooling structure. The modular welding machine is provided in a plural number to perform a plurality of welding processes in multi positions, wherein each of component parts configuring the welding machine is modularized into groups to thereby be configured on a single panel and is installed within a single case. In addition, the modular welding machine can perform a plurality of welding processes in multi positions and comprises a plurality of individual welding machine modules, in each of which a cooling plate according to a water-cooled method is installed, the cooling plate having a flow path in which the cooling water circulates for cooling the heat-radiating parts. Therefore, a micro-miniature and micro-light water-cooled modular welding machine can be manufactured with approximately at least 20 % increased welding power efficiency by circulating stable cooling water to each water-cooled individual welding machine module to prevent heat generation of a welding machine power conversion element, and with omitting an air-cooled heat-radiating part which takes 70 % of the entire volume of an air-cooled module welding machine.
