Abstract: An inverter type water-cooled single welding machine module. The welding machine module contains a plurality of inverter welding machines embedded inside one case. As a part of measures to reduce size and lighten the weight of each individual welding machine, the conventional air-cooled method of using fans is replaced with a water-cooled method. The individual welding machines can be manufactured to be smaller and lighter by drastically reducing the size of the individual welding machines (in the order of ? to ?) due to effects of decreasing the number of heat dissipation components to be used and reducing the capacity and size thereof through efficiency enhancement of the heat dissipation components.

Abstract: A modular welding machine effectively recovers heat generated from each individual welding machine by applying a lightened and simplified water-cooled cooling structure. A plurality of the modularized welding machines is provided to perform multiple welding processes in multi-positions. Each component parts of the modularized welding machine is modularized into groups to be configured on a single panel and installed within a single case. The modular welding machine can perform multiple welding processes in multi-positions and includes a plurality of individual welding machine modules. A water-cooled cooling plate is installed in each module. The cooling plate has a flow path in which the cooling water circulates for cooling the heat-radiating parts.
