Abstract

The welding device of the present invention includes: a housing with detachable side plates; a partition member that divides the housing into a plurality of regions; a cooling fan unit housed in the housing; and a cooling fan unit housed in the housing and adjacent to the cooling fan unit. cooling unit. The cooling unit is in the shape of a tunnel opened in the air supply direction of the cooling fan. The heat dissipation unit is attached to the partition plate through the connecting member by using the connecting portion provided on the side surface. The cooling unit can be removed from the welding machine by removing the side panels, and then the connecting parts.

Description
