A mid-plane baffle or plate having a fan mounted thereto to dissipate heat within a welding machine is provided. By centrally positioning a baffle and mounting a circulating fan thereto, cooling efficiency is improved thereby enabling more direct cooling of the internal components of the welding machine. The baffle also reduces the critical volume of the welding machine and allows the fan to operate more efficiently and pull an increased amount of cooler ambient air through the machine which creates a greater cooling effect during the cooling cycle of the machine. The baffle placement also improves welding start performance by operating as a barrier between the high frequency/high voltage components and the PC board (control electronics) of the welding machine. The baffle also improves flexibility of component placement within the welding machine.
