A power source apparatus for supplying electrical power for an arc welder includes a frame having a base member and first and second pairs of support members each defining an inverted V-shaped configuration mounted to the opposite side edges of the base member. An inverted channel cross member extends transversely between the upper ends of the support members. The support members each define a U-shaped channel having a pair of sidewalls and a connecting wall therebetween and are oriented such that the connecting walls face away from each other. An associated assembly method includes the steps of adjoining the ends of first and second pairs of support members and connecting them with a cross member to define a frame subassembly. At least a portion of the power circuit of the arc welder power source is then mounted on the frame subassembly before it is attached to the power source frame. A busbar assembly for supporting two rows of capacitors in parallel on the frame of an arc welder is also provided. A fan assembly for generating an airstream through the power source is also provided and includes a frame mounted to the power source defining at least two opposed recessed portions.
