To make the installation simple, the owner used the mower's existing steel floor/frame plate, to which the mower engine was already attached, as the mounting mechanism for the welding power generator as well (see side views). All that had to be done was to cut a hole to accommodate the power generator's pulley and fan and drill a couple of holes to rigidly mount the power generator to the floor plate. V-belt tension is adjusted by means of an idler pulley which was used in the mower.
A metal frame was made from 3/4" square (1/8" wall) steel tubing to enclose the welder and to provide a mechanism for mounting the engine/power generator, the mower's old gas tank, the mower's battery, starter solenoid, and starter switch. The frame also serves as a mechanism for keeping welding cables organized
A piece of sheet metal was used to provide a bit of protection from the elements to the welding power generator and battery -- and to dress up the completed unit.
The well satisfied owner reports that this weekend project was completed on schedule -- and that the total cost of his finished welder was less than $700.
He also plans to add an external voltage regulator and use the unit for quick charging batteries.
