INSTALLATION OF SETTING-UP INSTRUCTIONS.
a.
General. Power for operation of the shop set may come from either
of two Sources : The shop set engine driving the dynamotor-welder
or an external power source of 240 volts, 3phase, 50 or 60cycle

area required by the shop set proper is approximately 40 x 25 ft.
The location of the shop set must provide such additional cleared
