            No elaborate procedure, just select process and weld!

            Meter Maintenance Displays

            • Fuel gauge.
            • Hour meter function.
            • Oil change interval.
            • High coolant temperature and low oil pressure shut downs.
            • Low fuel shutdown - engine shuts down before system runs out of fuel, making restarts easy.

            Auxiliary Power*

            • 2 X 15 Amp Sockets.
            • 1 X 32 Amp Sockets.
