10-2. Run-In Procedure Using Load Bank

Y Stop engine.

Y Do not touch hot exhaust

pipe, engine parts, or load bank/grid.

Y Keep exhaust and pipe away from flammables.

Y Do not perform run-in procedure at less than 20 volts weld output and do not

4exceed duty cycle or equip- ment damage may occur.

2	1	Load Bank
1	Turn all load bank switches Off. If
	needed, connect load bank to 115
	volts ac wall receptacle or genera-
	tor auxiliary power receptacle.
	2	Welding Generator
	Place Welder Selector switch in
	Welder B position (600 Amps), A/V
	control in minimum position, and
	both Process Selector switches in
	Stick/TIG position.
	3	Weld Cables
	Connect load bank to generator
	Welder B (right) weld output termi-
	nals using proper size weld cables
	with correct connectors. Observe
	correct polarity.
	Start engine and run for several
	minutes.
	Set load bank switches and then
	adjust generator A/V control so load
	equals 350 Amps at 40 volts.
	Check generator and load bank
3	meters after first five minutes then
	every fifteen minutes to be sure
	generator is loaded properly.
	. Check oil level frequently dur-
		ing run-in; add oil if needed.
	After one hour (minimum) place A/V
	control in minimum position, then
	turn off load bank to remove load.
	Run engine several minutes at no
	load.
	Y Stop engine and let cool.
	4	Engine Exhaust Pipe
	Repeat procedure if wetstacking is
	present.
