Miller Electric Big Blue 400 KX manual Run-In Procedure Using Resistance Grid, Bank/grid

10-3. Run-In Procedure Using Resistance Grid

		Y Stop engine.
		Y Do not touch hot exhaust
			pipe, engine parts, or load
			bank/grid.
6		Y Keep exhaust and pipe away
			from flammables.
	2	Y Do not perform run-in
			procedure at less than 20
			volts weld output and do not
			exceed duty cycle or equip-
			ment damage may occur.
		1	Resistance Grid
		Use grid sized for generator rated
		output.
	1	Turn Off grid.
		2	Welding Generator
		Place V/A control in minimum posi-
		tion, and Output Selector switch (if
		present) in either DC position.
		3	Weld Cables
		Connect grid to generator weld
		output terminals using proper size
		weld cables with correct connec-
		tors (polarity is not important).
		4	Voltmeter
		5 Clamp-On Ammeter
		Connect voltmeter and ammeter as
		shown, if not provided on generator.
		Start engine and run for several
3	5	minutes.
		Set grid switches and then adjust
		generator A/V control so load
		equals rated voltage and current of
		the generator (see nameplate, rat-
		ing label, or the specifications sec-
4		tion in this manual).
		Check generator and 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 shut down grid to remove load.
		Run engine several minutes at no
		load.
		Y Stop engine and let cool.
		6	Engine Exhaust Pipe
		Repeat procedure if wetstacking is
		present.
