Hobart Welding Products OM-474 Run-In Procedure Using Resistance Grid, Do not touch hot exhaust

9-3. Run-In Procedure Using Resistance Grid

			Y Stop engine.
			Y Do not touch hot exhaust
				pipe, engine parts, or load
				bank/grid.
			Y Keep exhaust and pipe away
				from flammables.
			1	Resistance Grid
			Use grid sized for generator rated
			output.
			Turn Off grid.
			2	Welding Generator
6			Place A/V range switch in maxi-
			mum position, A/V control in mini-
			mum position, and Output Selector
			switch (if present) in either DC
	2	1	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
			minutes.
			Set grid switches and then adjust
			generator A/V control so load
	5		equals rated generator output (see
3			nameplate).
4			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.
