10-3. Run-In Procedure Using Resistance Grid
S-0684
! Stop engine.
! Do not touch hot exhaust
pipe, engine parts, or load
bank/grid.
! Keep exhaust and pipe away
from flammables.
NOTICE − Do not perform run-in
procedure at less than 20 volts weld
output and do not exceed duty
cycle or equipment damage may
occur.
1
Resistance Grid
Use grid sized for generator rated
output.
Turn Off grid.
2
Welding Generator
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 V/A control so load
equals 225 amps at 30 volts.
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.
It is recommended to run the weld-
ing generator for two hours mini-
mum and up to four hours under
load. Place V/A control in minimum
position, then shut down grid to
remove load. Run engine several
minutes at no load.
! Stop engine and let cool.
6 Engine Exhaust Pipe
