Section 10-2).
2
AC Receptacles RC1, RC2,
And RC3
Move throttle lever to correct
position (50 or 60 Hz) for generator
power. Check voltage at each
receptacle. With no load applied,
voltage should be 10% above
receptacle rating on nameplate.
EXAMPLE: Correct no load voltage
for a 120 volt receptacle should be
132 volts ac.
If generator power or weld output
voltage is incorrect, adjust engine
speed (see Section 7-4 or 7-5).
