SECTION 7 OPERATING AUXILIARY EQUIPMENT
. If the unit is extremely overloaded, weld and generator power will stop. Turn unit off and restart to reset the generator protection circuit and restore
weld generator power output.
. If the rated output of the unit is exceeded, engine speed may vary rapidly until the weld or generator load is reduced.
. The welding generator provides power while welding and with the Amperage control in any position. However, under these conditions equipment
connected to the welding generator may be subject to larger than normal voltage fluctuations. It is recommended that only lamps be powered under
these conditions.
7-1. Standard Receptacles
! If unit does not have GFCI re-
ceptacles, use GFCI-
protected extension cord.
1 120/240 V 50 A AC Recep-
tacle RC1
RC1 supplies 60 Hz single-phase
power at weld/power speed. Maxi-
mum output is 10 kVA/kW.
2 120 V 20 A AC Duplex Recep-
tacle RC2
3 120 V 20 A AC Duplex Recep-
tacle RC3
RC2 and RC3 supply 60 Hz single-
phase power at weld/power speed.
Maximum output from RC2 or RC3
is 2.4 kVA/kW.
4 Supplementary Protector CB1
CB1 protects the ac receptacles
from overload. If CB1 opens, the ac
receptacles do not work.
. Move CB1 toggle switch to On
position to reset. If supplemen-
tary protector continues to
open, contact Factory
Authorized Service Agent.
5 Supplementary Protector CB2
6 Supplementary Protector CB3
CB2 protects RC2 and CB3 pro-
tects RC3 from overload. If a sup-
plementary protector opens, the re-
ceptacle does not work.
. Press button to reset. If supple-
mentary protector continues to
open, contact Factory
Authorized Service Agent.
Combined output of all receptacles
limited to 10 kVA/kW rating of the
generator.
EXAMPLE: If 20 A is drawn from
each 120 V duplex receptacle, only
21 A is available at the 240V
receptacle:
2 x (120 V x 20 A) + (240 V x 21 A)
= 10 kVA/kW (approx.).
