Location / Ventilation
Always operate the welder with the doors closed.
Leaving the doors open changes the designed air flow
and may cause overheating.
The welder should be located to provide an unrestrict-

that engine exhaust fumes are properly vented to an
outside area.

Auxiliary Power
The AC auxiliary power, supplied as standard, has a
rating of 3.0 kVA of 120 VAC (60 hertz).
With the 3.0 kVA, 120 VAC auxiliary power for Code
10567, one 120V duplex grounding type receptacle is
provided. The circuit is protected with circuit breakers.
Codes 10956, 11214 and 11488 uses one GFCI with
breaker.
The rating of 3.0 kVA permits a maximum continuous
current of 26 amps that can be drawn from the 120
volt duplex receptacle. The 120 volt duplex receptacle
or GFCI has a configuration which permits 20 amps to
be drawn from either half. The total combined load of
the duplex receptacle or GFCI is not to exceed 3.0
kVA.
If a GFCI receptacle is tripped, See the MAINTE-

MAINTENANCE

GFCI RECEPTACLE TESTING AND RESET-
TING PROCEDURE
The GFCI receptacle should be properly tested at
least once every month or whenever it is tripped. To
properly test and reset the GFCI receptacle:
鈥? If the receptacle has tripped, first carefully remove
any load and check it for damage.
鈥? If the equipment has been shut down, it must be
restarted.
鈥? The equipment needs to be operating at high idle
speed and any necessary adjustments made on the
control panel so that the equipment is providing at
least 80 volts to the receptacle input terminals.
鈥? The circuit breaker for this receptacle must not be
tripped. Reset if necessary.
鈥? Push the "Reset" button located on the GFCI recep-
tacle. This will assure normal GFCI operation.
鈥? Plug a night-light (with an "ON/OFF" switch) or other
product (such as a lamp) into the GFCI receptacle
and turn the product "ON".
鈥? Push the "Test" button located on the GFCI recepta-
cle. The night-light or other product should go
"OFF".
鈥? Push the "Reset" button, again. The light or other
product should go "ON" again.
If the light or other product remains "ON" when the
"Test" button is pushed, the GFCI is not working prop-
erly or has been incorrectly installed (mis-wired). If
your GFCI is not working properly, contact a qualified,
certified electrician who can assess the situation,
rewire the GFCI if necessary or replace the device.

(1) FLASHING THE FIELDS:
1. Stop the engine welder and remove the cover from the exciter.
2. Turn the 鈥淔ine Current Adjustment鈥? (rheostat) to 鈥?100鈥? on the dial.
3. Using a 12 volt automotive battery, connect it始s negative terminal to the negative brush holder.
The negative brush holder is the one nearest to the rotor lamination. See the wiring diagram. With
the engine NOT running, touch the positive battery terminal to the positive brush holder. Remove
the battery from the circuit.
