GAS-SHIELDED FLUx-CORED
WELDING
(with a K623-1 Wire Feed Module installed)
Start by setting the Wire (CV) / Stick (CC) toggle switch
to the Wire (CV) position. Then set the left-side Coarse
Current control dial to 150. Now move the Voltage
Adjustment dial to the desired voltage.
Coarse Current control to the left for a softer arc and to
the right for a crisper arc.

MIG WELDING

(with a K623-1 Wire Feed Module Installed)
Start by setting the Wire (CV) / Stick (CC) toggle switch
to the Wire (CV) position. Then set the left-side Coarse
Current control dial to 150. Now move the Voltage
Adjustment dial to the desired voltage.
Coarse Current control to the left for a softer arc and to
the right for a crisper arc.

CARBON ARC GOUGING

Set both the Coarse Current and Fine Current O.C.V
controls to maximum for carbon arc gouging in the CC
(constant current) mode.
Module is installed and the CV (constant voltage)
mode is desired, set the Wire (CV) / Stick (CC) toggle
switch to the Wire (CV) position. Then set the left-side
Coarse Current control to maximum output and the
Voltage Adjustment dial to maximum output.
IDLER OPERATION
Start the engine with the "Idler" switch in the "High"
position. Allow it to run at high idle speed for several
minutes to warm the engine. See Specifications for
operating speeds.
The idler is controlled by the "Idler" toggle switch on the
welder control panel. The switch has two positions as
follows:
Low Idle (1375 RPM)-No Load @ 45 Volts
High Idle (1800 RPM)-No Load @ 96.6 Volts
250 Amps @ 30 Volts
300 Amps @ 32 Volts

1. In the "High" position, the idler solenoid deac-
tivates and the engine goes to high idle speed. The
speed is controlled by the governor.
2. In the "Auto" /
ates as follows:
a. When welding or drawing power for lights or
tools (approximately 100 watts minimum) from
the receptacles, the idler solenoid deactivates
and the engine operates at high idle speed.
b. When welding ceases or the power load is
turned off, a preset time delay of about 15 sec-
onds starts. This time delay cannot be adjust-
ed.
c. If the welding or power load is not re-started
before the end of the time delay, the idler sole-
noid activates and reduces the engine to low
idle speed.

AUxILIARY POWER

If GFCI is tripped, See the MAINTENANCE section
for detailed information on testing and resetting the
GFCI.
The AC auxiliary power, supplied as a standard, has a
rating of 3.0 KVA of 115/230 VAC (60 hertz).
With the 3.0 KVA, 115/230 VAC auxiliary power, one
120V duplex protected by GFCI and one 230V duplex,
grounding type receptacle with 2 pole, 15 amp circuit
breaker.
The rating of 3.0 KVA permits a maximum continuous
current of 13 amps to be drawn from the 230 volt
duplex receptacle. 20 amps can be drawn from the 120
volt duplex receptacle. The total combined load of all
receptacles is not to exceed 3.0 KVA.
An optional power plug kit is available. When this kit is
specified, the customer is supplied with a plug for each
receptacle.
