7-2. Description Of Front Panel Controls For CC/CV Models (See Section 7-1)
Engine Starting Controls
1 Magnetic Shutdown Switch
Use switch during start-up to bypass engine
shutdown system. System stops engine if oil
pressure is too low or engine temperature is
too high.
2 Starting Aid Switch
Use switch to energize starting aid for cold
weather starting (see starting instructions fol-
lowing).
3 Engine Control Switch
Use switch to start engine, select engine
speed ( if unit has auto idle option), and stop
engine.
In Run position, engine runs at weld/power
speed. In Run/Idle position (optional), engine
runs at idle speed at no load and weld speed
with load applied.
To Start:
Y Do not use ether. Using ether voids
warranty.
. If engine does not start, let engine come
to a complete stop before attempting re-
start.
Above 325 F (05 C): turn Engine Control
switch to Start while pressing Shutdown
switch. Release Engine Control switch when
engine starts. Continue holding Shutdown
switch until engine indicator lights go out.
Below 325 F (05 C): turn engine control switch
to Run/Idle position. Push Starting Aid switch
up for 60 seconds. While still holding Starting
Aid switch, press Magnetic Shutdown switch
and turn Engine Control switch to Start. Re-
lease Engine Control switch and Starting Aid
switch when engine starts. Continue holding
Shutdown switch until engine indicator lights
go out.
To Stop: turn Engine Control switch to Off
position.
Engine Indicator Lights
4 Battery Charging Light
Light goes on if engine alternator is not charg-
ing battery. Engine continues to run.
Y Stop engine and fix trouble if Battery
Charging light goes on.
5 Engine Temperature Light
Light goes on and engine stops if engine tem-
perature is above 221 ° F (105° C).
Y Stop engine and fix trouble if Engine
Temperature light goes on.
6 Engine Oil Pressure Light
Light goes on and engine stops if oil pressure
is below 5 psi (34 kPa). Light goes on momen-
tarily during start-up but goes out when en-
gine reaches normal oil pressure.
Y Stop engine and fix trouble if Engine
Oil Pressure light stays on after start-
up.
7 Fuel Light
Light is not active on this model.
8 Engine Hour Meter
Engine Gauges
. To read gauges and engine indicator
lights with engine off, turn Engine Control
switch to Run/Idle and press Magnetic
Shutdown switch (see Section 9-9).
9 Fuel Gauge
Use gauge to check fuel level.
To check fuel level when engine is not run-
ning, turn Engine Control switch to Run/Idle
position and press Magnetic Shutdown
switch.
10 Battery Voltmeter (Optional)
Use gauge to check battery voltage and moni-
tor the engine charging system. The meter
should read about 14 volts dc when the en-
gine is running, and about 12 volts dc when
the engine is stopped.
11 Engine Coolant Temperature Gauge
(Optional)
Normal temperature is 180 - 203° F (82 - 95°
C). When equipped with gauge option, engine
stops if temperature exceeds 220° F (104° C).
12 Engine Oil Pressure Gauge (Optional)
Normal pressure is 30 − 60 psi (207 − 414
kPa). When equipped with gauge option, en-
gine stops if pressure is below 10 psi (69
kPa).
Weld Controls
13 Process/Contactor Switch
See Section 7-3 for Process/Contactor
switch information.
14 Ampere Range Switch
Y Do not switch under load.
Use switch to select weld amperage range.
Use the lowest four ranges for Stick and TIG
welding. Read the upper set of numbers at
each range for Stick welding and the lower set
at each range for TIG welding.
Use the highest range for MIG welding and for
cutting and gouging (CAC-A).
For most welding applications, use lowest
amperage range possible to help prevent arc
outages.
15 Voltage/Amperage Adjust Control
With Process/Contactor switch in any Stick or
TIG setting, use control to adjust amperage
within range selected by Ampere Range
switch. With Process/Contactor switch in any
MIG position, use control to adjust voltage.
With Voltage/Amperage Adjust Switch in Re-
mote position, control limits the remote am-
perage in TIG mode, but has no effect in Stick
and MIG modes.
Weld output would be about 213 A DC with
controls set as shown (50% of 110 to 315 A).
. The numbers around the control are for
reference only and do not represent an
actual percentage value.
16 Voltage/Amperage Adjust Switch And
Remote 14 Receptacle
Use switch to select front panel or remote
voltage/amperage control. For remote con-
trol, place switch in Remote position and con-
nect remote control to Remote 14 receptacle
RC14 (see Sections 5-11 and 7-4).
17 Polarity Switch (Optional)
Y Do not switch under load.
Use Polarity switch to change weld output.
Select either DC Electrode Positive (DCEP)
or DC Electrode Negative (DCEN).
18 Polarity/AC Switch (Optional)
Y Electric shock can kill.
Y Do not use AC output in damp areas,
if movement is confined, or if there is
a danger of falling.
Y Use AC output ONLY if required for the
welding process. If AC output is re-
quired, use remote output control if
present on unit.
Y Do not switch under load.
Use Polarity/AC switch to select AC or DC
weld output and DC weld output polarity. For
Direct Current Electrode Negative (DCEN),
turn switch to − (Negative) position. For Direct
Current Electrode Positive (DCEP), turn
switch to + (Positive) position. For weld pro-
cesses that require alternating current (AC),
use AC position.
Weld Meters
. Optional weld meters do not work with
optional Polarity/AC switch in AC
position.
19 DC Voltmeter (Optional)
Voltmeter displays voltage at the weld output
terminals, but not necessarily the welding arc
due to resistance of cable and connections.
20 DC Ammeter (Optional)
Ammeter displays amperage output of the
unit.
