Engine Controls (Items 1 Through to 9)
1. RUN STOP SWITCH
Toggling the switch to the RUN position energises the fuel
solenoid, hour meter and rotor flashing circuit.
Note:
Do not leave switch in Run Position when engine is not
running. In the Run position the battery will be discharged.
2. START PUSHBUTTON
Energises the starter motor to crank the engine. With the engine
“Run / Stop” switch in the “Run” position, push and hold the Start
button to crank the engine; release as the engine starts. Do not
press while engine is running as this can cause damage to the
ring gear and/or starter motor.
3. BATTERY CHARGING LIGHT
The yellow engine alternator light is off when battery charging
system is functioning normally. If light turns on, the alternator or
the voltage regulator may not be operating correctly. The light will
remain on when the engine is stopped and the run/stop switch is
in the run position.
4. FUEL LEVEL GAUGE
Displays the level of diesel fuel in the fuel tank. The operator must
watch the fuel level closely to prevent running out of fuel and
possibly having to bleed the system.
5. ENGINE PROTECTION
The yellow engine protection light remains off with proper oil
temperatures. If the light turns on, the engine protection system
will stop the engine. Check for proper oil level and add oil if
necessary. Check for loose or disconnected leads at the oil
temperature sender located on the engine. Check for broken fan
belt. The light will remain on when the engine has been shut down
due to oil temperature condition.
6. HOUR METER
The hour meter displays the total time that the engine has been
running. This meter is a useful indicator for scheduling preventive
maintenance.
7. CIRCUIT BREAKERS
These circuit breakers provide separate overload current
protection for each 230/240V receptacle, rotor circuit and battery
circuit overload protection.
8. 230/240 VAC RECEPTACLE
The 230/240 VAC receptacle provides up to 15 amp rating
and is IP44 rated. Refer to the AUXILIARY POWER
RECEPTACLE section in the installation chapter for further
information about the receptacle. Also refer to the AUXILIARY
POWER OPERATION section later in this chapter.
9. FINE OUTPUT CONTROL
The ‘Fine Output Control” provides for the final adjustment to the
welding current selection. 230V power zone indicates where
welding output on simultaneous auxiliary power are available.
10. WELD OUTPUT TER AND -
These 1/2" - 13 UNC studs with hand nuts provide welding
connection points for the electrode and work cables. For positive
polarity welding the electrode cable connects to the “+” terminal
and the work cable connects to this “-” terminal. For negative
polarity welding the work cable connects to the “+” terminal and
the electrode cable connects to this “-” terminal.
The “-” terminals are High Inductance for Stick/TIG welding and
Low Inductance for FCAW/Arc Air gouging.
The hand nuts are designed to be tightened by hand, without the
need for a spanner.
11. EARTH STUD
Provides a connection point for connecting the machine case to
earth. Refer to “MACHINE EARTHING” in the Installation chapter
for proper machine earthing information.
12. VOLT/AMP METERS (optional)
Optional analog volt and amp meter kit available for easy
installation into front panel. (Pat No K32019-1)
13. COURSE OUTPUT CONTROL
Firstly set the “Coarse Output Control” to the lowest setting to
obtain the required output current and then adjust the ‘Fine
Output Control’ between minimum and maximum to obtain the
final setting for the output current.
Note: Do not switch this switch while welding
The ‘Output Selector’ provides 8 course current positions:
• OFF
• Minimum - 75
• 40 - 120
• 45 - 180
• 50 - 300
• 55 - 400
• 60 - 550
• 70 - Maximum
Welding Power Source Safety
Welding power sources generally have an Open Circuit Voltage
(i.e. the voltage at the welding output terminals whilst not welding)
in the ranges of 35-115VDC. Welding machines for stick welding
(MMAW) and similar constant current (CC mode) processes,
supply a higher open circuit voltage between the electrode and
the work when the welding machine is switched on and ready to
commence welding. These welding machines have a drooping
characteristic, with the open circuit voltage higher (typically
60-90V) than when the arc is established and welding current is
drawn (20-35V).
Consequently, the greatest danger occurs when handling the
electrodes and the electrode holder between welding operations,
such as when changing electrodes.
The voltage at the output terminal maybe up
to 88V DC.
