VANTAGE 549
Idler Operational exceptions
When the WELDING TERMINALS switch is in the "Remotely
Controlled" position or the MODE SELECTION switch is in the
ArcLink® position the idler will operate as follows:
• When the triggering device (Amptrol, Arc Start Switch, etc.) is
pressed the engine will accelerate and operate at full speed
provided a welding load is applied within approximately 12
seconds.
• If the triggering device remains pressed but no welding load is
applied within approximately 12 seconds the engine may
return to low idle speed.
• If the triggering device is released or welding ceases the
engine will return to low idle speed after approximately 12
seconds.
2. START SWITCH
Energizes the starter motor to crank the engine. With the engine
"Run / Stop" switch in the "Run" position, push and release the
Start button to start the engine:
• this switch has an amber light (Top of switch) to indicate Glow
light, this engine will automatically apply power to the glow
circuit and indicator light will turn off when glow is
completed. (Engine will crank but will not start until glow
cycle is completed)
• this switch also has a red light (Bottom of switch) it will light
up when there are faults with the engine. (Check engine light
comes on) Field Service Shop will need to connect to
diagnostic plug to read error codes.
3. DASH BOARD GAUGE - The dash board gauge displays
5 gauges:
3a. OIL PRESSURE
The gauge displays the engine oil pressure when the
engine is running.
3b. ENGINE TEMPERATURE
The gauge displays the engine coolant temperature.
3c. 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.
3d. FUEL LEVEL
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.
3e. BATTERY VOLTAGE INDICATOR
Displays the battery voltage and indicates that the
charging system is functioning properly.
4. OUTPUT CONTROL- The OUTPUT dial is used to preset
the output voltage or current as displayed on the digital meters
for the five welding modes.
5. VRD (Voltage Reduction Device) INDICATOR
LIGHTS- On the front panel of the VANTAGE® 549 are two
indicator lights. A red light when lit indicates OCV(Open Circuit
Voltage) is equal to or greater than 30V and a green light when
lit indicates OCV(Open Circuit Voltage) is less than 30V.
The VRD "On/Off" switch inside the control panel must be "On"
for the VRD function to be active and the lights to be enabled.
When the machine is first started with VRD enabled, both lights
will illuminate for 5 seconds.
These lights monitor the OCV(Open Circuit Voltage) and weld
voltage at all times. When not welding the green light will illu-
minate indicating that the VRD has reduced the OCV to less
than 30V. During welding the red light will illuminate whenever
the arc voltage is equal to or greater than 30V. This means that
the red and green light may alternate depending on the weld
voltage. This is normal operation.
If the red light remains illuminated or both VRD lights flash
when not welding, the VRD is not functioning properly. Please
refer to your local field service shop for service.
If the VRD is turned "On" and the lights don't come "On", refer
to the trouble shooting section.
6. DIGITAL OUTPUT METERS- The digital meters allow
the preset arc output voltage (CV-WIRE mode) or preset arc
current (CC-STICK, DOWNHILL PIPE, Arc Gouging and TIG
modes) to be set prior to welding using the OUTPUT control
dial. During welding, the meter display the actual output volt-
age (VOLTS) and current (AMPS). A memory feature holds the
display of both meters on for seven seconds after welding is
stopped. This allows the operator to read the actual current and
voltage just prior to when welding was ceased.
While the display is being held the left-most decimal point in
each display will be flashing. The accuracy of the meters is
+/- 3%.
The meters will display all dashes for preset when ArcLink®
mode is selected.
6a. HIDDEN MENU BUTTON: The hidden setup menu can
be accessed any time the machine is on with the engine run-
ning and not in a welding arc (arc off or OCV). To access,
press the hidden setup menu push button (Figure B.2.) with
the appropriate tool or paper clip, if no tool is readily avail-
able.
NOTE: The menu system will exit automatically if any of the
following conditions are met:
•
If no settings are changed for 10 seconds.
• If the mode selection switch position is changed.
• If the arc status changes to arc or short.
• If the entire setup menu sequence is cycled through.
