Engine Controls - Lincoln Electric VANTAGE 400 CE Manual De Instrucciones

a remote control is connected to the 6-pin
Connector, the auto-sensing circuit
automatically switches the OUTPUT control
from control at the welder to remote control.
•
When in TOUCH START TIG mode and when a
Amptrol is connected to the 6-Pin Connector,
the OUTPUT dial is used to set the maximum
current range of the CURRENT CONTROL of
the Amptrol.
9. Weld Terminals Control Switch: In the WELD
TERMINALS ON position, the output is electrically
hot all the time. In the REMOTELY CONTROLLED
position, the output is controlled by a wire feeder or
trigger device, and is electrically off until a trigger
switch is depressed.
10. Wire Feeder Voltmeter Switch: Matches the polarity
of the wire feeder voltmeter to the polarity of the
electrode.
11. VRD (Voltage Reduction Device) Indicator Lights:
The VRD feature provides additional safety in the
CC-Stick mode especially in an environment with a
higher risk of electric shock such as wet areas and
hot humid sweaty conditions. The VRD reduces the
OCV (Open Circuit Voltage) at the welding output
terminals while not welding to less than 32V DC
when the resistance of the output circuit is above
200 ohms.
The machine is shipped with the VRD switch in the
"Off" position. To turn it "On" or "Off":
• Turn the engine "Off".
•
Disconnect the negative battery cable.
•
Lower the control panel by removing 4 front
panel screws (see figure below point "A").
•
Place the VRD switch in the "On or "Off"
position (see figure below point "B").
The red light indicates OCV(Open Circuit Voltage) is
equal to or greater than 32V and a green light when
lit indicates OCV is less than 32V. 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.
Note: Due to the requirement of the resistance in
the circuit to be low for a VRD to operate, a good
metal-to-metal contact must be made between the
metal core of the electrode and the job. A poor
connection anywhere in the welding output circuit
may limit the operation of the VRD. This includes a
good connection of the work clamp to the job. The
work clamp should be connected as close as
practical to where the welding will be performed.
For New Electrodes:
•
E6010 - Touch, Lift to Start the Arc.
•
E7018, E7024 - Touch, Rock Back and Forth in
Joint, Lift.
Once the arc is started, normal welding technique
for the application is then used.
For Re-Striking Electrodes:
Some electrodes form a cone at the end of the
electrode after the welding arc has been broken,
particularly iron powder and low hydrogen
electrodes. This cone will need to be broken off in
order to have the metal core of the electrode make
contact.

Engine Controls

12. Run/Stop Switch: RUN position energises
the engine prior to starting. STOP position
stops the engine. The oil pressure interlock
switch prevents battery drain if the switch is left in
the RUN position and the engine is not operating.
13. Glow Plug Push Button: When pushed
activates the glow plugs. Glow plug should
not be activated for more than 20 seconds
continuously.
14. Start Push Button
15. Idler Switch:
Has two positions:
•
In the HIGH position, the engine runs
continuously at the high idle speed.
•
In the AUTO position, the idler operates as
follows:
•
When switched from HIGH to AUTO or
after starting the engine, the engine will
operate at full speed for approximately 12
seconds and then go to low idle speed.
•
When the electrode touches the work or
power is drawn for lights or tools
(approximately 100 Watts minimum), the
