Controls And Operational Features; Front Panel Controls - Lincoln Electric TOMAHAWK 1025 Manual De Instrucciones

WARNING
Always turn OFF the machine when working on the
torch.
WARNING
Do not remove the work clamp during cutting, plasma
cutting generates high voltages that can kill.
WARNING
Open Circuit Voltage U
information refer to the Technical Specification section.
Torch Connector:
Connect here the cutting
torch. The torch
connection to the power
source is very easily
performed through a quick-
connector carrying the
torch trigger circuit, the gas
line and the torch power
cable.
Torch Connector Polarization Key:
This Plasma Cutting Machine shall be used with its
specific torch. The polarized torch connector avoid the
risk to use the machine with a not proper torch model.
The position of the polarized key is shown in the table
below.

Controls and Operational Features

Machine Auto-Test:
When the machine is turned ON, an auto-test is
executed; during this test all of the LEDs of the
Commands Front Panel lights up. If one or some LED
remains OFF, contact the nearest technical service
center or Lincoln Electric and report the LED Status
found on the machine Front Panel.

Front Panel Controls

Output Current Knob:
Potentiometer used to set the output
current used during cutting. Refer to the
Technical Specification section for more
information about the machine rated
current range.
Gas Purge:
The Output Current Knob completely
rotated counterclockwise enables the gas
purge function.

Positive Quick Disconnect:
Positive output connector
for the cutting circuit. As
far the ground connection,
this is to be connected to
the work piece and to a
"DINSE" connector on the
front of the power source.

Power ON/OFF LED:
It lights up when the machine is ON.
Blinking LED: Mains out of range
condition. The machine is disabled:
when the mains returns in the correct
range, the machine restart automatically.
Note: The Fan could be automatically
switched OFF if the error condition
persist for more than 2seconds.
Output LED:
The cutting torch is energized.
Blinking LED: Internal auxiliary
undervoltage condition. The machine
needs to be turned OFF then ON again to
restart.
Thermal LED:
The machine is overheated and the
output has been disabled. This usually
occurs when the duty cycle of the
machine has been exceeded. Leave the
machine ON to allow the internal
components to cool. When the thermal
LED turns off, normal operation is again
possible.
Low gas pressure condition LED:
With this LED ON the machine stops
cutting or gouging operations. The
machine restart automatically when a
correct gas pressure is detected.
To check / adjust the primary gas
pressure (see recommended values in
the Tecnical Specifications of this
manual):
•
When this LED lights up, for 10
seconds the machines goes
automatically in Purge mode.
•
During Purge time check and adjust
the gas pressure through the
manometer and primary gas
pressure regulator knob.
•
If necessary, check and adjust also
the inlet gas pressure through the
commands of the inlet primary gas.
PIP LED:
Part in place condition: the torch retaining
cap (or the torch connector) is not
properly screwed on the torch head (or in
the machine torch connector).
To restore the machine:
•
Screw firmly the torch retaining cap
(or the torch connector).
•
After the torch is restored, the
machine cannot restart for about 5
seconds. During this time the PIP
LED blinks.
(Note: When the LED is blinking, if
another PIP error occours or if the
Torch Trigger pushbutton is pressed
the machine returns to the error
condition: PIP LED returns steady
ON and the restoring procedure
begins again).
•
When the PIP LED turns OFF the
machine is ready to operate.
