Controls and Operational Features
1. Power Indicator: After input power is connected and
the power switch is turned on, this lamp will light up
to indicate the machine is ready to weld.
2. Thermal Overload Indicator: This lamp will light up
when the machine is overheated and the output has
been turned off. This can occur if the ambient
temperature is above 40°C or the duty cycle of the
machine has been exceeded. Leave the machine
on to allow the internal components to cool, when
the lamp turns off normal operation is possible.

Thermostatic fan:
controlled by the thermal protection circuit. In this
mode the fan is operating only while cooling
is needed. This feature saves energy and also
minimizes the amount of dirt and other air borne
particles being
Thermostatic fan is switched off by factory
default. If you want to activate it:

Ensure that the input cable must be
disconnected from the main supply and the
machine switched OFF.

Remove the top panel from the machine.

Reconnect X13 according to the diagram
below:

Replace the top panel.
3. Power on/off Switch: Controls the input power to
the machine.

the fan can be additionally
drawn into the machine.
4. Hot Start Control: Hot Start is a temporary increase
in the output current during the start of stick (MMA)
welding that helps ignite the arc quickly and reliably.
The potentiometer is used to set the level of the
increased current.
5. Negative Quick Disconnect:
connector for the welding circuit.
6. Digital Welding Current Meter with memory feature:
Shows present the value of the welding current
during welding; after welding it continues to display
the average welding current.
7. Output Current Control: Potentiometer used to set
the output current (also during welding).

8. Local/Remote Switch: Remote Control Unit can be
used with this machine. It changes control of the
Output Current from the machine Output Control
(point 7) and vice versa.
9. Arc Force Control: It is a function used during stick
(MMA) welding in which the output current is
temporarily increased
connections between the electrode and the weld
puddle that occur during normal welding.
10. Remote Control Connection: If a remote control is
used, it will be connected to the remote connector.
11. Positive Quick
connector for the welding circuit.
12. Mode Switch:
modes of the machine. The CITOROD 4005XT &
6700XT has two welding modes: Stick (MMA) and
Lift TIG (GTAW).
When the mode switch is in the Stick position, the
following welding features are enabled:

Hot Start

Arc Force

Anti-Sticking: This is a function which decreases
the output current of the machine to a low level
when the operator makes an error and sticks the
electrode to the work piece. This decrease in
current allows the operator to remove the
electrode from the electrode holder without
creating large sparks which can damage the
electrode holder.
When the mode switch is in the Lift TIG position, the
stick welding functions are disabled and the
machine is ready for Lift TIG welding. Lift TIG is a
method of starting a TIG weld by first pressing the
TIG torch electrode on the work piece in order to
create a low current short circuit.
electrode is lifted from the work piece to start the
TIG arc.
