OPERATIONAL FEATURES AND
CONTROLS
FRONT PANEL (SEE FIGURE B.1)
1. GAS SELECTION
®
OPTIMARC CV/CC500 is designed for CO2 and
Ar/CO2.
2. WELDING MODE SELECTION
®
OPTIMARC CV/CC500 includes 5 following modes:

OPTIONAL.
A default procedure is for self-shielded flux
cored wire arc welding.

FCAW-GS.
It is for gas shielded flux cored wire arc welding.
Setting up the machine, please see the Figure
A.3

GMAW.
It is for gas shielded solid wire arc welding.

GTAW.
It is for TIG mode. OPTIMARC
must apply "touch start" for arc start.

SMAW.
It is for stick mode.
3. WIRE DIAMETER SELECTION
®
CV/CC500 is designed for Φ1.0, Φ1.2
OPTIMARC
and Φ 1.6 wires.
4. ON/OFF POWER SWITCH
Switch up to power on; Switch down to power off.
5. CONTROL SWITCH

LOCAL
When switch to local，the output current or output
voltage can be setted by output control knob (See
item 15).

FEEDER
When switch to feeder，the welding current and
voltage can be setted by the feeder knob in GMAW
mode (See item 19).

REMOTE
When switch to remote，the welding current or
voltage can be setted by a remote control box,
choose the right connector according to the weld
mode (See item 18).
6. THERMAL INDICATOR
This status light illuminates when the power source has
been driven into thermal overload. The indicator light
also momentarily turns on during start up.
7. 2-STEP AND 4-STEP SELECTION
This toggle switch enables the selection of 2-STEP or
4-STEP operation mode without or with crater function.
2-STEP mode - no crater output after user release the
trigger. 4-STEP mode – crater function initiates when
uses "Clicks" trigger again after releasing it. Please
see FIGURE B.3 and B.4 to know the more details of
time sequence of OPTIMARC

8. DIGITAL INDICATION VOLTAGE METER
This meter displays the preset voltage before a weld
and the actual voltage during a weld . The actual
voltage is displayed for 5 seconds after a weld ends.
During this time the display flash.
9. SYNERGIC
This status light illuminates when the power source is
set for synergic operation. Synergic operation is
controlled by DIP switch 5 on the control board. See
the DIP switch section for additional information.
10. DIGITAL INDICATION CURRENT METER
This meter displays the preset current before a weld
and theactual welding current during a weld. The
actual current is displayed for 5 seconds after a weld
ends. During this time the display falsh.
11. CRATER VOLTAGE
This knob sets the value of output voltage during the
crater time.
12. CRATER CURRENT
This knob sets the value of output current (wire
feeding speed) during the crater time.
13. HOT START
This knob can be used for setting the additional output
value at the start of weld in all of modes.
14. ARC CONTROL
This knob control the arc output characteristic. When
it is turned clockwise, the arc is crisper. When it
turned counter clockwise,the arc is softer.
15. LOCAL OUTPUT CONTROL
When item 9 is set to "LOCAL", The output voltage
( CV mode ) or output current ( CC mode ) will be
controlled by this knob.
In TIG mode, it will control the maximum output
current.
In stick mode, it will limited the output current range.
16. NEGATIVE OUTPUT STUD
17. POSITIVE OUTPUT STUD
18. 6-PIN AMPHENOL CONNECTOR
Please see the FIGURE A.7 for the details of the
connection. Recommend the standard remote
controller for GTAW mode is K870 ( Foot amptrol );
and standard remote controller for SMAW is K857
( Pot control ).
19. 6-PIN LWF WIRE FEEDER CONNECTOR
Please see the FIGURE A.6 for the details of the
connection.
20. STATUS INDICATOR
The status light will be green for normal operation;
while the status light will flash in red with a serial of
error digital codes as power source gets in some
trouble. The status light will always have
synchronization with the LED3 on switchboard inside
machine.
