OPERATIONAL FEATURES AND
CONTROLS
FRONT PANEL (SEE FIGURE B.1)
1. ON/OFF POWER SWITCH
Switch up power on; Switch down power off.
2. 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.
3. WELDING MODE SELECTION
IINVERTEC CV/CC500 includes 7 following modes:

FCAW-GS.
It is for gas shielded flux cored wire arc welding.

GMAW STEEL CO2.
It is for gas shielded solid wire arc welding with
100% CO2.

GMAW STEEL Ar/CO2.
It is for gas shielded solid wire arc welding with
mixed gas.

GMAW AL.
It is for gas shielded solid aluminum wire arc
welding.

GMAW STAINLESS.
It is for gas shielded stainless steel wire arc
welding.

SMAW.
It is for stick mode.

GTAW.
It is for TIG mode. INVERTEC CV/CC500 must
apply “touch start” for arc start.
4. DIGITAL INDICATION CURRENT METER
This meter displays the welding current value.
5. DIGITAL INDICATION VOLTAGE METER
This meter displays the welding voltage setting, the
open circuit voltage or actual welding voltage.
INVERTEC CV/CC500 can set output voltage from 10
to 45V.
6. CRATER CURRENT
This knob sets the value of output current (wire feeding
speed) when INVERTEC
®
CV/CC machine works at
crater time.
7. CRATER VOLTAGE
This knob sets the value of output voltage when
INVERTEC
®
CV/CC 500 works at crater time.
8. HOT START
This knob can be used for setting the additional value
of output voltage or current when INVERTEC
®
CV/CC
500 starts arc.
9. ARC CONTROL
This knob control the arc output characteristic. When it
is turned clockwise, the arc is crisper. When it turned
anti-clockwise,the arc is softer.
10. LOCAL OUTPUT CONTROL
When set item 11 into “LOCAL”, The output voltage
( CV mode ) or output current ( CC mode ) will be
preset and adjusted by this knob.
11. CONTROL TYPE SELECTION
INVERTEC CV/CC500 includes 3 types following
control methods:

LOCAL/LN-25PRO.
It is for selecting local control output, please see
item 10. Please take more attention on this
position, INVERTEC CV/CC500 will have OCV
output in CV mode just like there is also OCV
output in SMAW mode.

PWF FEEDER.
It is for welding in CV mode with PWF feeder.

REMOTE/LN-25PRO.
It is for remote control output with a remote
controller connected to item 16.
12. WIRE DIAMETER SELECTION
INVERTEC
®
CV/CC500 is designed for
≤
Φ1.0, Φ1.2-
1.4 and
≥
Φ 1.6 wires.
13. 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 INVERTEC
®
CV/CC 500.
Irregular welding performance will occur if item 13 is
in the incorrect position.
14. NEGATIVE OUTPUT STUD
15. POSITIVE OUTPUT STUD
16. 6-PIN AMPHENOL CONNECTOR
Please see the FIGURE A.8 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 ).
17. 6-PIN PWF WIRE FEEDER CONNECTOR
Please see the FIGURE A.7 for the details of the
connection.
REAR PANEL (PLEASE SEE FIGURE B.2) .
18. INPUT BOX
This insulation box is used to cover the input
connections.
This insulation box must be secure before turning on
the main power supply.
19. INPUT CABLE HOLDING BRACKET
This bracket securely holds the three phase power
