MODE SELECTION ON THE WELDING MACHINE
On the machine, press the button several times until the LED light switches on below the symbol .
Both display show and the knobs are inactive, all controls are now operated from the wire feeder’s interface (FIG-2).
WELDING PARAMETERS SETTINGS
1. Setting the welding voltage :
Adjust the welding voltage using the main knob depending on the work to be carried out. The voltage setpoint is indicated on the left side
display.
2. Setting the wire speed :
Adjust the wire speed using the right knob depending on the work to be carried out. The speed setpoint is indicated on the right side display.
3. Setting the inductance :
While pressing the button , turn the knob , the index shows a value from -9 à +9. The lower the inductance level, the harder and more
guiding the arc. The higher the inductance and the softer the arc with little splatter.
ACCESS TO ADVANCED SETTINGS
Refer to the chapter « menu access » for more details regarding welding parameters.

: these settings are only available in Spot / Delay mode.
(2)
: the Hotstart settings are only available in Spot / Delay mode.
(3)
: these settings are only visible if H.S. is set to « On ».
(4)
: the CraterFiller settings are only available in Spot / Delay mode.
(5)
: these settings are only visible if C.F. is set to « On ».
DISPLAY CURRENT/VOLTAGE DURING WELDING
During welding, the machine measures and displays the welding current and voltage. After the weld, the average current and voltage values are
displayed during 30 seconds, as soon as a knob or a button is pressed, the welding parameters are displayed.
Depending on the operation (short-circuit, globular or spray-arc), the average voltage can slightly differ from the setpoint voltage.
SAVE AND LOAD WELDING SETTINGSS
The current settings are automatically saved and loaded at start up.
On top of the current settings, it is also possible to save and load settings per each mode.
There are 50 memory slots
The saved settings include :
- voltage, wire speed and inductance,
- advanced settings.
- 2T / 4T / SPOT DELAY mode
