CONTROL PANEL - LEDS (FIG.14)
L1. Setting of current adjustment by remote
control.
L2. Setting of current adjustment from the
front panel.
L3. Setting of visualization of welding volta-
ge on the display.
L4. Setting of visualization of welding current
on the display.
L5. Set welding procedure: LED lights in
TIG, in CV lights simultaneously with L6.
L6. Set welding procedure: LED lights in
MMA, in CV lights simultaneously with
L5.
L7. When on it indicates 2T mode, fl ashing
indicates 2T mode with pulse.
L8. When on it indicates 4T mode, fl ashing
indicates 4T mode with pulse.
L9. Welding parameter adjustment, with
knob 2 (red LED on).
L10. VRD function activated in MMA (red LED
on).
L11. Power voltage present (green LED on)
L12. Thermal protection intervention (yellow
LED on)
Note: With the system in H2O confi gura-
tion, the yellow LED will start fl ashing to
warn of insuffi cient cooling fl uid pressu-
re/fl ow and the welding process will be
interrupted.
WARNING: When the yellow LED is
on, do not cut off power from the cur-
rent generator, as this would interrupt
ventilation to the overheated parts.
When the LED goes off, the welding
process may continue.
