N- GENERAL ON/OFF SWITCH. VOLTAGE CHANGE.
With this switch we can start up the power source. In position 0, the equipment is disconnected. It is started
up by turning the control towards the relative supply voltage position. (see section 2.1.)
P- DIGITAL VOLTMETER.
It measures the voltage of the welding circuit.
Q- DIGITAL AMMETER.
It measures the intensity of the welding circuit.
R- ON-OFF INDICATOR.
Equipment ON/OFF indicator light. It must stay ON when activating control N. If not, fuse T could have
"BLOWN", fault in the mains, etc.
S- THERMAL OVERHEATING INDICATOR.
Power source thermal disconnection indicator light, which comes on when the power rectifier overheats.
With this light on, the power source is not operative.
T- FUSE-HOLDER.
Control circuit protection fuse system.
U- WORKING MODE SELECTOR SWITCH IN MULTIPROCESSING EQUIPMENT.
With this, the working mode can be selected in multiprocessing equipment.
MIG: MIG/MAG welding working mode.
MMA: (Rutile and basic) electrode welding working mode. Hot start.
TIG: TIG welding working mode with lift arc (LIFT-ARC).
V- ADJUSTMENT OF MMA/TIG WELDING CURRENT IN MULTIPROCESSING EQUIPMENT.
Welding mode current adjustment potentiometer in MMA/TIG working mode.
IN THIS TYPE OF ELECTRONIC EQUIPMENT THE WELDING VOLTAGE
IS ADJUSTED REMOTELY FROM THE ACTUAL WIRE-FEED UNIT.
