2.4 THERMAL PROTECTION
This inverter is protected by a thermostat. When the
thermostat is tripped, the machine stops delivering
current but the fan continues to run. The yellow led
(19) lights to indicate when it is tripped. Do no shut off
the welding machine until the led has gone off.
2.5 MOTOR-DRIVEN GENERATORS
These must have a power equal to or greater than 20
kVA and must not deliver a voltage greater than 440 V.
2.6 PROTECTION AGAINST SHORT-CIRCUITS
(ANTI-STICK)
If a short-circuit occurs lasting more than two seconds
when welding with covered electrodes, the current is
reduced to harmless levels.
3. INSTALLATION
This must be carried out by skilled personnel. All
connections must be carried out according to current
regulations, and in full observance of safety laws
(CEI reglement 26-10 – CENELEC HD 427).
