5. Protection against overheating
The power source is equipped with a thermal, automatic overload switch. When the temperature of
the welding machine is too high, the protection will disconnect the welding current and the diode
signaling overheating will light (1). After the temperature has dropped, the breaker will be
automatically reset.
