Mains connection

The welding unit is fitted with a protective contact plug. The unit is
operated with fuses or circuit breakers with a rated current of 16A. When
the unit is switched ON, the main switch at the back of the unit is lit up.
If the BOOSTER.PRO is switched on and off frequently (in quick
succession), the unit may be switched to the protective mode. In this
mode, the unit cannot be started and the green lamp is switched on and
off. In this case, switch the unit off and wait for approx. 2 minutes. The
unit can then be restarted.
