DIAZED xxA gG safety fuses are recommended. When using automatic circuit-breakers, the "C" trig-
ger characteristic must be used!
[3]
This welding equipment does not comply with IEC 61000-3-12. When connecting a welding machine
to a public low-voltage supply system, the manufacturer or operator has to consult the electricity utili-
ties to make sure the welding machine may be connected.
