• Before connecting the pressure regulator to the gas cylinder, open the cylinder valve briefly to blow
out any dirt.
• Tighten the pressure regulator screw connection on the gas bottle valve to be gas-tight.
• Screw the gas hose connection to the outlet side of the pressure regulator gas-tight.
5.1.11 Mains connection
DANGER
Hazards caused by improper mains connection!
An improper mains connection can cause injuries or damage property!
• The connection (mains plug or cable), the repair or voltage adjustment of the device must
be carried out by a qualified electrician in accordance with the respective local laws or nati-
onal regulations!
• The mains voltage indicated on the rating plate must match the supply voltage.
• Only operate machine using a socket that has correctly fitted protective earth.
• Mains plug, socket and lead must be checked by a qualified electrician on a regular basis!
• When operating the generator, always ensure it is earthed as stipulated in the operating in-
structions. The network created must be suitable for operating machines according to pro-
tection class I.
The welding power source is equipped with an internal clamp device for multiple mains volta-
ges. The currently set mains voltage of the power source must match the supply voltage! The
following steps have to be carried out:
• Visual inspection - comparison between the currently set mains voltage at the power source
and the supply voltage > see 5.1.11.1 chapter
• Adaptation and marking of the mains voltage > see 5.1.11.2 chapter
• Carry out a safety check after intervention in the machine > see 5.1.11.3 chapter!
5.1.11.1 Visual inspection of the set mains voltage
The set mains voltage is marked on the rating plate and the label on the mains connection cable by a
marking. If the marked mains voltage range coincides with the supply voltage, further commissioning may
take place. If the specifications for mains and supply voltage do not match, the mains voltage in the ma-
chine must be reconnected to the supply voltage
> see 5.1.11.2 chapter
.
Removed or not clearly identifiable adhesive labels must be replaced!
