4.3 Mains supply
NOTE!
Mains supply requirements
This equipment complies with IEC 61000-3-12 provided that the short-circuit power is
greater than or equal to S
scmin
at the interface point between the user's supply and
the public system. It is the responsibility of the installer or user of the equipment to
ensure, by consultation with the distribution network operator if necessary, that the
equipment is connected only to a supply with a short-circuit power greater than or
equal to S
scmin
. Refer to the technical data in the TECHNICAL DATA chapter.
The supply voltage should be 230VAC±10% or 120V±10%. Too low supply voltage may
cause poor welding performance. Too high welding supply voltage will cause components to
overheat and possibly fail. Contact the local electric utility for information about the type of
electrical service available, how proper connections should be made, and inspection
required.
The welding power source must be:
• Correctly installed, if necessary, by a qualified electrician.
• Correctly earthed (electrically) in accordance with local regulations.
• Connected to the correct size power point and fuse as table below.
NOTE!
Use the welding power source in accordance with the relevant national regulations.
CAUTION!
Disconnect input power and secure employing ‘Lock-out’ / ‘Tagging’ procedures.
Ensure input power line disconnect switch is locked (lock-out/Tagging) in the ‘Open’
position BEFORE removing input power fuses. Connection/Disconnect should be
carried out by competent persons.
