Main 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 230 V AC ±10% or 120 V AC ±10%. Too low supply voltage may cause poor welding perfor-
mance. Too high 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 tables 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. Connecting/disconnecting should be carried out
by competent persons.
