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
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
TECHNICAL DATA chapter.
The supply voltage should be 230 V AC ± 10% or 120 V ± 10%. Too low welding 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.
SHUT DOWN welding power source; disconnect input power employing lockout/tagging
procedures. Lock-out/tagging procedures consist of padlocking line disconnect switch in
open position, removing fuses from fuse box, or shutting OFF and red-tagging circuit breaker
or other disconnecting device.
