Table 3-1: Input Power Source Leads for Fabricator 252i
WARNING
ELECTRIC SHOCK can kill; SIGNIFICANT DC VOLTAGE is present after removal of input power. DO NOT
TOUCH live electrical parts.
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.
Electrical Input Requirements
Operate the welding power source from a single-phase 50/60 Hz, AC power source. 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, fuse and primary supply lead based on Table 3-1.
WARNING
Any electrical work must be carried out by a qualified Electrical Tradesperson.
3.05 Electromagnetic Compatibility
!
WARNING
Extra precautions for Electromagnetic Compatibility may be required when this Welding Power Source is
used in a domestic situation.
A. Installation and Use - Users Responsibility
The user is responsible for installing and using the welding equipment according to the manufacturer’s instructions.
If electromagnetic disturbances are detected then it shall be the responsibility of the user of the welding equipment to
resolve the situation with the technical assistance of the manufacturer. In some cases this remedial action may be as
simple as earthing the welding circuit, see NOTE below. In other cases it could involve constructing an electromagnetic
screen enclosing the Welding Power Source and the work, complete with associated input filters. In all cases,
electromagnetic disturbances shall be reduced to the point where they are no longer Troublesome.
NOTE
The welding circuit may or may not be earthed for safety reasons. Changing the earthing arrangements
should only be authorized by a person who is competent to assess whether the changes will increase the
risk of injury, e.g. by allowing parallel welding current return paths which may damage the earth circuits
of other equipment. Further guidance is given in IEC 60974-13 Arc Welding Equipment - Installation and
use (under preparation).
