ESAB FABRICATOR 181i
SAFETY AND INSTALLATION 3-4 Manual 0-5449
3.05 Ventilation
!
WARNING
Since the inhalation of welding fumes can be harmful, ensure that the welding area is effectively
ventilated.
3.06 Electricity Supply Voltage
!
WARNING
The Electricity Supply voltage should be within 208-265V AC. Too low a voltage may cause poor
welding performance in STICK mode. Too high a supply voltage will cause components to over-
heat and possibly fail.
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 per the Specifications on page 3-2.
!
WARNING
The Fabricator 181i must be electrically connected by a qualified electrical trades-person. Damage to the
PCA (Power Control Assembly) could occur if 265 VAC or higher is applied to the Primary Power Cable.
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 con-
sist 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 supply. The input voltage must match one of the electri-
cal input voltages shown on the input data label on the unit nameplate. Contact the local electric utility for information about the type
of electrical service available, how proper connections should be made, and inspection required. The line disconnect switch provides a
safe and convenient means to completely remove all electrical power from the welding power source whenever necessary to inspect or
service the unit.
Do not
connect an input (WHITE or BLACK) conductor to the ground terminal.
Do not
connect the ground (GREEN) conductor to an input line terminal.
• 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 3-2. Refer to Table 3-2.
WARNING
An electric shock or fire hazard is probable if the following t electrical service guide recommendations are
not followed. These recommendations are for a dedicated branch circuit sized for the rated output and duty
cycle of the welding Power Source.
