Lincoln Electric IM905 POWER WAVE 455M - Manual (Page 12)

LIFTING
Lift the machine by the lift bail only. The lift bail is
designed to lift the power source only. Do not attempt
to lift the Power Wave with accessories attached to it.
STACKING
Power Wave machines can be stacked to a maximum
of 3 high.
The bottom machine must always be placed on a
firm, secure, level surface. There is a danger of
machines toppling over if this precaution is not
taken.
-------------------------------------------------------------
MACHINE GROUNDING
The frame of the welder must be grounded. A ground
terminal marked with the symbol is located inside
the reconnect/input access door for this purpose. See
your local and national electrical codes for proper
grounding methods.
HIGH FREQUENCY PROTECTION
Locate the Power Wave away from radio controlled
machinery.
The normal operation of the Power Wave may
adversely affect the operation of RF controlled
equipment, which may result in bodily injury or
damage to the equipment.

SELECT SUITABLE LOCATION
Do not use Power Wave 455M (CE) in outdoor environ-
ments. The Power Wave 455M (CE) power source should
not be subjected to falling water, nor should any parts of it
be submerged in water. Doing so may cause improper oper-
ation as well as pose a safety hazard. The best practice is to
keep the machine in a dry, sheltered area.
Do not mount the Power Wave 455M (CE) over combustible
surfaces. Where there is a combustible surface directly
under stationary or fixed electrical equipment, that surface
shall be covered with a steel plate at least .060" (1.6mm)
thick, which shall extend not less than 5.90" (150mm)
beyond the equipment on all sides.
Place the welder where clean cooling air can freely circulate
in through the rear louvers and out through the case sides
and bottom. Dirt, dust, or any foreign material that can be
drawn into the welder should be kept at a minimum. Do not
use air filters on the air intake because the air flow will be
restricted. Failure to observe these precautions can result in
excessive operating temperatures and nuisance shutdowns.
Machines are equipped with F.A.N. (fan as needed) circuitry.
The fan runs whenever the output is enabled, whether under
loaded or open circuit conditions. The fan also runs for a
period of time (approximately 5 minutes) after the output is
disabled, to ensure all components are properly cooled.
If desired, the F.A.N. feature can be disabled (causing the
fan to run whenever the power source is on). To disable
F.A.N., connect leads 444 and X3A together at the output of
the solid state fan control relay, located on the back of the
Control PC board enclosure. (See Wiring Diagram)
