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 maxi-

mum 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.

SAFETY PRECAUTIONS

Read this entire installation section before you

start installation.

ELECTRIC SHOCK can kill.

• Only qualified personnel

should perform this installa-
tion.

• Turn the input power OFF at

the disconnect switch or fuse

box before working on this

equipment. Turn off the input

power to any other equipment

connected to the welding sys-

tem at the disconnect switch

or fuse box before working on

the equipment.

• Do not touch electrically hot parts.

• Always connect the Power Wave® grounding lug

(located inside the reconnect input access door)
to a proper safety (Earth) ground.

-------------------------------------------------------------

SELECT SUITABLE LOCATION

Do not use Power Waves® in outdoor environments. The

Power Wave® power source should not be subjected to

falling water, nor should any parts of it be submerged in

water. Doing so may cause improper operation 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® over combustible

surfaces. Where there is a combustible surface direct-

ly 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 above code 10500 are equipped with F.A.N.

(fan as needed) circuitry. The fan runs whenever the

output is enabled, whether under loaded or open cir-

cuit 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.
