ADDITIONAL SAFETY INSTRUCTIONS

24. If, in an emergency, it must be disconnected,

guard against shock burns, or flash from switch

arcing. Always shut OFF and disconnect all

power to equipment. Power disconnect switch

must be available near the welding power

source.

25. Fully insulated electrode holders should be

used. Do NOT use holders with protruding

screws or with any form of damage.

26. Fully insulated lock-type connectors should be

used to join welding cable.

27. Frequently inspect cables for wear, cracks and

damage. IMMEDIATELY REPLACE those with

excessively worn or damaged insulation to

avoid possibly lethal shock from bared cable.

Cables with damaged areas may be taped to

give resistance equivalent to original cable.

Keep cable dry, free of oil and grease, and

protected from hot metal and sparks.

INSTALLATION

ENVIRONMENT

These units are designed for use in environments

with increased hazard of electric shock.
A. Examples of environments with increased

hazard of electric shock are:

1. In locations in which freedom of movement is

restricted, so that the operator is forced to

perform the work in a cramped (kneeling,

sitting or lying) position with physical contact

with conductive parts.

2. In locations which are fully or partially limited

by conductive elements, and in which there is

a high risk of unavoidable or accidental contact

by the operator.

3. In wet or damp hot locations where humidity

or perspiration considerable reduces the skin

resistance of the human body and the

insulation properties of accessories.

B. Environments with increased hazard of electric

shock do not include places where electrically

conductive parts in the near vicinity of the

operator, which can cause increased hazard,

have been insulated.

LOCATION

This machine can operate in harsh environments.

However, it is important that simple preventative

measures are followed to assure long life and reli-

able operation:

This machine must be located where there is

free circulation of clean air without restrictions

for air movement to and from the air vents. Do

not cover the machine with paper, cloth or rags

when switched on.

Dirt and dust that can be drawn into the

machine should be kept to a minimum.

This machine has a protection rating of IP21S.

Keep it dry and do not place it on wet ground

or in puddles. Do not use in wet or damp

locations. Store indoors.

Locate the machine away from radio controlled

machinery. Normal operation may adversely

affect the operation of nearby radio controlled

machinery, which may result in injury or

equipment damage.

Read the section on electromagnetic compatibility

in this manual.

Do not operate in areas with an ambient

temperature greater than 40°C.

TILTING

Place the machine directly on a secure, level

surface.
Do not place or operate this machine on a surface

with an incline greater than 15° from horizontal.

The machine may topple over if this procedure is

not followed.

VENTILATION

This cutting machine can create powerful cutting

current and has strict cooling requirements that

cannot be met with natural ventilation. Therefore

the built-in fan is very important in enabling the

machine to work stable with effective cooling. The

operator should make sure that the louvers be

uncovered and unblocked. The minimum distance

between the machine and nearby objects should

be 25cm.
