ELECTRICALLY POWERED EQUIPMENT:
Turn off input power using the switch at the fuse
box before working on the equipment. Electrical connections should be performed
adequate to the obligated rules.
GROUNDING:
For your safety and trouble-free operation, electrical supply cables should
be connected to a proper grounded receptacle.
ELECTRIC and MAGNETIC FIELDS MAY BE DANGEROUS TO HUMAN HEALTH:
Electric that flows through conducters,
produces electromagnetic
field. This
electromagnetic field can be effective on devices like pacemakers. Users who have a
pacemaker must refer to a physiotherapist before operating the machine.
PLASMA
ARC
MAY
BURN
: Use proper mask, filter and protective glassas to protect your
eyes from sparks and the rays of the plasma cutting arc when performing cutting operation or
observing the operation. Skin should be protected by clothing made from flame resistance
material
.
Protect
other
nearby
personnel
with
suitable
,
non
-
flammable
screening
and
/
or
warn
them not to watch plasma cutting arc nor expose themselves to the arc rays or to hot spatter or
metal
.
When eyes are exposed to UV rays even for a short time, also called as “Getting Welder
'
s
Flash
”,
it
may
cause
burns
in
your
eyes
.
Getting
Welder
'
s
Flash
may
not
be
noticed
after
hours
of exposing, but it is too irritating as well as may cause transient blindness. Normally getting
operato
r
'
s flash is a temporary situation, but exposing eyes to UV rays for a long time and
frequently may cause permanent damage on eyes. As a protection measure besides not to
watch arc rays, also using
cutti
ng goggles having proper filter is necessary. Following table
may be useful for choosing proper filter for plasma cutting applications.
