• Power supply must never be connected
before the accessories of SK sockets/con-
nectors are properly installed in the device.
• Use dry and undamaged welding gloves
and protective clothing, in order to ensure
proper insulation of the body. It is forbidden
to touch with a bare hand any elements that
are parts of an electric circuit.
• The operator must always make sure that
there is a good electric connection of the
return conductor to the element to be wel-
ded. The connection should be located as
close to the welding zone as possible.
• Maintain the electrode grip, the welding
torch, the chassis ground clamp, welding
cables and the welding machine in proper
technical condition that ensures safe ope-
ration. Damaged cable insulation should be
replaced with new insulation.
• Never dip an electrode into water, to cool
it down.
• When working above the floor level (at
a height), use a safety harness to protect
yourself against falling, in the case of po-
tential electric shock.
• Exercise special caution, when using the
device in small rooms or in rooms with
elevated humidity levels.
1.3 WELDING ARC RADIATION CAN BE
DANGEROUS
The arc generates:
• ultraviolet radiation
(can damage skin and
eyes)
;
• visible light
(can dazzle and impair vision)
;
• infrared
(heat)
radiation
(can damage skin
and eyes)
.
Such radiation can be direct or reflected from
surfaces such as bright metals and light colo-
ured objects.
1.3.1 Eye and face protection
• Use welder’s helmet/shield with an appro-
priate filter to protect you face and eyes
against sparks and welding arc radiation.
• The shield / helmet should provide eye and
face protection against injuries that may
result in welding spatters.
• Welding helmet/shield should be made in
accordance with applicable standards.
1.3.2 Body protection
• The body should be protected by suitab-
le clothing in accordance with applicable
standards.
• Use appropriate protective clothing made
of durable and fire-resistant material, to
ensure proper skin protection.
• The use of neck protection can be necessary
against reflected radiation.
1.3.3 Protection of persons in the vicinity
of an arc
• Protect the remaining personnel present
in the vicinity of welding works against
negative impact of arc radiation and wel-
ding splatters. Warn them about the hazard
resulting from exposure to the welding arc.
In the vicinity of an arc, non-reflective cur-
tains or screens should be used to isolate
persons from the arc radiation. A warning,
e.g. a symbol for eye protection, should
refer to the hazard of arc optical radiation.
Welder’s assistants should also wear
appropriate protective clothing.
