General safety recommendations
Safety instructions
These instructions contain important information which
either supplements or supersedes other instruction re-
lating to this product� Read these instructions carefully
before commencing operation�
Furthermore, the installation and use of the device
must follow the instructions given in the international
standard: IEC 60974-9 Arc welding equipment Part 9�
Installation and use
Use of personal protective equipment:
• The arc and its reflecting radiation damage unpro-
tected eyes� Shield your eyes and face appropriately
before you start welding or observe welding� Also
note the different requirements for the darkness of the
screen in the mask as the welding current changes�
• The arc radiation and spatters burn unprotected
skin� Always wear protective gloves, clothing and foot-
wear when welding�
• Always wear hearing protection if the ambient noise
level exceeds the allowable limit�
General operating safety
• Exercise caution when handling parts heated in
welding� For example, the tip of the welding torch, the
end of the welding rod and the work piece will heat to
a burning temperature�
• Never carry the device or suspend it by the carrying
strap during welding�
• Do not expose the machine to high temperatures, as
this may cause damage to the machine�
• Keep the torch cable and earthling cable as close
to each other as possible throughout their length�
Straighten any loops in the cables� This minimizes
your exposure to harmful magnetic fields, which may
interfere with a pacemaker, for example�
• Do not wrap the cables around the body�
• In environments classified as dangerous, only use S-
marked welding devices with a safe idle voltage level�
These work environments include, for example, humid,
hot or small spaces where the user may be directly ex-
posed to the surrounding conductive materials�
• Do not use arc welding equipment for pipe thawing�
Spatter and fire safety
• Welding is always classified as hot work, so pay at-
tention to fire safety regulations during welding and
after it�
• Remember that fire can break out from sparks even
several hours after the welding work is completed�
• Protect the environment from welding spatter� Re-
move flammable materials, such as flammable fluids,
from the welding vicinity and supply the welding site
with adequate firefighting equipment.
• In special welding jobs, be prepared for hazards
such as fire or explosion when welding container-type
work pieces�
• Never direct the spark spray or cutting spray of a
grinder toward the welding machine or flammable ma-
terials�
• Beware of hot objects or spatter falling on the ma-
chine when working above the machine�
• Welding in flammable or explosive sites is abso-
lutely forbidden�
General electric safety
• Only connect the welding machine to an earthed
electric network�
• Note the recommended mains fuse size�
• Do not take the welding machine inside a container,
vehicle or similar work piece�
• Do not place the welding machine on a wet surface
and do not work on a wet surface�
• Do not allow the mains cable to be directly exposed
to water�
• Ensure cables or welding torches are not squashed
by heavy objects and that they are not exposed to
sharp edges or a hot work piece�
• Make sure that faulty and damaged welding torches
are changed immediately as they can be lethal and
may cause electrocution or fire.
• Remember that the cable, plugs and other electric
devices may be installed or replaced only by an electri-
cal contractor or engineer authorized to perform such
operations�
• Turn off the welding machine when it is not in use�
• In the case of abnormal behavior of the equipment,
such as smoke coming from the machine during nor-
mal use, take the machine to a CROWN service repre-
sentative for inspection�
Welding power circuit
• Insulate yourself from the welding circuit by using
dry and undamaged protective clothing�
• Never touch the work piece and welding rod, weld-
ing wire, welding electrode or contact tip at the same
time�
• Do not put the welding torch or ground cable on the
welding machine or other electric equipment�
• Turn off the machine from the main switch always
before you need to touch any components of the elec-
tric circuit, for example when replacing the electrode or
contact tip or moving the earth return clamp�
Welding fumes
• Ensure proper ventilation and avoid inhaling the
fumes�
• Ensure sufficient supply of fresh air, particularly in
closed spaces� You can also ensure the supply of clean
and sufficient breathing air by using a fresh-air mask.
• Take extra precautions when working on metals or
surface-treated materials containing lead, cadmium,
zinc, mercury or beryllium�
Transportation, lifting and suspension
• Pay attention to correct working position when lifting
a heavy device risk of injury to the back�
• Never pull or lift the machine by the welding torch
or other cables� Always use the lift points or handles
designed for that purpose�
• Only use a transport unit designed for the equip-
ment�
• Try to transport the machine in an upright position,
if possible�
• Never lift a gas cylinder and the welding machine at
the same time� There are separate provisions later for
gas cylinder transportation�
• Never use a welding machine when suspended un-
less the suspension device has been designed and ap-
proved for that particular purpose�
