These work environments include, for example, humid,
hot or small spaces where the user may be directly
exposed 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
attention 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�
Remove 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
materials�
• Beware of hot objects or spatter falling on the
machine when working above the machine�
• Welding in flammable or explosive sites is absolutely
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
electrical 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 normal
use, take the machine to a DWT service representative
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, welding
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 electric
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 equipment�
• 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
unless the suspension device has been designed and
approved for that particular purpose�
• It is recommended that the wire coil be removed
during lifting or transportation�
Environment
• The welding power source is not suitable for use
in rain or snow, although it can be used and stored
outdoors� Protect the equipment against rain and
strong sunlight�
• Always store the machine in a dry and clean space�
• Protect the machine from sand and dust during use
and in storage�
• The recommended operating temperature range
is -20°C to +40°C. The machine's operation efficiency
decreases and it becomes more prone to damage if
used in temperatures in excess of 40°C�
• Place the machine so that it is not exposed to hot
surfaces, sparks or spatter�
• Make sure the airflow to and from the machine is
unrestricted�
• Always use the machine in an upright position only�
• Arc welding equipment always cause electromag-
netic disturbance� To minimize the harmful effects of
this, use the equipment strictly according to the operat-
ing manual and other recommendations�
Gas cylinders and regulators
• Adhere to the instructions for handling gas cylinders
and regulators�
• Make sure that gas cylinders are used and stored
in properly ventilated spaces� A leaking gas cylinder
may replace the oxygen in the inhaled air, causing
suffocation�
• Before use, make sure that the gas cylinder contains
gas suitable for the intended purpose�
• Always fix the gas cylinder securely in an upright
position, against a cylinder wall rack or purpose-made
cylinder cart�
• Never move a gas cylinder when the flow adjuster
is in place� Put the valve cover in place during
transportation�
• Close the cylinder valve after use�
