Caution! Fire hazard due to spraying sparks
If the molten or burning metal or slag particles
land on flammable substances, these may ignite
and cause a fire. Therefore, remove all flammable
objects from your workspace before commencing
welding work. Keep a suitable fire extinguisher
to hand.
In this regard, take the following materials into
consideration in particular:
• Paper
• Rags
• Textiles
• Wood and wood fibres
• Rubber
• Plastic
• Petrol
• Oils
• Tar-like substances
• Paints and solvents
No cutting on vessels and pipes if they are open,
containing materials able to explode due to heat or
moisture or able to cause other dangerous reactions.
WARNING! No welding or cutting on closed vessels
and pipes.
Caution! Explosion hazard and fire hazard
due to welding sparks
Both the welding sparks and the welding point
itself, which is heated to high temperatures, may
cause explosions. Therefore, do not use the device
in a potentially explosive environment where
substances such as flammable liquids, gases and
paint mist are present.
Please note:
• When the plasma cutter is in operation, do not
place the burner on the plasma cutter itself nor on
any other electrical device.
• Before finishing your welding work, do not touch
the contact tip itself nor any other metal objects
which touch the contact tip.
• Disconnect the power supply to the device im-
mediately after completing your welding work.
• It is essential to ensure that no cables become
wrapped around your body.
• It is essential to ensure that you are not within
the welding circuit. The burner and earth must
always be on the same side.
The plasma cutter may only be positioned on an even
and flat base. The respective national guidelines and
laws must be observed when carrying out welding
work. This relates, in particular, to the respective
accident prevention provisions.
Welder may only be used on a flat surface and with a
properly secured gas bottle.
In order to prevent damage to the device, it must only
be transported in an upright position.

Potential hazards

Only have work relating to the power supply, e.g.
cables, plugs, sockets etc., carried out by an expert.
This applies, in particular, to the creation of intermedi-
ate cables.
In the event of an accident, disconnect the welding
power source from the mains immediately.
In the event of electrical contact voltage, turn the
device off immediately and have it inspected by an
expert.
Always ensure the electrical contacts are good with
regard to the welding power.
When welding, always wear insulating gloves on both
hands. These protect against electric shock (no-load
voltage of the welding circuit), against harmful
radiation (heat and UV radiation) and against burning
metal and slag spray.
Wear sturdy, insulated footwear; the shoes should
also perform their insulation function when wet.
Low-rise shoes are not suitable since burning metal
droplets which fall downwards cause burns.
Wear suitable clothing and do not wear any synthetic
clothing.
Persons or assistants near to the arc must also be
made aware of the risks and provided with the neces-
sary protective equipment. If necessary, protective
walls are to be constructed.
No welding work may be carried out on containers in
which gases, fuels, mineral oils or similar have been
stored, even if they have been empty for a long time
already, as residues lead to an explosion hazard.
In spaces at risk of fire and explosion, special regula-
tions apply.
Small and hot rooms
Caution! Danger of poisoning / Danger of
asphyxiation
• Significant quantities of smoke and gases are
created during welding work. Ensure that the
smoke and gases can always be removed via a sui-
table opening. However, an oxygen supply must
never be added. This increases the fire hazard.
When using welding transformers for welding work
in situations with an increased electrical risk, e.g.
in small rooms with electrically conductive walls
(boilers, pipes etc.), in hot rooms (sweat-soaked work
clothes), the output voltage of the plasma cutter may
not exceed 48 V~ in idling conditions (effective value).
The device may thus be operated in this case on the
basis of its output voltage in idling conditions.
