Potential Hazards; Protective Clothing - Gude MIG 155/6 W Originalbetriebsanleitung

Gas bottles must always be safely fixed in a vertical
position on a wall support or on a specially manufac-
tured gas bottle cart.
The bottle with shielding gas and the fixed adjust-
ment gas current equipment must not be moved. The
gas bottle valve must be closed during transport.
Close the gas bottle valve after use.

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.
Contact with the hose bundle nozzle and the material
being processed may cause burns.
Do not look into the arc without eye protection;
only use welding protective shield with the proper
protective glass pursuant to DIN. The arc also emits
UV radiation, in addition to light and heat radiation,
which may cause glare and/or burns. The invisible
ultraviolet radiation causes very painful conjunctivitis,
which is only noticeable a few hours later, if sufficient
protection is not worn. In addition, the UV radiation
causes damaging sunburn to areas of the body which
are not protected.
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.
Welded joints which are subject to great strain and
must always meet the safety requirements and may
only be welded by welders who have received special
training and obtained the relevant qualifications.
Examples include: Pressure vessels, sliding rails,
hitches etc.
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 working in small or hot rooms, insulating bases
and interim layers, as well as gauntlets made from
leather or other non-conductive materials, are to be
used to insulate the body against the floor, walls,
conductive parts of the device and similar.
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 welding device
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.

Protective clothing

Caution! Risk of accident due to spraying
sparks
The spraying welding sparks may lead to painful
burn injuries.
Therefore, always observe the following instruc-
tions:
• Always wear a leather apron.
• Use leather gloves.
• Wear suitable head protection when welding
overhead.
• Ensure that your trouser legs cover the tops of
your shoes.
• Wear sturdy, insulating footwear.
