6. Wear fi rm, insulated footwear. Your shoes should
also protect you in wet conditions. Open- toed
footwear is not suitable since falling droplets of
glowing metal will cause burns.
7. Wear suitable clothing, do not wear synthetic
clothes.
8. Do not look into the arc with unprotected eyes,
use only a welding safety shield with the proper
safety glass in compliance with DIN standards. In
addition to light and heat, which may cause daz-
zling and burns, the arc also gives off UV radia-
tion. Without proper protection, this invisible ultra-
violet radiation causes very painful conjunctivitis,
which will only be noticeable several hours later.
In addition, UV radiation will cause sunburn-type
symptoms on unprotected parts of the body.
9. Personnel or assistants in the vicinity of the arc
must also be notifi ed of the dangers and provided
with the required protection; if necessary install
safety walls.
10. Ensure adequate ventilation for welding, par-
ticularly in small rooms since the process causes
smoke and harmful gases.
11. Do not carry out any welding work on tanks that
have been used to store gases, fuels, mineral oil
or the like, even if they have been empty for a
lengthy period of time, since any residue will result
in a danger of explosion.
12. Special regulations apply in areas where there is
a potential risk of fi re and/or explosion.
13. Welds that are exposed to large stresses and
must comply with safety requirements may only
be completed by specially trained and approved
welders. Examples of such welds include pres-
sure vessels, rails, trailer hitches, etc.
14. Only use a power source (with earthing contact)
that is protected with a slow-blow fuse, a slow-
triggering circuit breaker and a residual current
device.
The fuses must comply with the relevant
regulations (VDE 0100). To comply with these
regulations, only fuses or circuit breakers suitable
for the cross-section of the cables may be used.
The use of too high a fuse may result in the cable
burning and fi re damage to the building.
This appliance is not designed for commercial use.
CONSTRICTED AND WET AREAS
When working in constricted, wet or hot areas, use
insulating supports and intermediate layers as well as
slip-on gloves made of leather or other non-conduc-
tive materials to insulate your body against the fl oor,
walls, conductive parts of the machine and the like.
If you use small welding transformers for welding in
places with an increase electrical risk, for example in
constricted areas with conductive walls, (tanks, pipes,
etc.), in wet areas (which make work clothes wet) and
in hot areas (perspiration on work clothes), the output
voltage of the welding set when idling must not ex-
ceed 42 V (effective value). Therefore, the appliance
may not be used for these purposes because its out-
put voltage is higher than this.
Safety clothing
1. While working, the welder must protect his entire
body from radiation and burns by wearing suitable
clothing and a face guard.
2. Slip-on gloves made of a suitable material (leather)
must be worn on both hands. They must be in per-
fect condition.
3. Suitable aprons must be worn to protect clothing
from sparks and burns. A safety suit and, if neces-
sary, head protection must be worn if required by the
type of work in question, e.g. overhead welding.
PROTECTION FROM RADIATION AND
BURNS
1. Provide information about the risk to eyes at the
working site in the form of a poster with the wording
«Caution - do not look at the fl ames». Workplaces
are to be screened off wherever possible so
that personnel in the vicinity are protected.
Unauthorized persons are to be kept away from
the welding work.
2. The walls in the immediate vicinity of stationary
workplaces should not have a light color or a
sheen. Windows up to head height are to be
protected against radiation passing through them
or refl ecting off them, for example by coating them
with a suitable paint.
