MIG/MAG 140/160
x Metals coated with lead, graphite, cadmium,
zinc, mercury or beryllium, or containing any of
these materials, can generate much smoke dur
-
ing welding.
x Welding releases ozone, which is a type of oxy-
gen that can lead to irritation or disorder of the
respiratory organs.
x Degreasing agents such as trichlorethylene, tet-
rachloroethylene etc. vaporise during welding
and are chemically converted into phosgene.
Phosgene is poisonous!
UV-Rays
x The arc radiation can cause eye damage and
skin burns.
x For protection against sparks, heat, visible and
invisible rays suitable eye protection gear (weld-
ing visor or helmet with standardised filter
lenses to class 10 – 15 of DIN 4647, depending
on welding current) must be worn.
x Do not look into the arc with unprotected eyes
(risk of blinding and burns). The invisible ultra-
violet radiation causes, with insufficient eye pro
-
tection, a very painful conjunctivitis, which
appears only hours later.
x Weld only within the range of visibility of other
persons, who can assist you in an emergency.
x Other persons or helpers near the arc must be
made aware of the hazards, and equipped with
the necessary protective gear.
x Neighbouring workplaces are to be screened off
to provide protection against radiation.
x When welding inside rooms and buildings suffi-
cient ventilation must be ensured.
Fire
A
Danger!
The arc temperature is approx. 2400 °C.
Before starting to weld observe the following infor-
mation:
x Remove all combustible materials and objects
within a radius of 5 m from the welding point.
x Materials that can not be removed within a 5 m
radius must be protected by covering with sheet
metal, wet cloths etc.
x Any wall openings, cracks and the like must be
covered or sealed respectively, to prevent
uncontrolled flying of sparks.
x Keep fire extinguishing equipment such as fire
extinguisher, water pale etc. at hand.
x Keep in mind that by heat dissipation from the
welding point a fire may be started on covered
parts or in other rooms respectively.
x After completion of the welding work check the
vicinity of the welding point several times within
a period of 6 – 8 hours for heat conduction,
glowing combustion spots, hidden seats of fire
etc.
Handling of Shielding Gas Cylinders
x Observe all applicable regulations pertaining to
the handling of gas cylinders. Because of the
dangerously high internal pressure (up to 200
bar) shielding gas cylinders are to be specially
protected against mechanical damage, falling
over or falling down, heating up (max. 50°C),
prolonged radiation by sunlight and heavy frost.
x When the welding machine is equipped with a
gas cylinder too large in size this can cause, on
uneven ground, the welding machine to fall
over. To prevent subsequent damage to the
welding machine or the gas cylinder, use only
proper size gas cylinders (10l / 20l cylinders).
x Have cylinders refilled only by authorised filling
stations.
Electrical Hazards
x The connection to power mains and servicing of
the welding machine is to be done in accord-
ance with VDE regulations or other standards
applicable in your area.
x Ensure proper protective bonding of the supply
circuit.
x Ensure proper protective bonding of the work-
bench.
x Any service or maintenance work must only be
carried out by qualified personnel.
x Replace defective or damaged parts of torch or
torch leads without delay.
x The unit must only be connected to an earthed
outlet as a matter of principle. Only connections,
including outlets and extension cables with an
earthed plug, having an earth conductor and
installed by a qualified electrician, are permitted.
x The fuse protection of the supply circuit must be
in accordance with local regulations. According
to these regulations fuses or miniature circuit
breakers respectively, suitable for the conductor
cross section, must be installed. Installation of a
fuse with to high an ampere rating may cause
line fire and subsequent fire damage to the
building.
x Replace damaged torch insulation and welding
cables without delay.
x Replacement of a damaged power cable, plug
etc. and repairs to the electrical components of
the welding machine must be left to a qualified
electrician.
x Welding torches must not be held in an armlock,
or in such way that electricity can run through
the body.
