carrying out maintenance and repair
work! The welder becomes hot during
use! Improper handling of the welder can
lead to burns or injuries.
r) Disconnect the mains plug before any
maintenance and repair work.
Additional safety instructions for
welding
Additional safety instructions
for connecting the welder to
electrical sockets
a) Before switching on, make sure that
there is no contact with ground.
If the
electrode or torch makes contact with the
ground, an arc can be generated when
switched on. A carelessly placed electrode
holder may result in burns and damage
if it comes into contact with ground. You
could get burns.
b) After completing the work, always
switch off the welder.
c) Do not touch any parts without checking
the temperature. Arc welding produces
sparks and drops of molten metal. The
workpiece becomes so hot that it begins
to glow and stays hot for a long period.
d) Do not allow cables to become
entangled around your body during
work.
e) Avoid any direct contact with the
welding current circuit. The electrode
holder and the earth must always be on
the same side.
f) Do not use the welder to defrost pipes.
g) Disconnect the device from the mains
immediately after finishing the welding
work.
h) Always cover your eyes with suitable
protective goggles when using the
chipping hammer. Slag is hard and brittle
after solidification. Using the chipping
hammer on the hardened slag can cause
sharp pieces to break off and cause eye
injuries.
The connection should be done via a socket
with 16 Amps fuse. The lines of the power
socket have to be designed for this power.
The fuses amperage rating must not be too
high in order to prevent damage to the
electrical lines.
a) Prevent unintentional start-up. Ensure
that the welder is switched off before you
connect it to the power supply.
b) Connect the welder only if the mains
voltage of the socket matches the
specifications on the type plate.
c) Do not use the mains cable for
unintended purposes, such as carrying
the welder or to pull the plug from the
socket.
d) Keep the mains cable away from heat,
oil, sharp edges and do not bend it.
e) Connect the welder only to an easily
accessible socket, so you can disconnect
the welder quickly from the mains in case
of malfunction.
f) If an extension cable is required,
ensure that the conductors are of
sufficient diameter to carry the current
drawn by the welder. Minimum cross
section 1.5 mm2.
g) Use cable reels only in fully unrolled
condition.
h) Check the mains cable. Never use faulty
or damaged mains cables.
Precautions against electric shock
If the arc does not ignite, there may be
an open circuit U0 between the earthing
clamp and the contact tip. The open circuit
voltage can be dangerous if the torch, the
nozzle, the welding wire or the workpiece
are handled without protective equipment.
