Risks From Mains Current And Welding Current - Fronius Artis 170 Operating Instructions Manual

Keep suitable, tested fire extinguishers on hand.
Sparks and pieces of hot metal may also get into surrounding areas through
small cracks and openings. Take appropriate measures to ensure that there is no
risk of injury or fire.
Do not undertake welding in areas at risk of fire and explosion, or on sealed
tanks, drums, or pipes if these have not been prepared in accordance with cor-
responding national and international standards.
Do not undertake welding on containers in which gases, fuels, mineral oils, and
the like are/were stored. Residues pose a risk of explosion.
Risks from mains An electric shock can be fatal.

Do not touch voltage-carrying parts inside or outside the device.
welding current
During MIG/MAG welding and TIG welding, the welding wire, the wire spool, the
feed rollers, as well as all pieces of metal that are in contact with the welding
wire, are live.
Always place the wirefeeder on a sufficiently insulated base or use a suitable in-
sulating wirefeeder holder.
Ensure suitable personal protection with dry temporary backing or cover with
sufficient insulation against the ground potential. The temporary backing or cov-
er must completely cover the entire area between the body and the ground po-
tential.
All cables and leads must be secured, undamaged, insulated, and adequately di-
mensioned. Replace loose connections and scorched, damaged, or inadequately
dimensioned cables and leads immediately.
Before every use, check power connections for secure fit by hand.
In the case of power cables with bayonet connectors, turn the power cable by at
least 180° around the longitudinal axis and pretension.
Do not wrap cables or leads around your body or parts of the body.
Concerning the electrode (stick electrode, tungsten electrode, welding wire, etc.)

The open circuit voltage of a welding system may double, for example, between
the electrodes of two welding systems. Touching the potentials of both elec-
trodes at the same time may be life-threatening in some cases.
Have the grid and device supply lead regularly inspected by an electrician to en-
sure that the ground conductor is functioning properly.
Protection class I devices require a grid with a ground conductor and a connector
system with ground conductor contact for proper operation.
Operation of the device on a grid without a ground conductor and on a socket
without a ground conductor contact is only permitted if all national regulations
for protective separation are observed.
Otherwise, this is considered gross negligence. The manufacturer accepts no li-
ability for any damage resulting from improper use.
Use suitable equipment to ensure that the workpiece is sufficiently grounded if
necessary.
Switch off unused devices.
