Hazards from
mains and weld-
ing current
Sparks and hot metal particles may also get into surrounding areas through
small cracks and openings. Take suitable measures here to ensure that
there is no risk of injury or fire.
Do not perform welding in locations that are at risk from fire and/or
explosion, or in enclosed tanks, barrels or pipes, unless these latter have
been prepared for welding in accordance with the relevant national and
international standards.
Welding must NEVER be performed on containers that have had gases,
fuels, mineral oils etc. stored in them. Even small traces of these
substances left in the containers are a major explosion hazard.
An electric shock can be fatal. Every electric shock is hazardous to life.
Do not touch any live parts, either inside or outside the machine.
In TIG hot-wire welding, the welding wire, the wire spool, the drive rollers
and all metal parts that are in contact with the welding wire may also be
electrically live.
The wirefeeder units / wire-drives for TIG hot-wire must always be placed on
a sufficiently insulated base or floor surface, or on a suitable insulating
wirefeeder holder.
Ensure sufficient protection for yourself and for other people by means of a
dry base or cover that provides adequate insulation against the ground/
frame potential. The base or cover must completely cover the entire area
between your body and the ground/frame potential.
All cables, hosepacks and other leads must be firmly attached, undamaged,
properly insulated and adequately dimensioned. Immediately replace any
loose connections, scorched, damaged or underdimensioned cables,
hosepacks or other leads.
The cables for pre-heating the welding wire, and for the pre-heating system
itself, must be sufficiently insulated and dimensioned, heat-resistant, and
approved by Fronius for use with the TP 1500 RC HD power source.
Do not loop any cables, hosepacks or other leads around your body or any
part of your body.
Never immerse the welding electrode (rod electrode, tungsten electrode,
welding wire, ...) in liquid in order to cool it, and never touch it when the
power source is ON.
Twice the open-circuit voltage of one single welding machine may occur
between the welding electrodes of two welding machines. Touching the
potentials of both electrodes simultaneously may be fatal.
Have the mains and the machine supply leads checked regularly by a
qualified electrician to ensure that the PE (protective earth) conductor is
functioning correctly.
Only run the machine on a mains network with a PE conductor, and plugged
into a power outlet socket with a protective-conductor contact.
