Danger From Flying Sparks; Risks From Mains Current And Welding Current - Fronius TransPocket 4000 CEL Bedienungsanleitung

Flammable vapours (e.g. solvent fumes) should be kept away from the arc's radia-
tion area.
Close the shielding gas cylinder valve or main gas supply if no welding is taking
place.
Danger from fly-
Flying sparks may cause fires or explosions.
ing sparks
Never weld close to flammable materials.
Flammable materials must be at least 11 metres (36 ft. 1.07 in.) away from the
arc, or alternatively covered with an approved cover.
A suitable, tested fire extinguisher must be available and ready for use.
Sparks and pieces of hot metal may also get into adjacent areas through small
gaps or openings. Take appropriate precautions to prevent any danger of injury or
fire.
Welding must not be performed in areas that are subject to fire or explosion or
near sealed tanks, vessels or pipes unless these have been prepared in ac-
cordance with the relevant national and international standards.
Do not carry out welding on containers that are being or have been used to store
gases, propellants, mineral oils or similar products. Residues pose an explosive
hazard.
Risks from mains An electric shock is potentially life threatening and can be fatal.
current and wel-
Do not touch live parts either inside or outside the device.
ding current
During MIG/MAG welding and TIG welding, the welding wire, the wirespool, the
feed rollers and all pieces of metal that are in contact with the welding wire are
live.
Always set the wirefeeder up on a sufficiently insulated surface or use a suitable,
insulated wirefeeder holder.
Make sure that you and others are protected with an adequately insulated, dry
base or cover for the earth or ground potential. This base or cover must extend
over the entire area between the body and the earth or ground potential.
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.
Use the handle to ensure the power connections are tight before every use.
In the case of power cables with a bayonet connector, rotate the power cable
around the longitudinal axis by at least 180° and pretension.
Do not wrap cables or leads around the body or parts of the body.
The electrode (rod electrode, tungsten electrode, welding wire, etc.) must

Double the open circuit voltage of a power source can occur between the welding
electrodes of two power sources. Touching the potentials of both electrodes at
the same time may be fatal under certain circumstances.
Arrange for the mains cable to be checked regularly by a qualified electrician to
ensure the ground conductor is functioning properly.
never be immersed in liquid for cooling
Never touch the electrode when the power source is switched on.
