Danger From Flying Sparks; Risks From Mains Current And Welding Current - Fronius TransTig 1750 Puls Operating Instructions Manual

Danger from fly-
ing sparks
Risks from mains
current and weld-
ing current
Flying sparks may cause fires or explosions.
Never weld close to flammable materials.
Flammable materials must be at least 11 metres (35 ft) 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 in-
jury 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.
An electric shock is life threatening and can be fatal.
Do not touch live parts either inside or outside the device.
During MIG/MAG or TIG welding, the welding wire, the wirespool, the drive
rollers and all metal parts that are in contact with the welding wire are live.
Always set the wire-feed unit up on a sufficiently insulated surface or use a
suitable, insulated wire-feed unit mount.
Make sure that you and others are protected with an adequately insulated, dry
temporary backing or cover for the earth or ground potential. This temporary
backing or cover must extend over the entire area between the body and the
earth or ground potential.
All cables and leads must be complete, undamaged, insulated and adequately
dimensioned. Loose connections, scorched, damaged or inadequately dimen-
sioned cables and leads must be repaired/replaced immediately.
Do not sling cables or leads around either the body or parts of the body.
The electrode (rod electrode, tungsten electrode, welding wire, etc) must
- never be immersed in liquid for cooling
- never be touched when current is flowing.
Double the open circuit voltage of a welding machine can occur between the
welding electrodes of two welding machines. Touching the potentials of both
electrodes at the same time may under certain circumstances be fatal.
