Risks From Mains Current And Welding Current - Fronius TransPocket 4000 CEL Instructions De Service

Welding must not be performed in areas that are subject to fire or explosion or near sea-
led tanks, vessels or pipes unless these have been prepared in accordance with the rele-
vant 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 rol-
lers 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, insula-
ted wirefeeder holder.
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 secured, undamaged, insulated and adequately dimensio-
ned. 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 pre-load.
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 elec-
trodes 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.
The device must only be operated on a mains supply with a ground conductor and a
socket with a ground conductor contact.
Operating the device on a grid without a ground conductor and in a socket without a
ground conductor contact will be deemed gross negligence. The manufacturer shall not
be held liable for any damage arising from such usage.
If necessary, provide an adequate earth connection for the workpiece.
Switch off unused devices.
Wear a safety harness if working at height.
Before working on the device, switch it off and pull out the mains plug.
Attach a clearly legible and easy-to-understand warning sign to the device to prevent
anyone from plugging the mains plug back in and switching it on again.
After opening the device:
-
-
never be immersed in liquid for cooling
Never touch the electrode when the power source is switched on.
Discharge all live components
Ensure that all components in the device are de-energised
