High Frequency Interference - ESAB EMP 285ic 1ph Instruction Manual

5.2

HIGH FREQUENCY INTERFERENCE

WARNING
The high frequency section of this machine has an output like a radio transmitter.
The machine should NOT be used near blasting operations due to the danger of premature
firing.
WARNING
Operation close to computer installations may cause computer malfunction.
WARNING
HIGH FREQUENCY FIELDS CAN BE DANGEROUS TO HEALTH. Extra precautions may be required
when this welding power source is used in a domestic situation. Welders with medical
pacemakers should consult their doctor before welding. EMF may interfere with some
pacemakers.
WARNING
The welding circuit may or may not be earthed for safety reasons. Changing the earthing
arrangements should only be authorized by a person who is competent to assess whether the
changes will increase the risk of injury, for example: by allowing parallel welding current return
paths which may damage the earth circuits of other equipment.
WARNING
Equipotential Bonding:
Bonding of all metallic components in the welding installation and adjacent to it might be
considered. However, metallic components bonded to the work piece will increase the risk that
the operator could receive a shock by touching the metallic components and the electrode at
the same time. The operator should be insulated from all such bonded metallic components.
WARNING
Earthing/Grounding of the work place:
Care should be taken to prevent the earthing of the work piece increasing the risk of injury to
users, or damage to other electrical equipment. Changing the earthing arrangements should
only be authorized by a person who is competent to assess whether the changes will increase
the risk of injury.
