Warning!
REHM plasma cutting equipment may only be operated by persons who
have been trained and instructed in the use and maintenance of plasma
cutting equipment and in the safety provisions that apply thereto.
Working on and servicing electrical plasma cutting equipment is always
potentially hazardous. Personnel not familiar with such equipment and machinery
could hurt themselves or others. For this reason, operators must be told of the
potential hazards outlined below and of the safety measures that are necessary to
avoid possible injury. Irrespective of this, anyone operating plasma cutting
equipment must familiarise himself with the safety regulations that apply in the
relevant working area prior to starting work.
6.2 Electrical Hazards
Connection of and maintenance work on plasma cutting equipment and its
accessories may only be carried out in compliance with current VDE (association
of German electrical engineers) provisions and the regulations issued by the
appropriate safety authority. Ignition of the arc and cutting require a very high
voltage.
Warning!
The no-load voltage with plasma cutting equipment is over 100V.
- Never touch any live metal parts with the bare skin or with wet clothing.
- When cutting, always wear gloves and protective hoods fitted with approved
protective filters.
- Take care to ensure that all parts which you have to touch during your work,
such as your clothing, your working area, the welding torch, the electrode
holder and the plasma cutting equipment, are always dry.
- Take care to ensure that there is good insulation by only wearing dry gloves
and boots with rubber soles, and by standing on a dry, insulated base,
especially if you have to stand on metal during your work or are working in
areas with significant electrical hazards.
- Avoid using any power cables that are worn or damaged. Ensure that power
cables are not overloaded. Use only equipment that has no faults.
- Switch off the plasma cutting equipment whenever work is interrupted for any
length of time.
- Do not wind the cutting cable around any part of the housing and do not let it
lie wound up in coils.
- Never leave the plasma cutting equipment switched on and unsupervised.
- Only ignite the pilot arc against the work piece.
