conditions
Height above sea level:
≤
1000 m
Operating temperature range: -10 ~ +40 °C
Relative humidity under r 90%
The device was designed for use in roofed rooms and must be installed in a dry environment. The ambient air in
which the plasma cutter is used should have a temperature below +40°C and low humidity. The ambient air must
be free of dust, acids, salts or concentrations of iron or metal powders.
Make sure there is enough free space in front of the unit so that the controls can be easily reached and seen.
Position the unit so that the air inlet and outlet are not obstructed (minimum distance to the wall 40 cm). Do not
cover the unit. Make sure that no metal parts, dust or other foreign bodies can enter the unit.
The housing ensures the protection of the electrical components against external influences as well as against
direct contacts. It has different degrees of protection against the ingress of solid bodies and water depending on
the situations in which they may be used. The degree of protection is indicated by the letters IP followed by two
digits: The first digit indicates the degree of protection against solid bodies and the second the degree of protection
against water.
The environmental conditions must be appropriate for protection class IP21!

NOTE:
Position the welding device so that the air inlet and outlet are not obstructed. The specified duty cycle
of the power units can only be achieved with sufficient ventilation (see "Technical data"). Make sure
that no grinding chips, dust or other metal parts can enter the unit.
