5.2.2 Environmental Requirements
Verify the DCX S Power Supply is operated in an environment that meets the temperature
and humidity requirements indicated in Table 5.1 Environmental Requirements.
5.2.3 Electrical Input Power Ratings
Connect the power supply to a single-phase, grounded, 3-wire, 50 Hz or 60 Hz 200 V to
230 V power source. Table 5.2 Input Current and Circuit Breaker Specifications lists the
current and breaker ratings for the various models.
5.2.4 Pneumatic Requirements
Your welding system may require a cooling air stream for the converters. In continuous
operations, or applications with longer duty cycles, it may be necessary to cool the horn as
well as the converter.
Typically 80 cubic feet (2.26 m
3
) per hour of clean, dry, compressed air are required to
cool most welding operations.
To verify the 80 cubic feet (2.26 m
3
) per hour cooling air stream required for your welding
system, refer to 5.6 Converter Cooling.
