See Section 4.4, Gas Selection for Plasma Cutting, for
detailed information on operation with various plasma
and secondary options.
Maximum input gas pressure to the power supply's inter-
nal regulator must not exceed 125 psi (8.6 bar).
3.2 LOCATION
CAUTION
Select a clean, dry location with good ventilation and
adequate working space around all components.
The power supply is air cooled and air flow through the
front, rear, and side panels must not be obstructed. At least
two feet (0.61 m) of clearance should be provided on all
sides.
Operation without proper air flow will inhibit proper
cooling and reduce duty cycle.
Review Operating Precautions (page iv) to be sure that the
selected location meets all safety requirements.
