Automatic/manual pressure setting mode selector
The selector switches between automatic and manual mode. In automatic mode,
the power supply automatically sets the gas pressure based upon the torch type
and lead length and the adjustment knob sets only the amperage. In manual mode,
the adjustment knob sets either the gas pressure or the amperage. This LED is
illuminated in manual mode.
ote:N Manual mode should be used by experienced users who need to
optimize the gas setting (override the automatic gas setting) for a
specific cutting application.
When you switch from manual mode to automatic mode, the power supply
automatically sets the gas pressure and the amperage setting is unchanged. When
you switch from automatic mode to manual mode, the power supply remembers the
previous manual gas pressure setting and the amperage setting is unchanged.
When you reset the power, the power supply remembers the previous mode, gas
pressure, and amperage settings.
Current/gas selector
When in manual mode, this selector toggles between amperage and gas pressure
for manual adjustments using the adjustment knob.
Adjustment knob
This knob adjusts the amperage. When operating in manual mode, this
knob can also adjust the gas pressure, overriding the automatic setting for
optimized applications.
