1) Plasma Torch Receptacle: Connection for the
plasma cutting torch. If installed incorrectly,
the cutter will not operate.
2) Cutting Current Adjustment: Controls the
cutting amperage of the MicroCut 875SC.
Infinitely variable from 30 to 55 amps.
3) Safety Alarm LED: LED illuminates red when
you power on the MicroCut 875SC. Pressing
the reset button (#7) turns the Safety Alarm
LED off. If the Safety Alarm LED does not turn
off after pressing the reset button, either the
plasma torch is installed incorrectly, the
consumables are not installed correctly, or
the air pressure is set too low.
4) Thermo Switch LED: LED illuminates yellow if
you exceed the duty cycle (40% at 55 amps)
of the MicroCut 875SC. If you exceed the duty
cycle of the cutter, leave the machine on,
allowing the cooling fan to run. When the
cutter cools, the Thermo Switch LED will turn
off.
5) Air Pressure LED: LED illuminates green
when properly connected to an air supply.
The pressure gauge on the regulator should
read above 70 psi; if the air pressure falls
below 70 psi, the Air Pressure LED will shut
off and the Safety Alarm LED will turn on,
illuminating red.
