6) Input Power LED: LED illuminates green
when the MicroCut 875SC is properly
connected to a 220 volt input power supply
and the Power Switch (#8) is turned on.
7) Reset Button: When you turn on the MicroCut
875SC, the Safety Alarm LED (#3) illuminates
red. If the MicroCut 875SC is properly
connected to a power supply, the air supply is
sufficient, and the torch is installed correctly,
pressing the Reset Button will turn off the
Safety Alarm LED and you can begin cutting.
8) Power Switch: Turning the Power Switch on
will supply 220 volts of power to your
MicroCut 875SC. When you finish working
with the plasma cutter, turn the Power Switch
off.
9) Gas Purge Button: Allows you to purge air
through the cutting torch, manually cool the
cutting torch after long periods of cutting, and
set the air pressure as air flows through the
torch. To purge the torch, press the gas purge
button; air will flow and then stop flowing
automatically.
10) Manual/Automatic Cutting Switch: Allows
you to select between manual and automatic
cutting. When cutting manually, the arc will
extinguish after losing contact with the
workpiece. To reignite the arc and start
cutting again, you need to release and then
depress the trigger. When cutting
automatically, the arc reignites automatically
after losing contact with the workpiece.
Automatic cutting is ideal when cutting
expanded metal.
Setup
Plasma Torch Connection
Before installing the plasma cutting torch,
disconnect power to the machine. The MicroCut
875SC features a quick disconnect style cutting
torch, which means you can easily remove and
install the torch without any tools.
To install the cutting torch, insert the copper plug
on the torch into the center of the adapter block
on the front of the MicroCut 875SC (See Fig. 3,
#1). Rotate the plasma torch until the plastic tab
on the plasma torch fits into the cutout at the top
of the adapter block. Firmly push the plasma torch
into the adapter block and tighten the adapter nut
to secure the torch in place.
Ground Cable Connection
Connect the ground cable to the front of the
MicroCut 875SC (See Fig. 3, #11). To install, align
the tab on the ground plug with the notch in the
receptacle, insert the plug, and twist clockwise to
lock into place.
Connect the ground clamp to clean and clear
metal as close to the workpiece as possible in
order to reduce current loss through stray paths.
Do not, however, connect the ground clamp to
metal that you will cut off.

close the to cutting arc as possible.
