power cord to a properly grounded
230 VAC (220V - 240V), 60 HZ, single
phase, 50A power source. If operating
on 120V, attach the 120V Adapter cord
to the unit power cord and then
connect the assembly to a properly
grounded 120 VAC (110V-130V), 60 Hz,
single phase, 20A power source.
1. SET UP
a. Check the plasma cutter to see if it
has been connected correctly and is in
good working condition as described
in INSTALLATION Section and that it
complies with safe operation
requirements as noted in the
IMPORTANT SAFETY
CONSIDERATIONS Section.
b. Switch on the power switch of the
cutter to observe if the operation is
normal. If it is normal, the fan should
start up and the Power Indicator Light
should be on. If there is no compressed
air or the air pressure is low the Low-
Pressure Indicator Light will be on.
c. Adjust the air supply valve until the air
pressure is up to the cutting torch
requirement. (Lowest pressure should
be no less than 50psi), the Low-
Pressure Indicator Light will not be lit
up in those conditions.
d. Adjust the air flow to be sure it is
consistent.
e. Pull the torch trigger. The cutting
operation begins after the cutting
plasma pilot arc is made.
2. CUTTING OPERATION
2.1. Metal Sheet Cutting
a. Put the torch’s nozzle at the start
of the work piece. Turn on the
torch switch to ignite the plasma
pilot. After the work piece is cut
through, move the torch along the
cutting direction uniformly. The
cutting speed is determined by
watching to see if the cutting goes
all the way through. If the speed is
too fast, the work piece won’t be
cut through, or if too slow, the cut
quality
would
be
affected,
excessive warping may occur, or
the arc could stop.
b. When you’ve completed the
cutting process, turn off the torch;
the plasma pilot arc will stop.
2.2. Metal Mesh Cutting
a. Fix the work piece and connect the
earth cable with the work piece.
b. Put the cutting nozzle onto the
work piece, lift torch up slightly
from the work piece and turn on
the switch to cut.
2.3. Notice while cutting
a. Unnecessary igniting of the pilot
arc in the air will reduce the
lifespan of the torch’s electrode
and nozzle.
b. It is best to start cutting at the edge
of the work piece, unless you are
piercing the work piece.
c. Keep a space between the nozzle
and the work piece. Pressing the
nozzle on the work piece could
