SECTION 4. – USING THE PLASMA CUTTER
4.1 - OPERATION
IMPORTANT
BEFORE TURNING YOUR UNIT ON OR OFF MAKE SURE THE AMP REGULATION IS SET
TO THE MINIMUM SETTING. FAILURE TO DO SO MAY LEAD TO DAMAGE TO THE UNIT.
A. TO BEGIN
Turn the Power Switch to the ON position.
Once unit is powered on, allow unit to sit for 1
min before making first cut.
Position yourself to where you can read the air
pressure. Press the torch switch (air will
exhaust from the torch, adjust the air regulator
to read approximately 20 – 60 PSI) release the
switch.
Secure ground clamp to work piece. Connect
clamp to main part of work piece.
Not the part
being removed.
B. CUTTING
1) DRAG
CUTTING
Position torch tip slightly above the work
piece, press torch switch and lower torch tip
toward work piece until contract is made and
cutting arc is established. After cutting arc is
established, move the torch in the desired
direction keeping the torch tip slightly angled.
Maintain contact with the work piece.
Move the torch just fast enough to maintain
spark concentration under the work piece. If
sparks radiate above the work piece, you are
moving too fast.
2) STAND-OFF
CUTTING
In some cases it may be beneficial to cut with
the torch tip raised above the work piece.
Raise the torch tip between 1/16” and 1/8
””
of
an inch above the work piece.
You can use the stand-off method during a
penetration or gouging method of cutting.
Additionally, you can use stand-off cutting
while cutting sheet metal to reduce the
chance of splatter-back tip damage.
3) PIERCING
For piercing, position the tip approximately
1/8” above the work piece. Angle the torch
slightly to direct the sparks away from the
torch tip and operator.
Initiate the arc and lower the tip of the torch
until the main cutting arc transfers.
Start the pierce off the cutting line on the
scrap piece or template and then continue
the cut onto the cutting line.
Hold the torch perpendicular to the work
piece after the pierce is complete and
continue cutting as desired.
Clean spatter and scale from the shield cup
and the tip as soon as possible.
