• non­contact cutting is applied in automatic
cutting.
• Remove the torch wheel and then install accord­
ing to the following picture: K

• Keep the cable of semiautomatic cutter well con­
nected, connect the leading trail or radial pole
according to the shape of the cutting work piece.
(apply the leading trail if it is for beeline cutting:
apply the radial pole if it is for round cutting or
round pilot)
• Pull out the connector of the torch and change
with the remote control plug (optional)
• Adjust suitable speed according to the thickness
of the work piece, and adjust the inverse ordinal
switch to the cutting direction
• Turn on the remote control to establish the plasma
pilot, after cutting through the working piece,
turn on the power supply of semi­automatic cut­
ter to start cutting, keep an eye on the cutting slot
to adjust a suitable cutting speed during the cut­
ting phase.
• Turn off the remote control switch when cutting
ends, and then withdraw the torch and the cut­
ting ends.
Manual Round Cutting
• Install the torch according to the following sketch
and adjust the length of the rail as per the radii of
work piece.

• Manual round cutting or round pilot cutting
according to different cutting type.

Notice while cutting
• If unnecessary, please do not ignite the leading
pilot in the air, or it will reduce life­span of the
torch's electrode and puzzle.
• It will be better to start cutting at the edge of the
work piece, unless you must do perforation oper­
ation on the work piece.
• Be sure that the splash is spilt from the bottom
Torch
of the work piece. If it is spilt from the top of the
work piece, then you must move the torch too
Holder
quickly, or the thickness you chose could not cut
through the work piece.
• Keep certain space between the nozzle and the
Work piece
work space. If press the torch onto the work piece
heavily, it will make the nozzle stick onto the work
piece, thus it can not move smoothly to cut.
• Templet or accessorial equipment is required to
cut round work piece and edge inosculation work
piece.
• It is easier to "pull" than "push" during the cut­
ting process
• Keep the torch's nozzle vertical against the work
piece, and observe if the pilot is moving along
the cutting line.
• While cutting the thin work piece, the thin mode
can get best cutting quality with low wastage and
longer life span of electrode and nozzle.
• Do not repeat to press the torch switch rapidly,
otherwise the pilot system and relative work piece
will be destroyed.
• The Non­HF Arc­pilot Series cutter's working
range is 0.4∼0.45MPa. HF Arc-pilot Series cut­
ter's working range is 0.4∼0.55MPa.

Safety Requirement

• Never allow the electrophorus torch to aim at any
part of the body.
• Make sure to wear protection glasses and protec­
tion glove while operating.
• Make sure to work in places where there are
exhaust or ventilation facilities to keep fumes or
emissions away from the breathing zone.
• No touching to the work piece while cutting in
case of the creep age leading into accident.
• Never allow to cut the vessel that is or was with
flammable or explosive stuff
• Torch cable is not allowed to work under water
or in the moist environment
• The puckering angle of the torch cable can not
be too small, otherwise the inside cable of gas
pipe will be damaged which can result into
accident.
• Never allow anybody else other than the opera­
tor himself to access the working area.
• Make sure to turn off the power supply when dis­
mantling or moving the machine
