used for emergency case.
3.4.2.Adjustment of cutting position
3.4.2.1Situations necessary to adjust the position of cutting torch:
1)If the cutting torch is blocked or replacement is necessary, the usual practice is to move the cutting torch to
somewhere safe and move it back to the starting point after the situation is resolved.
2)When it is required to pierce along the exterior margin and not position the piercing point at the exterior
edge, the usual practice is to pinpoint an appropriate position in the exterior of workpiece for piercing and
then cut the workpiece back to the starting point along a straight line before continue normal machining
without stop.
3) In case of transitional cutting, too many workpiece or large size of workpiece, it might be necessary to
relocate the cutting torch.
3.4.2.2Situations allowed to adjust the cutting position:
(1) pause process, (2) return process,(3) piercing process, (4) section selection, (5) hole
selection and (6) breakpoint restoration
If operator intends to change the position of cutting torch in the above-mentioned states, it is allowed to
press [↑], [↓], [←] and/or [→] key to do so(in this case, it is manual multiplying factor, adjustable). When
the expected position is reached, press [Start] key, as shown in the following dialog box:
1)ORIPATHRET(originalpathreturn)
Returnthe cutting torch to the adjustmentbeginning point at speed G00and wait forother operation;at this step,it is allowed

return or advancing.
3.5.3 Operation after returned
After the cutting torch returns to the designated position, it is allowed to select position adjustment of cutting
torch(refer to 3.4) or piercing directly by pressing the appropriate heavy-current function key such as
PREHEA(piercing preheat) and CUT(cutting oxygen).
It is common practice to--
Press [PIERCE] key after preheating operation is done, or
For flame cutting operation, press CUT key(open the cutting oxygen) if the cutting torch lifts or
continue machining if the cutting torch lowers; or
For plasma cutting operation, ignite arc and do not go on machining until the arc ignition is
completed.
3.5.4 Repeat the above operation procedure until the desired effect is achieved.
3.5.5 To exit machining mode
In pause state, press [ESC] key to exit machining mode.
3.5.6 Total row number and beginning row in return process
The program segment for return allows 300 rows maximum. In case of breakpoint restoration(RESBREK) or
machining section selection(SECTION), the return beginning row is the row containing the current
breakpoint or the section selecting row, upon which however the cutting torch is not allowed to return along
the original path for machining.

current position of cutting torch as a breakpoint, which will be kept permanently in the system, whether
power the system off or not.
2) In automatic mode, press [F2] key to select RESBREK function and then [START] key to start breakpoint
restoration as long as there is no change with the current program.
3) If the position of cutting torch does not change, the system will prompt "Breakpoint" when a breakpoint is
found and wait for subsequent command. User may select piercing directly or position adjustment of
cutting torch. Refer to 3.4 for details.
4) If the position of cutting torch does change and is off from the breakpoint, the system will provide three
options when a program breakpoint is found, which is virtually position adjustment of cutting torch.
ORI PATH RET: To return to the breakpoint at speed G00, which is often used for the breakpoint set for cutting torch
replacement;
CUT RET: little bit off from the breakpoint after breakpoint restoration, whic is somewhat like piercing along the exterior
margin,makingthebreakpointmoresmooth;
HOLEHERE:thesameoperationasprevious,whichcanalsobeusedfortransitionalcutting.
Now, it is allowed to press a heavy-current function keysuch as IGN(ignition), PREHEA(piercing preheat), CUT(cutting
oxygen),etc.
Tip:Thesystemwillcontinuetoprocessfromthebreakpointlocationif[PIERCE]keyispressedafterpreheating.
If press [ESC] key when a breakpoint is found, the system will exit machining mode.
3.6.2Attention:
Never try to change the machining program, rotation angle and scaling proportion whether it is
breakpoint restoration or power-off restoration, which will be automatically saved by the system and
free from affect by power-off operation; otherwise, the system can not find the breakpoint.

b)If it is the expected piercing point, use heavy-current control switch for ignition and preheat before
press [PIERCE] key to start operation.
c) If "REFPOSITION" option(Reference Point Positioning) is selected, operator should aim the cutting
torch at the reference point. After started up, the system will control the cutting torch to reach the
piercing point and then perform the operations as above.
3.8. MOVE HOLE for Thick Plate
1) In automatic mode, MOVE HOLE option is taken for thick plate.
2) For edge piercing method, it is important to move the cutting torch to the nearest edge of steel plate
before piercing operation.
3) Preheat the system and press [START] key at the end of preheat. The cutting torch will cut the steel plate
along a straight line to the piercing point at selected cutting speed and then go on machining.
4) When MOVE HOLE option is taken, it needs to change the MOVE HOLE option to 1 in the parameter
control menu, thus to enables the option. In this way, whenever it is time for piercing operation, the system
will prompt an option menu as shown below:

manualmodeasfollows:
4.1.1 [↑], [↓], [←], [→] directional control keys and [G] Continue Key
Generally, if any of the four direction keys is pressed and held, appropriate axial movement will carry on
until the key is released. However, if [G] Continue key is pressed and highlighted before any direction key is
pressed, the cutting torch will keep moving even if the key is released. The movement will not stop until the
direction key is pressed again. If two axial movements are required, let one axial movement start first and then
press the direction key for the other axial movement. Two axial movement will go on simultaneously. In this
case, the axial movement of cutting torch will stop if the corresponding direction key is pressed while the other
axial movement will go on until the corresponding direction key is pressed too. [PAUSE] key will stop the
movement as well.
4.1.2 【F1】AUTO
The system is switched to automatic mode.
4.1.3 【F2】MOVE
If MOVE function(highlighted) is selected, the system will prompt to input MOVE INCREMENT:
0050.000 (previous input value by default). In MOVE mode, if direction key is pressed once, the cutting
torch will move an increment at the speed of the current maximum speed limit multiplied by multiplying
factor.
4.1.4 [F2]P-START, [F3]P-END and Calibration function
This feature is used when the steel plate is not positioned perfectly or the steel plate needs to rotate an angle
before machining. Let the cutting torch go along a straight edge as long as possible. Pick up two points([F2]
for setting P-START and [F3] for P-END). The system will calculate automatically the rotation angle. Select
the ROTATE function in automatic mode. After acknowledged, the system will start the machining program at
the appointed rotation angle.
Note: Counterclockwise direction is taken as positive angle.
