* Please read carefully this manual before use the system.

Attention:

1) After open the package , please check the goods is in good condition and everything

is there .

2) This manual is only for Portable Flame/Plasma cutting machine system which

produced by TOMATECH TECHNOLOGY CO.,LTD.

3) Working environment temperature is 0-40℃. Relative humidity should be controlled

in 0-85%.Special protection is necessary when under high-temperature,high-humidity

4) In order to make sure operator’s safety and controller working properly , CNC

controller and other devices all should be earth connected.

5) The system operator should be well-trained and familiar with the system before

operating.

6) The inside power supply of CNC controller does not allow connecting with other

3.3、Speed Mode（SCALE） and auto cutting ignition

3.3.1 Moving Speed
In no-load moving mod, torch is moving at the maximum moving speed X speed ratio. User should only adjust
to speed ratio to change speed of cutting machine.
3.3.2 Cutting Speed
In cutting mode， actual speed is cutting speed limit X cutting ratio auto ratio adjustment can be achieved by
F+/F- during cutting. Under non-cutting mode, press【H】cutting speed to adjust ratio by pressing F+/F-.
3.3.3 Backing Speed
Under backing mode, backing speed is cutting speed X backing ratio， Backing ratio can be adjusted by F+/F-.

Once all three-speed settings are finished, speed properties will be saved automatically, and not affected by
powering off the machine.

3.3.4、Auto Mode Ignition

1) Before auto cutting starts
To select proper cutting program, choose the suitable cutting speed ratio. Put torch on the cutting position
（Torch will be lifted up after program initializes（executes M70））,after other preparation works are
done, the program may start auto mode execution.

2) Two ways to initialize auto mode:

Flame / Plasma CNC Cutting System Operating Manual 12

 TOMATECH AUTOMATION CO.,LIMITED www.tomatech-cnc.com
a) Green 【START】 button on control panel；

b) Press exterior “START” button

3.4 Under following operations, torch can be moved in order to change positions.

（1） Pause，（2）Backing，（3）Piercing，（4）Select（5）Find breaking point.

Under above conditions, users could press 【↑】【↓】【←】【→】 directly to change torch position（Current
system speed ratio is manual adjustable）。After moving to desired position, press【START】 button，display is
shown as below.

Picture3.3 position adjustment

1）Return to origin point dialogue
Suggestion, press 【PIERCE】 after pre-heating, thus, system starting cutting from the origin point.
2) Return to previous cutting point
Pierce first，applying cutting speed to return to original point, keeping cutting following the previous track.
3) Pierce under current hole
Pierce first, take present coordinates as “adjusting point”

Leaving cutting mode

When in pause, press 【ESC】 to return main menu.

3.5、Break point processing

3.5.1. Break point resume
1) When system is in pause or accidentally power off; system saves current torch position as a break point.
The break point is permanent whether system is turned off or not.
2) Under auto mode, as long as the cutting program does not change, press 【F2】 select break point function,
then press 【START】 button, system resumes working from break point.
3) If the torch position did not change, system would call attention to BRK point after system finds the break
point.
4) If the torch position changed (not on break point), system would display following three options after
system finds break point.

 TOMATECH AUTOMATION CO.,LIMITED www.tomatech-cnc.com

Picture3.5 system pause、finds break point then resumes cutting dialogue

a) Back to original
b) Back to cutting point
c) Pierce at current position

HINT：Press 【PIERCE】 after pre-heating, then system would resume cutting from break point.

Press 【ESC】，system leaves cutting mode.

3.5.2 ATTENTION:
Once the cutting program is changed, BREAK POINT will be eliminated from system cache, thus the
system would not be able to find BREAK POINT and would not resume working.

3.6、 SELECT MODE

3.6.1、START SELECT MODE
Select to cut from any section of the cutting program then press 【START】，
Press【F1】to choose SELECT function, the system will be shown as below:

Picture 3.5 selections Menu

Meanwhile：use 【↑】【↓】 to move the curser to choose either SELECT mode to cut
According to the choice, system would choose order number to process.

3.7、Edge piercing of thick sheet

In auto mode, edge piercing is more suitable for thick sheet.
1) Solution of edge piercing：Move the torch to sheet edge before piercing.
2) Start pre-heating. Press【START】button after pre-heat ends. Torch moves linear distance at pre-set speed
to the piercing position, resumes cutting.
3) In edge piercing, select figure from control menu to set “edge piercing” to 1, means such function is enacted.

Chapter 10 Controller Input/output Port Connection

The controller’s ports include input (DB25 pin) output (DB25 pin) motor 1 (9 pin) motor 2 (9 pin)
RS232 serial port (9 pin), RS232 connect hand-controller, details is appendix 3.
10.1 Outside Motor Driver Port

Notice:
1. If the controller is using for plasma cutting , Connection cable between CNC controller and servo/stepper
driver must be shield cable. All devices must be connected with ground. The shielded cable’s shielded copper
mesh must be connected with ground as well.
2. If the equipment needs dual-side drive (Synchronous axis ), please use the Motor 2 Signal Port.
3. If the stepper driver signal is common anode connection, VCC connects the common anode port, “direction
“and “pulse “ connect driver’s direction and pulse pins.

10.2.2 Connection for “Emergent Stop” Input Signal
“Emergent stop” input signal is different from other input signals. There are two connection options:
Option 1: only use the controller panel’s “emergent stop” Method:
Short circuit the controller input port pin 23 and pin 16 (STOP). as below picture shows

Option 2: Internal emergent stop and external emergent stop (i.e. outside connection emergent stop) are both
available:
Connect the emergent stop switch between pin 23 (from inside emergent stop) and pin 16 (STOP).
As below picture shows:

SF2300software upgrades instructions
1、operating steps
1. The first U disk will be formatted with the FAT or FAT32 format, suggested the use of FAT format.
2. Will update the files into the U disk, upgrade file name must be STARTCNC.EXE.
3. Open the system back, on the floor, there is a 3P pin J17, inserted above a short way, should be inserted in the

working condition Upgrade status
4. Open the system power supply, power on the system, the U disk is inserted in the U system;
5. The system automatically upgraded into the interface, press the F1 button on the panel (i.e. the upgrade of the
corresponding key); the system will prompt: "began to upgrade, please ensure that you have inserted U disk....."; if not

insert U disk, the system will stay in this interface.

6. If the upgrade is normal, after the upgrade is complete, the system will display "the upgrade was successful!".
7. Turn off the power, unplug the U disk, the upgrade process completed..

2、Upgrading from state to a working state

The short circuit of the electronic change to "work" as shown above, open the system power, system power on again,
the new version of the program is displayed on screen.

Attention:
1. The reason of upgrade failed more is caused by U disk, if system have not hint the U
Disk’s operation course, please instead U disk and try again.
