* Please read carefully this manual before use the system.
Attention:
1) After open the packing case, please check the goods and whether accord with
the list.
2) This manual is only for Portable Flame/Plasma cutting machine system
produced by Beijing Start Microstep.
3) Operating environment temperature is 0-40℃. Relative humidity should be
controlled in 0-85%. Under high-temperature, high-humidity, caustic gas, must
adopt special defend measure.
4) In order to ensure control system working normally and improve system
reliability and ensure the operator’s safety; cutting machine tools and control
system all should be well earthed.
5) Control system should be insulated from outside to avoid dirt and powder
entering and result in control system working abnormally, system parts
damaged, etc.
6) The system operator should be well-trained and familiar with the system
before operating special operator.

7) The inside power source of CNC system does not allow connecting with other
electric apparatus.
8) Toward some area that power supply is nonstandard (such as zero line and
earth wire sharing or no zero line), in order to ensure control system working
normally and improve system reliability and sure operator’s safety, you must
use isolation transformer that three-phase/two-phase AC380V transfer to two-
phase AC220v between electric network and control system.
9) If problem existed, please contact our company. If don’t familiar with system,
are not allowed to take down system.
10)Output voltage for the control system is suitable only for use of the USB Disk;
and is not supposed to connect with other USB devices to avoid unexpected
damages.
11) Power of the system must be turned off while switching between touchpad
keyboard and exterior keyboard.
12) This operating manual is the property of Beijing Microstep Control
Technology. The final explanation right of this manual belongs to Beijing

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:
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.
1）Returntooriginpoint
Suggestion, press 【PIERCE】after pre-heating, thus, system starting cutting from the origin
point.
2)Return topreviouscuttingpoint

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.
a) Backtooriginal
b) Backtocuttingpoint
c) Pierceatcurrentposition
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、SELECTMODE
3.6.1、STARTSELECTMODE
Selecttocutfromanysectionofthecuttingprogramthenpress 【START】，
Press【F1】to choose SELECT function, the system will be shown as below:

Meanwhile：use 【↑】【 ↓】to move the curser to choose either SELECT mode to cut
Accordingtothechoice,systemwouldchooseordernumbertoprocess.
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. Thus every time before piercing, system would display following options.
3.8.1Pierceoncurrentposition
Systemstartspiercing,usuallyoninternalholes.
3.8.2Chooseedgepiercing
1）Userscouldpress【↑】【 ↓】【 ←】【 →】button，move torch to the sheet edge, starts pre-heating.
2）Press 【START】button after pre-heat ends. Torch moves linear distance at pre-set speed
to the piercing position, resumes cutting.
