Q ) When SteelTailor portable CNC cutting machines is in oxygas cutting process when lose fire (heating) press Stop for machine to stop then press  Backward (or  Forward) in order to continue cutting then when press  Start for cutting, the machine start immediately without repeating the heating and oxygene discharge process  in order to piercing and the height sensing control donot work (we have to up/down torch by manual ).

(A) once the Flame has been cut or the pause key (RED key) has been pressed you have to press either CUTOXY or PIERCE keys to start cutting again.

Q)     When cut a program with many figures then when the cutting process starts ,but the portable CNC cutting machine has to run the test mode.
A). In the AUTO mode you can set the TEST run, once the test run is selected the portable CNC cutter will make the X and Y axis movements according to the shape. The Flame or Plasma cutting will not be started.
In AUTO mode press “X” key in the keypad to activate or deactivate the TEST run function.

Q)   I have had one other machine that has had some issue with Legend B5II table plasma cutting machine it was waiting for green button every cycle and they had the WENTAI on, they turned this if and now it will not arc until they press green button each cycle can you give me some help with this question please.

A) Set GG3 code to set the machine to factory set parameters
How to set GG3 Code?
A.      Power ON the machine
B.      When main screen appear press “GG3” (That is Alphabet “G” two times and number”3” one time)
C.      A three option window will come
·         PARAMETER :-select this is you want to set the parameters values of the CNC to the factory set values.
·         FORMAT:- To remove (format) all the saved contents on the CNC machine.
·         Chinese :- To change the language used in the controller menus.

Q:Can Hypertherm´s ArcWriter adapted to a Dragon or Legend plasma cutting machine?

A:There shouldn’t be any problem in connecting the machine with the CNC machine. The only thing that concern us is if the THC holder is correct size to fix the ARC write torch directly you may have do some modification.
The Torch diameter of Arc right is 3.81 cm

The torch diameter of usual air plasma machine is 2.5 cm.
Please contact the after sales team for the plasma ARC Write manual and the connection details.

Q:The price of SteelTailor THC is more than 1000 dollors,and other supplier’s only 3-400 dollors,Why so much different?

A:SteelTailor  Arc voltage sensing THC is specially designed for SteelTailor CNC cutting machines.

After so many years of rigorous testing and constantly updated matches by SteelTailor,The quality is very high.The function is multiple .On this basis we have developed arc voltage and capacity THC .It is an THC both for Flame and Plasma automatic sensing.The THC of SteelTailor is is competitive price and more better than THC valued 3-400dollors.

Q)  The CNC controller is showing STOP warning in the controller AUTO mode.

A) Please check if the EMG switch is kept pressed. If EMG switch is pressed this could happen.
If the EMG switch is pressed when power ON and released when power OFF, After that if power ON the machine this error will come. To resolve the issue Power off the machine then press the EMG switch and then power ON the machine and go to AUTO then release the EMG switch to solve the issue.

Q:Starting operations of SteelTailor machine with Plasma cutting
A:(1)  Set up the six wire connections between the plasma and the CNC machine as per the manual.

Connection J27 & J28 are inside the plasma machine. You need to open the plasma power source to give this connection.
Caution: The J27 and J28 is very high voltage pin 50 ~ 300 VDC while working so give good insulation for the connector. 
(2)  Place the correct parts to the Plasma torch make sure the parts you put as per the plasma machine user manual. Check if these part are with you or check the manual for alternative parts 

(3)   Set the plasma to any one of the mode, the second option recommended consumable life.


(5)  Turn on the plasma machine set plasma Amps (output current) to 105 amps set the cutting speed according to the chart in the CNC machine or program. Refer the CNC manual for speed setting.

(6)  How to change plasma cutting machine cutting speed?
(a)  First set the maximum cutting speed in SETUP [F4]----SPEED[F1]----MACHINING SPEED set the value is mm/min in metric mode or inch/min in inch mode
(b) The value set in the MACHINING SPEED is the maximum speed at which the machine will move while cutting
(c)  In AUTO mode the cutting speed can be adjusted while cutting operation by pressing 

User can increase speed to a maximum value set in SETUP[F4]----SPEED[F1]----MACHINING SPEED 
(d)  In AUTO mode before the cutting operation or while the cutting is paused a desired cutting speed can be entered by pressing F key on the controller. You can enter the desired cutting speed (Value should be set between 05 ~ MACHINING SPEED) after entering the value Press ENTER key.
(7)  After setting the speed Make sure the CNC is in plasma mode  and Pierce time
SETUP [F4] --- CTRL [F5] --- PLASMA/FLAME (1/0) set 1 for plasma.
SETUP [F4] --- PLASMA [F4] ---PIERCE TIME 0~12 (This time depend on the thickness of the material)
(8)  Also set the THC according to the THC manual.
(9)  After setting all this select a drawing from the LIB press ENTER and then APPLY to set the dimensions.
(10)   Go to AUTO mode press Green button now the CNC should start cutting process.
(11)  Cutting process:-The THC first comes down and touches the plate and moves up to a height set by you in the THC. At that point the plasma flame will get ignited and start to make a hole (Pierce) in the plate the torch wait till the pierce time is over (set in the CNC controller). The pierce time is over the CNC start moving and cut the desired shape on the plate.
