Tips


・No user's material is found in the material setting

　

Materials that can be coditioned are iron , copper , tungsten , carbon

and NAK.

Please choose the "Iron"setting, for Titanium, Nickel, Tin.

Please choose the "Aluminum"setting for Magnesium.



・In case of processing the thin material


The minimum setting of thickness is up to 5mm.

Please keep in mind the following notes

in case of processing less than 5mm thickness.

　　 ①Close the high-pressure jet adjustment valves.　　　　　　　　　　　　　　　　　　　　　                                                                                　　


　  ②Lower the processing power by changing the conditions

　　　　Please contact with Technical Expert Division

      for any changes inconditions.


・In case of changing the procrssing conditions

to avoid the frequent breaking of wires


The breaking of wire occurs, when it reaches high temperature locally.

In order to enhance the cooling effect by jet flow, it is effective to keep a

distance from the wire to the material and to discharge the material sludges.As it is possible to adjust the electric discharge to the appropriate time,

to the change the servo reference voltage, or the table feed speed.

Please contact with Tecnical Expert Division.


・In case of inputting the created DXF data on AG30L


It is possible. Please contact with Technical Expert Division.

The exclusive USB shoud be used for inputting data.


・Effective confirmation with disconnection measures


Please confirm the following,
　　①Full open the high-pressure jet adjustment valve.　　　　　　　　　　　　　　　　　　　　                                          
　②Set the EPA VAlue　-4　
　　　　　　　　　　　　　　　　　　   　

・Automatic wire threading does not work.


Please contact with Technical Expert Divison
This trouble needs cleaning,exchanging parts ,etc. to be solved.

・Wire is running out.


Exchange the empty bobbin to the wire's.

If you need help, please contact with Technial Expert Division


(Reference) Here is a video of how to connect wires.










・Water is flowed out,when the tank is opened before finishing


Please wipe away the water towels , etc.

If the water is flowing into the machine, it causes the breakdowans.

Please contact with Tecnical Expert Division immediately.


・The water-level is rising.


It may be that the sensor of water-leve is not working.

If the sensor rises, the water does not flow out of the tank.

Please contact with Tecnical Expert Division.


・Abnormal sounds happen while wire threading.


It may happen from the feed roller.

Because of loose attachment ,the reattachment shoud solve this problem.

Please contact with technical Expert Division.

　　　　　　　　　　　


・Wire is tangled up at the wire-discharging part of the back of machine


Do not keep processing with the tangled wire.

It can be taken off by hand, but sometimes it may need disassemble

the wire-dischraging parts.
