Work Environment Requirements
Welding performance may not meet technique standards without the following conditions.Welding performance may not meet technique standards without the following conditions.
|CNC Plasma cutting torch: Used by machine or robotic cutting||Handheld Plasma cutting torch: Used for manual cutting by hand|
LGK Plasma Cutter machine is optimized for machine / robotic plasma cutting but can also be used for manual cutting. If you order a CNC portable plasma cutter from our shop with the LGK plasma cutter, then you will get CNC machine cutting torch without additional charge.
NOTE: When ordering LGK plasma cutter, please specify which type of plasma torch you want to be delivered with your plasma cutter! Usually it is delivered with a manual cutting torch. If you ordered a portable CNC cutter , then in this case the appropriate machine CNC torch comes by default with no extra charge.
The control circuit of this cutting machine adopts advanced electronic part IGBT as the main inverter switch component. Three-phase AC power is converted to 20KHz high-frequency DC current after being rectified by three phase rectifier. Then under the function of IGBT inverter the DC current is inverted to AC high frequency current, which is inverted to DC current after experiencing voltage reduction in high frequency transformer, current rectifying in fast recovery diode. This DC current is filtered through reactor, and the output cutting current is obtained. Control circuit can control output current by controlling driven pulse width. The real time cutting current, which is obtained through current sensor connected to output terminal in series, is used as negative feedback control signal. After comparing with current adjusting signal, the negative control signal is sent to PWM adjusting integrated circuit, then a controlled driving pulse is output to control IGBT. Thereby a constant output current can be maintained, and a steep dropping & constant current external characteristic is obtained. Striking arc adopts high-frequency striking model. The main circuit refers to appendix figure, and principle diagram of control circuit is shown as below figure.
