The 3710 plasma control system is the latest product of the compact control cabinet series of Plax Surface Technology. 3710 control cabinet meets CE standard. It has an auxiliary circuit that can control two powder feeders and can be used for workpiece cooling and other purposes. Like the products it inherits, it is also an economical plasma spraying control system applicable to factory production. Its easy-to-understand control and compact design make it an ideal choice for any plasma application.

"Critical microporous gas flow control"

The 3710 control cabinet uses a critical orifice flowmeter for flow control. Compared with the float flowmeter, the critical micropore flowmeter has higher accuracy. At the same time, the critical micro-pore flowmeter has no moving parts, so there is no problem that the flow accuracy of the float flowmeter will decrease with the increase of service time due to the wear of the glass tube. This makes it possible to obtain high-precision and repeatable gas control. Unlike the float flowmeter, the orifice flowmeter is not sensitive to the back pressure. Constant and reproducible gas parameters can ensure the quality and reproducibility of the coating.

The control cabinet has safety self-locking to prevent the spray gun from working in case of water, electricity and gas circuit failure. The control cabinet also integrates NFPA type "Z" purging and audio-visual alarm. The contactless power control makes it possible to preset the current before firing the gun and ensure that the current fluctuation range is within 1%.

Operation/process characteristics:

• Critical orifice gas flow control.
• Air supply pressure measurement.
• The built-in PC-100 power controller with digital display of voltage and current has the function of "soft arcing" and preset parameters.
• Contactless control.
• Two powder feeders can be controlled.
• Auxiliary power on/off control.

Safety features:

• The hydrogen control circuit part adopts an independent setting structure and has the functions of "purging" and audio-visual alarm.
• 24V DC "purge" circuit.
• The electrical control part is completely isolated from the gas control part.
• Remote emergency stop box.
• Stainless steel combustible gas pipeline.
• Safety interlock function.

Optional

Model 3621 voltage controller: designed to easily detect the spray gun voltage (measure the voltage at the spray gun) or the system voltage (measure at the input end of the high-frequency generator). Due to the degradation of water-cooled cables in use, their resistance increases and seriously affects the performance of the system. The 3621 remote control function enables the operator to switch between the system and the spray gun and display it on the power controller. In this way, it is very convenient to measure the pressure difference of the water-cooled cable and master its use status.
