1. Built-in high voltage module. The extremely high pressure part is only in the front section of the spray gun, which effectively protects the safety of the human body, reduces the electrostatic diffusion range, improves the utilization rate, and effectively improves the powder rate. 2, with cleaning gas, can effectively remove the powder on the needle. 3, in the corner position and groove position easy to spray, surround atomization effect is good, uniform powder, stable performance. 4, the controller adopts imported lines, which can automatically close the high voltage output when the spray gun is short circuit. 5, in the selection of different powder or different workpiece spraying, current and voltage conversion mode can be used to adjust the appropriate spraying current. 6, the controller can detect and display the output high voltage in real time. 7, the electric bin and gas bin independent design, so that dust can not enter the electric bin, effectively keep the circuit stable work. 8, this product is widely used in: hardware, electrical appliances, electronics, furniture
