Its aligning allows changing the magnitude of voltage that feeds off the powder fractions as it goes through the handheld compressor. The charge’s strength depends on the setting’s highness. The high ones are well for plane panels and complex details. Such settings are also able to improve the charge-transfer efficiency and influence on the distance amid the gun and the detail increasing. Consequently, it’s possible to get really uniform coverage on smooth surfaces. Sometimes, extremely high kV options can spark some tiny spots in the finish. Low kV settings are essential for Faraday cage areas and while cooperating with some special powders (ex. metallic). Almost every professional handheld powder compressor is usually complemented with an utmost voltage setting of 100 kV. Despite all the pros, the kV setting is limited to the power supply.
