Why Powder Coating Gun Prices Vary
Powder Coating Gun Settings Understanding
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.
Such an indicator demonstrates the capacity of charge that moves from the unit’s electrode to the air cloud and later on the substrate of the part being dabbed. Pay attention that setting the µA range between 20 and 25 can help cope with the complex areas coating and if the surface isn’t that compound, the index can be lower.
The specified coating guns usually have the automatic powder output equipoise system that controls the airflow. The chosen number demonstrates the supreme percentage of powder for further usage. For example, 70% is the highest guide-mark, but if you want to work with the small details, it’s better to choose the lower adjustment.
My name is Brandon, and I’ve been interested in cars since I was a kid. I got a bachelor’s degree in Automotive Technology and worked in a private car workshop. I have two cars that have been completely upgraded with my own hands. So I successfully put all my knowledge into practice.
