Equipment: high-power secondary atomization arc spraying machine is set wire feed, power, gas in one simple operation of the equipment, safety, low failure rate. Good combination spray coating and the substrate, the power output is positive, negative direct current to two metal wire (current up to 600A, voltage 24-45V), the conductive parts of the electrical conductivity, atomizing spray gun reliable conduction uniform and fine particles. The stable arc spraying, no broken arc, shelling and other phenomena.
