ARC melting shot spraying is the use of two continuous conveying wire as consumable electrode , arc that between two pieces of conductive wire used as a heat source to melt itself,and then send the molten metal atomization to the product surface with high speed to form a coating .

To preserve arc stability burning in the two ends of wire , on the one hand you need to plus the the airflow then make the molten metal away from the end of metal , on the other hand need to establishing the appropriate balance with arc voltage ,arc current and wire speed.

Compare	Front-pull wire feed	Push-back wire feed
Features	Wire feeding power on the gun body	Wire feeding power separate from the gun body
Advantages	1. Compact structure； 2. Wire Feed stability, good atomization effect; 3. Spray gun can be far from power, operating flexibility	Gun basically responsible for the atomizing function, the structure is relatively simple, relatively light weight
Shortcoming	1. After the gun is connected with the overall weight of the trachea and the cable is relatively heavier, hard to operate; 2. Transmitting power is relatively small	1. Due to the Wire feeding power back, short distance between wire feeder and gun, generally not more than 2 metres, job is not flexible, suitable for large flat workpieces operation; 2. Not suitable for using a soft wire
