KNOWLEDGE:

*Maximum of 7” stick-out
*Air jet should be on before striking the arc
*Air jet should be between the work surface & carbon electrode
*Air struck by bringing the electrode to work piece
*A short-arc should be maintained 35-36 volts

Technology performance:
Air-arc carbon rod gouging technology is mainly applied in the fields of metal structure, metal casting, and shipbuilding, etc,it enhances processing efficiency,and improves working condition by adopting the technique of air arc carbon gouging instead of the old pneumatic chiseling. The metal surface treated by carbon rod gouging is smooth clean and flat without ant harmful influence to the metal Performance. It is featured by convenient operation, low cost and noiselessness.

Attention to the usage of air-arc gouging carbon electrode:
1) Power: Normal D.C. for welding machines can be used for air-arc gouging car-bon electrode.
2) Range of currency: The currency range adopted directly influences the processing quality and results. if it is too small. it will be difficult for gouging; if too large ,it will cause heated carbon head too long, which will result in the rod becomes thinner and the processing quality poor. Therefore the proper currency range as shown in the table herewith should be adopted in accordance with the model and dimension of gouging carbon electrode.
3) Range of Air pressure: The normal air pressure range is 4- 6kg/cm2,which shall be in compliance with the diameter of gouging carbon electrode. In general, higher air pres-cure is for bigger diameter of the rod and lower pressure for smaller diameter. if air pressure for smaller diameter. If air pressure is too high, electrical arc is unstable; if too low, melted metal can not be blew off easily, which will influence the quality of gouging groove
