| APPLICATION |
| 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 |
1.Power: Normal
D.C. for welding machines can be used for air-arc
gouging carbon 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 the 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 pressure
is for bigger diameter of the rod and lower pressure
for smaller diameter. If air pressure is too high,
electric arc is unstable; if too low, melted metal
can not be blew off easily, which will influence
the quality of gouging groove.
