DC Round Air gouging carbon rod(6*355mm)
Carbon rod is non-metal product as a kind of essential consumables before welding in the carbon arc gouging crafts which is made of carbon, graphite and proper adhesive through extrusion moulding and copper plating with 2200℃ baking . High-temperature resistance, excellent conductivity and unbreakable characteristic is suitable to cut metal into required shape.
Gouging Carbon Rods have a wide use on shipbuilding, boiler pressure vessel makeing, casting, steel, storage cell in light mechanic and chemical making. It also be used to remove defective welds.
Flat arc air gouging carbon electrode rod Advatanges:
a. Excellent arc stability.
b. Improve the production efficiency and the working condition of workers.
c. Good at processing the weld groove, especially U type groove.
d. Convenience operation.
e. Deduct lacuna of unqualified welding line and repair it.
f. Many metals can be processed, such as cast iron, stainless steel, copper and iron.
g. Simple equipment, safe for operation. Only need one set direct current electric welding machine, compressed airflow, specialized gouging carbon arc rod.
NOTE for using of Flat arc air gouging carbon electrode rod:
1. Carbon rods must be kept dry, moisture must be dried before use.
2. When DC power supply,the carbon rod connected to the positive, negative connected work.
3.The compressed air pressure to maintain 0.5-1.6MPa.
4.Carbon rod and the arc between the work piece about 3mm, carbon rod exposed fixture is about 100mm.
5. Carbon rod and the workpiece into a 45 ° angle, and along the tangent (or straight) direction of the planing.
6.Carbon rods must be well ventilated.
