Surprecision Arc-air Gouging Carbon Rods 0.2" x 13.98", Round Copper Coated Gouging Carbon Electrodes Diameter 5mm, Length 355mm(Package: 20pcs)

【SPECIFICATIONS】Diameter 0.2"/5mm; Length 13.98"/355mm; Package 20pcs. 【Material】Contains a precisely formulated blend of carbon and graphite, 80% graphite and 20% copper, using a 72-hour electroplating process with a thick coating. 【High Quality】High temperature resistance, easy to conduct electricity, high welding efficiency. 【Round Carbon Rod】Mainly used for root cleaning of welds, back grooving and removal of welding defects, etc. 【Application】It is widely used in foundry, boiler, shipbuilding, chemical industry and other industries to plan low carbon steel, cast steel, stainless steel, copper and other metals. Instructions for Use:
1. The carbon rod must be kept dry, and it can only be used after being dried when wet.
2. When used in DC power supply, the carbon rod is connected to the positive pole of the power supply, and the workpiece is connected to the negative pole.
3. The compressed air pressure should be kept at 0.5-1.6MPa.
4. The arc distance between the carbon rod and the workpiece is about 3mm, and the exposure of the carbon rod to the fixture is about 100mm.
5. The carbon rod forms an angle of 45° with the workpiece, and is planed along the tangent (or straight) direction.
6. The carbon rod must be well ventilated when using it and operate according to the working current.
