Gouging Rods/Gouging Carbons

In the air carbon arc process, gouging carbons consist of carbon rods coated with copper for cutting, gouging, and removing weld defects.

The 305mm long pointed carbon gouging rods  are available in diameters of 4,5, 6.4, 8, 10 and 12.7mm.

The electrode diameter should be selected according to the depth and width of the project.

Sizes 4mm- 10mm – boxes of 100 rods.  12.7mm box of 50 rods.

These gouging carbons are designed especially for the carbon-arc metal removal process, which melts metal with an electric arc and then blows it away with a jet of compressed air. These carbons contain a precisely formulated blend of carbon and graphite that produces the most efficient metal removal performance.

What is Carbon Arc Gouging?

Air carbon arc gouging works as follows. An electric arc is generated between the tip of a carbon electrode and the workpiece. The metal becomes molten and a high velocity air jet streams down the electrode to blow it away, thus leaving a clean groove.

The process is simple to apply (using the same equipment as MMA welding), has a high metal removal rate, and gouge profile can be closely controlled.

Disadvantages are that the air jet causes the molten metal to be ejected over quite a large distance and, because of high currents (up to 2000A) and high air pressures (80 to 100 psi), it can be very noisy.
