What equipment is needed for arc carbon gouging?

Required equipment includes an air compressor, welding power source, carbon electrode and a gouging torch. The air carbon arc process is shown in figure 10-75.

How much air do you need to arc gouge?

A minimum extension of 2″ should be used to prevent damage to the torch parts. Normal compressed air pressures for CAC-A range between 80 psi and 100 psi at the torch; higher pressures may be used, but they don’t remove metal more efficiently. Use 60 psi (413.7 kPa) with the light-duty manual torch.

Can you arc gouge without air?

ZENA NO-Gas arc cutting/gouging rods let you gouge, bevel, and cut metal without needing a 300+ Amp air-arc gouging/cutting rig or an acetylene cutting torch and bulky gas bottles.

When was arc gouging invented?

1949
THE INVENTOR OF ARC GOUGING AND EXOTHERMIC CUTTING. Arcair invented arc gouging in 1949, and we’ve been the leading name in metal removal and cutting ever since.

What are the electrodes used in air carbon arc cutting made of?

The most widely used electrodes are DC copper-coated electrodes that are formed by combining the carbon-graphite mixture with a binder. These electrodes have groove uniformity, stable arc characteristics, and prolonged service life.

How do you hook up an air arc?

How many CFM do I need for arc gouging?

12-15 cfm will work but will work the compressor full time. The bigger the compressor and the more tank you have the longer it will last and more efficiently it will work. Most work can be accomplished without opening the air all the way on the torch.

How do you set up an air arc welder?

Can you arc gouge cast iron?

Application. As air carbon arc gouging does not rely on oxidation it can be applied to a wide range of metals. DC (electrode positive) is normally preferred for steel and stainless steel but AC is more effective for cast iron, copper and nickel alloys.

Can you air arc stainless steel?

The air carbon-arc process does not require oxidation to maintain the cut, so it can gouge or cut metals that the OFC process cannot. Most common metals (e.g., carbon steel, stainless steel, many copper alloys and cast irons) can be cut using the air carbon-arc process.

Can you air arc gouge aluminum?

This process is useful for cutting a variety of materials, but it is most often used for cutting and gouging aluminum, copper, iron, magnesium, and carbon and stainless steel. Because the metal is blown away by the air jet, it does not need to be oxidized.

What does CAC A stand for?

A carbon arc cutting process that uses an arc to melt metal which is blown away by a high-velocity jet of compressed air. The electrodes are rods made from a mixture of graphite and carbon, and most are coated with a layer of copper to increase their current-carrying capacity.
