How much air do you 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.

What DC current is recommended for use with air carbon arc cutting?

The open-circuit voltage should be higher than the required arc voltage to allow for a voltage drop in the circuit. The arc voltage used in air carbon-arc gouging and cutting ranges from a low of 35V (volts) to a high of 56V; thus, the open-circuit voltage should be at least 60V.

How do I set up arc gouging?

Gouging is commenced by striking the electrode tip on to the workpiece surface to initiate the arc. Unlike manual metal arc (MMA) welding the electrode tip is not withdrawn to establish arc length. Molten metal directly under the electrode tip (arc) is immediately blown away by the air stream.

Can you air arc aluminum?

The air carbon arc process is inexpensive and efficient on all suitable metals. It is used for gouging and cutting magnesium, iron, copper, aluminum, and stainless and carbon steels.

Can you air arc 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.

What is the range of air pressure normally used for CAC A?

between 80 psi and 100 psi
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.

Are carbon arcs gouging?

Air carbon arc cutting, also referred to as metal arc gouging, and previously as air arc cutting, is an arc cutting process where metal is cut and melted by the heat of a carbon arc. Molten metal is then removed by a blast of air.

Can you air arc stainless steel?

The air carbon-arc gouging process does not require oxidation to maintain the cut, so it can gouge or cut metals that the oxyfuel process cannot. In fact, most common metals (carbon steel, stainless steel, high-alloy wear plate, copper alloys and cast irons) can be cut using air carbon-arc gouging.

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.

Can you gouge with AC welder?

Works with Common Metals: The air carbon arc process can be used for cutting or gouging most of the common metals.
