The air jet orifice of the torch head clamp needs to be located underneath the electrode and facing towards the work end
of the electrode with the air jet between the electrode and work piece. To avoid damage to the torch head a minimum ex -
tension of the electrode should be no less than 45mm. Air pressure should range between 80 psi and 100 psi at the torch
and the air supply hose requires and internal diameter of no less than 6.5mm.
Single-phase machines with low open-circuit voltage are not suitable for air carbon arc gouging. Most three-phase weld -
ing power sources of sufficient amperage output may be used for air arc gouging. The arc voltage required for air carbon
arc gouging and cutting ranges from 35 to 56 volts, therefore the open-circuit voltage needs to be at least 60 volts. For
most applications the carbon electrode is connected DC+ and the electrode should not extend more than 170mm from
the gouging torch otherwise the air jet becomes ineffectual in removing the molten material.
The air carbon arc process is flexible, efficient, and cost effective on practically any metal; carbon steel, stainless steel
and other ferrous alloys; as well as cast iron, aluminium, nickel, copper alloys and other non-ferrous metals. It has found
many uses in industry today from metal fabrication, casting finishing, chemical and petroleum industry, construction, min -
ing, general repair and maintenance.
