Carbon Arc Cutting Air (CAC-A). How does it work?
Arc cutting and gouging process. Jet of compressed air passing through electrode holder and its head blows away molten metal
What position and metals can it b used for?
For all positions on any metal that will conduct electricity, such add carbon-steel, stainless steel, cast iron, and copier (and their alloys).
Main use?
To gouge weld grooves, back gouge welds, gouge out defective welds, and to prep cracks for Welding. Can also be used for washing and beveling
R the currents used on CACA same as what you would used for stick rods?
No, much higher.
Connecting cable of CAC-A torch contains:?
Both electrical cable and compressed air hose.
Use AC or DC constant current Welding machine?
Either for power supply, but DC is preferred.
