APPLICATION INFO
> Highly efficient metal removal, defect & crack repairs, weld removel, edge preparation, etc
> Use with gouging carbon rods + DC power source + compressed air
> Use with 5mm - 13mm gouging carbons
> Requires DC Power Source with minimum 300 Amps output

HOW IT WORKS
> Air arc gouging process is similar to arc/stick welding, in some respects. The gouging torch/handpiece holds a gouging carbon rod, like a stick welding electrode holder.
> The carbon rod creates an arc when in contact with the metal workpiece and is consumed during gouging
> The torch is connected to a welding machine / power source and to compressed air supply
> When the air valve on handpiece is opened, this forces air down through a copper jaw/nozzle, and down one side of the carbon rod
> The operator drags the carbon rod across the job, this creates molten metal in the "arc zone" which is then pushed away by the air jet
> Gouging carbons are available in different sizes, the choice of size will depend on the capacity of the welder / power source and/or the volume/thickness of metal to be removed

TYPICAL SET UP
Following is a commonly-used configuration. Note this can vary depending on the welder/power source and user preferences.
Power Cable/ Connections:
> Short length of welding cable made up, with cable lug on one end and male cable joiner/connector on the other
> This short cable is bolted onto the lug on the end of gouging torch cable, other end is connected/joined to a longer cable
> Longer cable is connected back to the welding machine / power source
> Cable size will depend on: amperage capacity required, welding or power source capacity, and/or gouging carbon rod size used. As minimum amps required for gouging are around 300A, cable size used is typically at least 35mm2 or 50mm2
Air Hose / Connections:
> Short length of 10mm ID air hose made up, one end crimped onto air fitting/nipple on gouging torch cable & other end fitted with male air fitting (eg nitto style, or user preference)
> Short air hose is then connected to longer air supply hose from air compressor
