GOUGING ("GOUGE" operating mode)

GOUGE
MILD STEEL
Air 5�5 bar
To run gouging operations, which is only available for the hand torch, select this mode.
For the material, gas and cutting current settings, as well as for the adjustment of the working pressure refer to par-
agraph 4.1.
This operation makes it possible to remove defective welds, separate welded pieces, prepare edges, etc. For this
operation use the appropriate nozzle.
The current value to be used varies from 50 A 70 A for torch CP70C and from 60 A to 130 A for torch CP162C depend-
ing on the thickness and quantity of material to be removed. With the welding torch in slanted position (fig. 6) proceed
towards the melted metal so that the gas coming out of the welding torch keeps it away.
The angle of the welding torch in relation to the workpiece depends on the penetration to be obtained. As melted
dross tends to stick to the nozzle holder and nozzle guard during this procedure, it is best to frequently clean them so
as to avoid double arc events which may destroy the nozzle in a matter of seconds.
Given the strong (infra-red and ultraviolet) radiation emission during this operation, it is recommended that the operator and people
in the vicinity wear adequate PPE.
