Gouging can remove welding seams and achieve a controlled gouge
profile. The gouge profile can be influenced by the actions in the following
table:
1 Hold the cutting torch at an angle to
the workpiece with a max. distance of
3 mm from the nozzle to the
workpiece.
2 Press the torch trigger to ignite the
arc.
3 Turn the cutting torch slowly in a
vertical direction.
4 Hold the cutting torch until the arc
emerges from the underside of the
workpiece. Only then is the hole
completely pierced through.

direction. Sparks must emerge from
the underside of the workpiece.
