Fronius TransCut 300 Operating Instructions/Spare Parts List page 22

Hole punching Hole punching is necessary when a piece is to be cut out of a workpiece but the cut is
not started across the edge of the workpiece.
Important! Hole punching considerably reduces the service life of wearing parts. The tip
of the cutting torch should never touch the workpiece. In the case of thicker sheet metals
it is advisable to drill rather than punch a hole in the workpiece.
In order to protect the wearing parts, the cutting torch should be aligned at an angle to
the workpiece and at a distance of 1-2 mm from it. Once it has been lit, swivel the torch
slowly into an upright position until the arc has cut though the workpiece.
Making circular In order to cut a perfect geometric circle out of the workpiece, the guide set, which is
cuts available as an optional extra, must be used.
Before cutting, a hole should be drilled in the workpiece to start the cut. In the case of
thin sheet metals this can also be done by punching a hole. It is advisable not to fit the
guide set until after the hole has been punched, and to remove the spacer when cutting
with the guide set.
