Basic Characteristics RAPID

ArcC Arc welding with circular motion
ArcC1
ArcC2
Example
ArcC (Arc Circular) is used to weld along a circular path. The instruction controls and
monitors the entire welding process as follows:
- The tool centre point is moved in a circle to the specified destination position.
- All phases, such as the start and end phases, of the welding process are controlled.
- The welding process is monitored continuously.
The only difference between ArcC, ArcC1 and ArcC2 is that they are connected to different
process systems configured in the System Parameters. Although ArcC is used in
the examples, ArcC1 or ArcC2 could equally well be used.

This welds a circular seam between points p1 and p3 (via point p2) as illustrated
in Figure 1.

On the way to p1, preparations for the weld start, such as gas preflowing, are carried
out. The process and the actual weld movement then start at position p1 and end at p3.
The start and end processes are determined by seam1 and the welding process by
weld5. Weaving data is carried out according to noweave. (No weaving if the
weave_shape component value is zero.)
V100 specifies the speed attained during the flying start to p1.
