Workpiece thickness (unit: mm, -999.9 to 999.9)
Set the workpiece thickness to be welded.
The detected thickness can be automatically specified if the thickness
measuring mode is used.
2. THA=
Allowable ratio of workpiece thickness (unit: %, 0 to 100)
Set the allowable value to THA by the ratio over the thickness value
which is set to “TH”.
