•
VoltageRms
The RMS voltage in a halfcycle, or average RMS voltage for a segment or weld.
•
VoltagePeak
The peak (positive or negative) voltage in a halfcycle, or the peak voltage in a segment or weld.
•
Force
The average force at the electrode tips during the halfcycle, segment or weld (average of Pre, Weld
and Post segment half cycles).
•
Set Down
Set Down is the decrease in thickness as a part is welded (relative to initial thickness).
Halfcycle: Set Down is the lowest thickness during the halfcycle minus the Initial Thickness value
at the beginning of the weld (halfcycle 0 from segment 1).
Segment: Set Down for a segment is lowest Set Down reported for a halfcycle within the segment.
Weld: Set Down is the difference between the initial thickness at the beginning of the weld
segment (halfcycle 0 from segment 1) and the Final Thickness at the end of the Post segment.
•
Expansion
Expansion is the increase in thickness as a part is welded (relative to initial thickness).
Halfcycle: Expansion is the highest thickness during the halfcycle minus from the Initial Thickness
value at the beginning of the weld (halfcycle 0 from segment 1).
Segment: Expansion for a segment is the highest Expansion value for a halfcycle within the
segment.
Weld: Expansion is the highest Expansion value from all of the segments (excludes PRE).
•
Initial Thickness
The thickness of the workpiece at the start of a halfcycle, segment or weld (Initial Thickness from
the first halfcycle in segment 1, the first weld segment).
•
Final Thickness
The thickness of the workpiece at the end of a halfcycle, segment or weld (final thickness from the
POST segment).
•
CondAngle (Conduction angle)
A measure in degrees of how long the weld timer SCR's were turned on, allowing current flow
during a halfcycle. The average conduction angle for a segment or weld.
•
Resistance (dynamic)
The calculated dynamic resistance of the workpiece during the halfcycle, equal to Voltage RMS
divided by Current RMS. The average resistance for a segment or weld.
