Annex
Slope
Current increase (or decrease) from an initial to a final current.
Solenoid
Activates the cylinders to close the electrodes.
valve
SQZ
Squeeze time that elapses before the weld time. The electrodes squeeze the parts to be
welded together.
Stepper
Current (heat) stepping for compensating for electrode wear
Temp
Temperature
UST
Upslope Time; time during which the Current (HEAT) stops after beginning of 2.WLD
WC
Weld Complete contact: signal is output when the spot has been completed
WLD
Weld time
WT
Weld timer, also called resistance weld timer
