Squeeze The time interval in a weld sequence for the electrodes to exert full welding
force on the work piece.
Squeeze time The time allowed for the welding electrodes to build up full pressure on the
components to be welded. Expressed in mains cycles.
Start signal The signal that starts the weld sequence.
Stepper A program of parameters required for stepping.
Stepping A technique of progressively increasing the weld current over the course of a
large number of welds in order to compensate for the effects of electrode
wear.
Thermostat A switch device that operates at a certain temperature.
Tip dress
acknowledge
An input to acknowledge that the electrodes have been dressed.
Tip dress request An output to indicate that the electrodes require dressing.
Tip dressing Filing or machining worn electrodes to restore their original shape and
dimensions.
Toroid A device used for sensing current in a cable. The current carrying cable must
pass through the toroid.
Upslope A linear increase in current from an initial value to the Main heat value.
Upslope time Time taken for current to increase from an initial value to the Main heat value.
Expressed in mains cycles.
VA Volt amp
WAV See Weld air valve.
Weld air valve Electrically controlled valve for admitting air to the air cylinder responsible for
forcing the weld electrodes together.
Weld current High current passed from one electrode to the other, through the
components being welded. The current must be large enough to generate
sufficient heat to melt the metal and produce a weld.
Weld transformer Electrical component for converting mains voltage input to low voltage, high
current output.
