MACHINE SEQUENCES & DEFINITIONS:

SQUEEZE TIME:

The time interval between the initial application of the electrode force on the work and the first application of current. Note that this is the process definition. The control definition is the time interval between sequence initiation and beginning of weld current. Squeeze time is necessary to delay the weld current until electrode force has built up to the desired level.

SQUEEZE DELAY:

Is used on a repeat operation, additional time is added to Squeeze on the first weld only.

WELD TIME:

Is the time during which welding current is applied to the work in making a weld. It is measured in cycles of line voltage as are all timing functions. One cycle is 1/60 of a second in a 60 Hz power system.

IMPULSE:

Amount of weld pulses.

COOL TIME:

Time between successive heat impulses.

HEAT TIME:

The time duration that welding current flows in one impulse.

HOLD TIME:

The time during which electrode force is maintained on the work after the last impulse of welding current ceases. Hold time is necessary to allow the weld nugget to solidify before releasing the welded parts.

OFF TIME:home

In the Repeat mode, the time duration between Hold count and Squeeze count to allow the work to be repositioned
