 Set the pressure so that the ends of the work pieces can again be lain uniformly and nearly
pressure-free onto the heating element.
A signal sounds shortly before the end of the warm-up time.
 At the end of the warm-up period, the work pieces move apart, the heating element SA must
be removed, or the heating element VA is automatically swung out and the work piece ends
move together.
The pressure is linearly raised to the appropriate joining pressure.
When joining pressure is reached, the program automatically goes to the joining process and the
t4 timer starts.
The pressure is automatically monitored and regulated. If the hydraulic system repumps too of-
ten (meaning there is high pressure loss), have it checked.
 Put the heating element back in the storage case.
 The welding process is ended after the cooling down time has expired, is stored, a signal
sounds and the pressure is dissipated automatically.
The upper progress bar shows whether the pressure lies within the
correct range (green) or within a permissible (yellow) tolerance range
or whether it lies outside (red) the tolerance range. The time lapse is
shown below. The actual pressure is shown in display (2) and the
remaining joining time in display (9).
