When joining pressure is reached, the program automatically goes to the joining process and
the t4 timer starts.
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).
Attention: Hold down the Release button (10) and the Close machine button (11) until the
joining pressure is reached. Then the hydraulic unit shuts off and the buttons can be released.
The pressure is monitored and automatically regulated again. If the hydraulic system repumps
too often (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

 Dissipate the pressure completely by pressing the button (3).
