Welding preparation
Setting the output volume
The output volume and the pre-heating time can be coordinated with
each other according to the type of seam.
• Presetting on the display
– Move the cursor to the «SPEED» position by pressing the Select key (28).
– Specify the maximum output value (30-100 %) using the Up (29)
or Down (27) keys (displayed on the drive display bars (22)).
• Precise adjustment during the welding process
– The output volume can be reduced from the maximum set value
(e.g. 85%) to the minimum by turning the potentiometer (3).
The output volume is dependent on the size of filler rod used. If the output
is too large when the output display is set to «30» and the potentiometer
to «Minimum», the filler rod must be changed to the next size down.
Setting the PLAST and AIR temperatures
• Move the cursor to the «PLAST» or «AIR» position by
pressing the Select key (28).
• Set the temperature value by using the Up (29) or
Down (27) key.
Monitoring the welding parameters
The actual and ideal values of the AIR and PLAST temperatures are constantly monitored. If an actual value deviates
from the relevant ideal value (value is outside the range of tolerance), this will be indicated by a change in status on
the status display (30). If necessary, the drive motor will be temporarily disabled until the welding parameters are
back in the specified tolerance range. The possible status display and the ranges of tolerance are shown in the
following graphic and table.
