Setting the welding output
• A variable welding output allows seam thickness and pre-heating times to be
coordinated.
• 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)
).
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.
Fine tuning during the welding proces
• By turning the
potentiometer (3)
, the welding output set can
be reduced from the maximum value (e.g. 85) to the minimum
(displayed on the
(22) display bars
).
• The plastizised material throughput is also dependent on the
welding rod thickness used. If the welding output is too high
with the output display “30” and the potentiometer is set to
“minimum”, the next smallest welding rod thickness must be
selected.
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.
