Setting the welding output
A variable welding output allows seam thickness and pre-heating times to be coordi-
nated.
Presetting on the display
• Set the cursor to the «SPEED» position by pressing the
Select key (28).
• Define the maximum welding output value (30 to 100) with the
Up (29)
or
Down
(27)
keys
Fine tuning during the welding process
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
display bars (22).
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 potentio-
meter is set to “minimum”, the next smallest welding rod thickness must be selected.
Setting parameters in the operating window
The
cursor (31)
shows which parameters can be set. After switching on, the cursor
is on the
«SPEED»
position.
In the operating window, the following parameters can be selected with the
Select
key (28)
and changed in their values with the
Up (29)
and
Down keys (27).
