manual.
12. Display of welding current, wire feed speed or
material thickness.
13. Display of trim voltage, welding voltage or Arc
adjust
14. Setting welding current /
selecting welding programme
Turn the control knob to set the desired welding
current.
Short press (14A): Change between display of
welding current, wire feed speed or material
thickness.
Long press (14A): Select welding program.
15. Setting welding voltage, Arc adjust and
welding process
Turn the control knob to set the desired welding
voltage or Arc adjust.
Short press (15A): Change between display of
trim voltage, welding voltage, Arc adjust or seam
average (welding current/voltage).
Long press (15A): Opens for setting the welding
process.
16. Selecting sequences
Allows the operator up to nine sets of all
adjustable values.
Short press: Changes to next sequence.
Long press: Opens for selecting number of
sequences. Turn (15) to choose number.
The function is off when 0 is chosen. Press (15A)
briefly to accept choice.
17. Tack welding
When this function is activated, sequence,
hotstart and slope down are off.
18. DUO Plus™
Pulsating wire in connection with synergic MIG
on/off.
19. Pulse welding (only Synergic Pulse Box)
MIG pulse welding on/off.
20. Selecting trigger mode
Change between 2-stroke (indicator off) and 4-
stroke (indicator on).
2-stroke: The welding process starts when the
torch trigger is activated and ends when the torch
