1
st
cycle
• Press the torch trigger 1
• The gas pre-flow time
expires (shielding gas flows).
• The arc is ignited (HF ignition).
• The start current
flows as long as the torch trigger is held, but at least for the start time
(the
HF ignition shuts down).
2
nd
cycle
• Release torch trigger 1.
• The welding current increases in the up-slope time
to the main current
.
During the main current phase, you can switch to the secondary current
in two ways: Either tap torch
trigger 1 or press and hold torch trigger 2. Lowering to the secondary current
takes place using the
slope time
.
By tapping torch trigger 1 again or releasing torch button 2, the welding current increases with the slope
time
back to the main current
. The slope times
and
are set in the Expert
menu
> see 5.2.9 chapter
).
3
rd
cycle
• Press torch trigger 1.
• The main current
drops during the down-slope time
to the end current
.
