(55) “Primary parameter” indicator lights
These lights show which primary parameter
is currently displayed in the multifunction
display (54).
(56) “Primary parameter” push-button
For switching between welding current,
material thickness, wire feed speed and arc
length, as indicated in the digital multifunction
display (54).
(57) “Downslope” push-button
Switches the downslope function on or off. A
lit LED next to the push-button indicates that
the downslope is on.
(58) “Arc length” control knob
To adjust the arc length in SmartGMAW,
PulseGMAW,
process,
OR
"Wire speed/Inductance" control knob. To
adjust the wire speed or Inductance in Manual
MIG process.
(59) “Arc length” LED indication
Indicates the degree of the trim in
SmartGMAW, Pulse MIG,
process.
OR
”Wire speed” LED indication Indicates the wire
speed in ManualGMAW process.
When the uppermost center LED is lit, the
programmed arc length/wire speed remains
unchanged; “0” is indicated in the
multifunction display (54). Turn the rotary
control knob (58) left to shorten the arc length/

are indicated during welding. After the welding
procedure, the “Hold” LED illuminates and the last
welding voltage and welding current values are
indicated. When the operator changes certain welding
adjustments (e. g. thickness, program, job), the
