13.8 HC MAG functions
13.8.1 Adjustment of poling
Change poling by pressing the key „HC“:
OFF DC+ Plus pole on welding torch ,
minus pole on the workpiece
Continuous light DC- Minus pole on the welding torch,
plus pole on the workpiece
Flashing HC MAG procedure (AC)
The change to poling DC- and AC is only possible if:
•
HC MAG – module is available and properly connected
•
A special characteristic „HC MAG“ has been selected in mode „Synergic“,
or if alternatively the procedure „Norm“ has been selected
13.8.2 Adjustment of wire feed speed / energy
If
type of poling
DC+ and DC- has been selected, the following functions are active on the
rotary pushbutton (E):
By turning the rotary pushbutton (E), a wire feed speed [m/min] / energy value can be
selected as a default value.
Alternatively, the expected welding current or plate thickness can be set as default value by
pressing the pushbutton.
If a
HC MAG and
poling
AC have been selected, the following functions
are active on the rotary pushbutton (E):
By turning the rotary pushbutton (E) a wire feed speed [m/min] / energy value can be
selected as a default value.
By a long pressure on the rotary pushbutton (E), the display changes to the additional
selection voltage value [V] / arc length correction [%].
At weld end, the current value achieved during welding is displayed (welding
current „hold-value “). In order to display the pre-set values, press the rotary
