(2)
HOLD indicator
every time you finish a welding operation, the actual values for welding current
and welding voltage are stored, and the “Hold” indicator lights up.
(3)
Digital display m/min - mm - A
function differs depending on whether it is in the manual or program mode
Manual mode
-
Wirefeed speed (m/min) ... displays the set wirefeed speed
-
Sheet thickness (mm) ... no function
-
Welding current (A) ... displays welding current actual/hold value
Program mode
-
Wirefeed speed (m/min) ... displays the set wirefeed speed
-
Sheet thickness (mm) ... guideline for the material strength of the base metal
-
Welding current (A) ... welding current command/actual/hold value
(4)
Selector switch digital indicator
for selecting and displaying the desired function on the digital display
Wirefeed speed (command value)
Sheet thickness (guideline)
Welding current (command/actual value)
(5)
Intermediate arc indicator
between the dip-transfer arc and the spray arc, a spatter-prone “intermediate arc”
occurs. In program mode, this is signalled by the the intermediate arc indicator
lighting up. By changing the wire diameter or choosing a different shielding gas
mix, the intermediate arc can be bypassed and optimum welding results achieved.
(6)
Welding program selector switch
for selecting the desired welding program depending on shielding gas and filler
metal

DIN designation / welding wire alloy
Manual mode
... the wirefeed speed is adapted to the welding
voltage using the wirefeed speed adjuster (scale = m/min)
Composition of shielding gas and amount of individual
components in %
On the „CO
2
“ series, these programs are
fixed to pure CO
2
, not mixed gases
Important!
In the case of additional wire and/or shielding gases that differ slightly from the
set values, corrections can be carried out using the wirefeed speed adjuster (scale = %).
