DP 20 operating panel

 43

“Mode” push-button

 

For switching between the operation modes Normal, 
Pulse, TwinPulse and Electrode.

 44

“Material” push-button

 

For selection of the material to be welded. The push-but-
ton is also used for the “Decrementing” (-) function, e. g., 
to reduce the value of a secondary parameter.

 45

“TT Save” push-button (Tiptronic)

 

For storage of a job.

 46

“Welding wire diameter” push-button

 

For diameter selection of the wire to be welded. The 
push-button is also used for the “End” function, with 
which you can switch back to the display of the previous 
menu level.

 47

“TT Enter” push-button (Tiptronic)

 

For acknowledgement when saving a job.

 48

“Gas type” push-button

 

For selection of the gas to be used. The push-button is 
also used for the “increment” (+) function, e. g., to in-
crease the value of a secondary parameter.

 49

“Tiptronic” push-button

 

For switching the Tiptronic mode on or off.

 50

Multi-function display

 

For indication of all parameter values and messages.

 51

 and   push-buttons (Enter)

 

For switching between the individual secondary param-
eters. Pressing both push-buttons at the same time is 
used for acknowledgement (Enter).

 52

“2-stroke / 4-stroke” push-button

 

For switching between 2-stroke and 4-stroke operation 
mode. A lit LED indicates the currently selected operat-
ing mode.

 53

Rotary pulse encoder for welding current / material thick-
ness

 

The rotary pulse encoder is used for adjustment of the 
required welding current and material thickness. The ad-
justment range can be limited, depending on the select-
ed material-wire-gas combination.

 54

Digital multifunction display

 

For indication of the primary parameters such as welding 
current, material thickness (in mm), wire feed speed (in 
m/min) or arc length correction.

 55

“Primary parameter” LEDs

 

These show which primary parameter is currently indi-
cated in the multifunction display

 54

.

56

“Primary parameter” push-button

 

For switching between welding current, material thick-
ness, 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 / wire speed correction” rotary pulse encoder

 

For correction of the arc length or wire speed (depend-
ent on setting menu extra “arc lenght control“). Up to +/- 
40  % of the characteristic value can be corrected.

 59

“Arc length / wire speed correction” LED indication

 

Indicates the degree of the correction. When the upper-
most center LED is lit, the programmed arc length/wire 
speed remains unchanged; “0” is indicated in the multi-
function display

 54

. Turn the rotary pulse encoder

 58

 left 

to reduce the arc length/wire speed; turn the rotary pulse 
encoder

 58

 right to enlarge the arc length/wire speed

 

.

 60

Torch display

 

Indicates the current welding power, material thickness, 
wire feed speed or arc length correction (identical with 
the digital multifunction display

 54

). In Tiptronic mode, 

the current job set and the current job number are indi-
cated.

 61

Torch rocker

 

For changing the welding power, material thickness or 
arc length (depending on which value is being indicated 
in the digital multifunction display

 54

).

 

In Tiptronic mode, the rocker can be used to switch be-
tween the active jobs or job sets.

 62

Torch “Modus” push-button

 

Has the same function as the “Primary parameter” push-
button

 56

 on the DP20 operation panel.

 

In Tiptronic mode this push-button can be used to switch 
between job selection and job-set selection.

Current / voltage display

The actual welding voltage and welding current values are in-

dicated during the welding. After the welding procedure, the 

“Hold” LED lights up and the last welding voltage and welding 

current values are indicated. When the operator changes cer-

tain welding adjustments (e. g. level, program, job), the “Hold” 

LED goes out and the reference values for current and volt-

age are indicated.
