1. Return to standard control panel
2. Selecting program
3. Recall of factory settings
Reset the chosen program to factory settings.
4. Gas test
a. Setting manual gas/IGC (not all versions)
b. Gas test
c. Calibration of IGC (not all versions)
5. Arc adjust
Makes the arc warmer/colder by up- and
downgrading the droplet transfer during
welding. Micro spatter can be reduced in DC.
The arc pressure and arc speed can be
increased by deeper penetration in pulse
welding.
6. Machine settings
a. Cable compensation
For calibration of the resistance in the
welding hose.

b. Torch
Selecting torch
and 2-times/4-times trigger mode.
2-times: Welding starts when the
torch trigger is pressed down. To end
welding, release the torch trigger, after
which burn back starts. It is possible to
trigger the machine again during post flow.
4-times: Welding starts when the
torch trigger is held down. The trigger can
then be released and welding continues.
To end welding, press down the torch
trigger again, after which burn back starts.

Parameter
1 Pre-flow Pre gas ensures gas coverage before welding.
Pre gas time is the time from activating the torch
trigger until the wire feed starts.
2 Soft start Soft start improves the ignition characteristics. Here
speed with which the wire shall start is set.
3 Hot-start Hot-start is a function that helps to create the right
value temperature in the weld pool at the beginning of a
weld.
4 Hot-start Hot-start time determines the time in which welding in
time hot-start takes place
5 Slope-down The time of the current slope-down is set. By
activating the trigger, the slope down begins in order
to make a crater filling.
6 Final current The current is reduced from set current to final
time current.
7 Final current Welding stops at a percentage of the welding current.
8 Post gas Post gas is the time from which the arc extinguishes to
the gas flow being disconnected, so the gas coverage
is ensured.
9 Arc power The arc power function is used for stabilising the arc
in MMA-welding. This takes place by increasing the
welding current during short-circuits. The extra current
is disposed off, when there is no longer a short-circuit.
* Changes in values according to the factory settings are indicated by changing parameter icons to
green colour.
** Pre gas and post gas can be reduced for faster tack welding (may result in lack of gas shielding)
