Calibration
The first time you use QSet mode, and when you change welding wire, material or
shielding gas, you need to allow QSet to calibrate. This is done by making a test
weld (min. 6 seconds). Simply start welding and let QSet find the correct parameter
settings.
Material selection
Since different materials have different heat dispersion, it is necessary to select the
right material group (H) so that a correct plate thickness value can be calculated.
Settings for cored wire is done only in manual mode.
Plate thickness setting
Set the plate thickness of the object you want to weld using the plate thickness
setting knob (I). This knob sets the wire feed speed (C). A suitable voltage setting is
automatically calculated by QSet. The recommended plate thickness for the set wire
feed speed is displayed simultaneously (D). The plate thickness recommendation is
calculated for a fillet weld using the following wire dimensions: Fe/Ss and CuSi -
.030", Al -
.40". If you use a smaller diameter wire you should set a slightly higher
value for plate thickness than what you are going to weld. If you use a larger
diameter wire set a slightly lower value.
Heat input adjustment
The heat input can be adjusted with the QSet knob (F) in steps from -9 to +9 to make
the weld hotter or colder. A higher value gives a hotter, more concave, weld (longer
arc length) for more penetration. A lower value gives a colder, more convex, weld
(shorter arc length) to prevent burning through the workpiece. Typically the QSet
value should be set to 0 which gives you an average heat input that is suitable in
most cases. The heat input setting is symbolised with a thermometer indicating
hotter or colder settings.

Unit of measurement
The setting of the unit of measurement is a hidden fuction. The default value for the
power source is mm. This can be changed to inch by pressing the pushbuttons G
and H and holding them pressed in 5 sec. With the help of the knob (I) the required
unit of measurement is selected.
