2.6.1 Welding power adjustment
Adjusting the welding power according to sheet thickness affects
simultaneously both wire feed speed and amount of current lead to the wire.
This is a good starting point for welding in different operating situations.
However, connection type and root opening may influence the amount of
welding power needed.
Select the correct parameter with the welding power control according
to the welded fillet weld's sheet thickness. If the fillet weld's sheets are of
different thickness, use their average as a default parameter.
Sheet thickness scale has been given in millimetres and it is based on 0.8 mm
wire diameter. When using a 0.6 mm wire, set the welding power control
slightly higher than the used sheet thickness and correspondingly slightly
lower with 0.9 – 1.0 mm wires.
NOTE!
When welding for the first time, we recommend that you set the arc length
trimmer to the middle position.
2.6.2 Arc length trimmer
The arc length trimmer adjusts the length of the arc shorter or longer and
affects the welding temperature. A shorter arc is colder and a longer one
hotter. The arc length trimmer also affects the arc's welding properties and
spatters with different combinations of filler wire diameters and shielding
gases.
If the weld is too convex, the arc is too short or cold. Then adjust the arc
longer or hotter by turning the control clockwise.
If, on the other hand, you want to weld with a colder arc to prevent for
example the parent material from burning through, adjust the arc shorter by
turning the control counter clockwise. You can also adjust the welding power,
if need be.
Once the arc has been trimmed, it usually does not need to be changed
when the welded sheet thickness changes.
