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.
