IMPORTANT FOR SUCCESSFUL OPERATION WITH THE PUK:
Welding power and pulse duration must be considered in
close context with each other in all cases! The total energy
applied to the workpiece is comprised of these two
parameter settings together - prior to welding this must be
considered carefully following an in-depth analysis of the
welding task, the materials and the workpiece geometry.
SELECTION OF THE WELDING PARAMETERS ON PUK04:
The welding parameters are set in two stages:
1.
In the upper area of the display, the metal to be welded is selected by means of pressing the
arrow buttons.
2.
Pressing one of the 5 buttons in the centre of the display selects the given welding situation.
This selection causes numerous settings to be made in the background. The important information for the user is then
shown on the display:
A welding time is preselected and the recommended
setting range for the selected welding situation is
marked next to the scale by means of a blue bar.
Settings outside of the recommended blue setting range
are
always
possible,
however,
they
are
not
recommended for the selected welding situation.
The power is also preselected and the recommended
setting range for the power is marked with a blue bar.
Settings outside of the recommended blue setting range
are
always
possible,
however,
they
are
not
recommended for the selected welding situation.
DESCRIPTION OF THE WELDING SITUATION WITH ASSOCIATED SYMBOL ON TOUCHSCREEN:
In the start level, the meaning of the following symbols
is always the same for each of the preconfigured
materials.
The start level shows in addition to the welding power
and pulse duration for each stored material also the
recommended working range in the respective scales of
the touchscreen, highlighted in colour.
Universal setting for material thicknesses
from 0.3mm. This is well suited for most
applications (
≥0.3mm).
Setting for thin sheet metal or wire parts
equal to or less than 0.3mm (
≤0.3mm). This
setting offers very low development of heat,
especially for short welding times.
Welding in sharp angles and tight joint
situations. Here it is IMPORTANT to use
short welding times of 2 to 5 ms.
Melting of welding wire. Use identical alloy
wire with a diameter of 0.3 to 0.4 mm. Ideal
is a diameter of 0.35mm.
Application of welding wire on claws and
stone
settings.
Particularly
low-energy
melting of welding wire in diameter
≤
0.25mm.
PUSHING/TOUCHING THE RESPECTIVE BUTTON FOR AN EXTENDED PERIOD
BRINGS UP AN INFO WINDOW ON THE DISPLAY. SEE 6.3 "HELP FUNCTION"
