Welding sequence:
You can press the button to
preselect a "standard" or "short"
basic welding sequence. If you
select "short", a shortened gas pre-flow time results in a
shorter time gap for triggering in a series of welding
points.
•
Language
Pressing the button with the
country
codes
enables
the
system language for the welding
device to be changed. The system can be toggled
between English (EN), German (DE), Spanish (ES),
French (FR) and Italian (IT).
•
Welding signal tone:
Pressing the button activates or
deactivates the acoustic signal that
notifies the triggering of the weld.
•
Retention welding:
Pressing this button activates or
deactivates the operating menu for
welding
retentions.
When
activated, the corresponding menu appears as an
additional user level. The user levels can be toggled by
pressing the power regulator.
6. SELECTION OF THE WELDING PARAMETERS AND USER LEVELS
6.1 SELECTION OF THE WELDING PARAMETERS
Pressing for a short time (< 1 second) the rotary controller (25) or touching the POWER or TIME scales on the display
switches between the power (POWER) and pulse duration (TIME) parameters. It jumps back to power (POWER)
automatically after 1 second. Rotating the rotary controller or sliding the power (POWER) or pulse duration (TIME) scales
changes the relevant value.
BASIC INFORMATION ABOUT THE EFFECTS OF WELDING POWER AND WELDING TIME:
POWER:
With the parameter “welding power” the strength of
welding energy is set.
The size and intensity of the welding points are controlled
in this way, i.e. the higher the power the larger the welding
point.
With very thin materials too high a power level can also
quickly result in damage, i.e. it makes sense to experiment
with samples for beginners with the PUK system to find
the optimum power level, starting at a power of 20 % or
with very fine welding, even lower. Power settings
between 35 and 50 % are considered medium welding
powers.
Most dental alloys can be welded with higher power levels,
just as with stainless steel. Power levels above 70 % are
only practical in the most unusual circumstances. There is
a danger of inhomogeneous welds and only experienced
users should move outside this range.
WELDING TIME OR PULSE DURATION:
The welding time setting determines for how many
milliseconds the welding power is applied, i.e. a longer
pulse duration results in a longer and deeper application of
the energy to the workpiece and thus simultaneously a
greater development of heat.
With very thin materials or wires it is recommended to use
a shorter welding time, primarily when welding near to
acrylic or ceramic parts or other heat-sensitive materials.
Welding times of no more than 4 msec are recommended
here.
With some cobalt chromium alloys, with silver alloys or
other highly conductive metals a longer welding time can
be advantageous in order to avoid hot cracks, starting at
10 msec.
