3.3.18.7 Hot start ( H )
In order to improve the ignition when stick-electrode welding, the ignition current
is given a short boost when starting. This hot start current is higher than the
welding current that has been set (I1). The setting value for the hot start is a
direct relationship to the welding current. The setting can be adjusted between
0% and 70%; this means that with a setting of 30% (H30) and the welding current
of 100A the hot start current is 130A.
3.3.18.8 Arc Force ( I )
In order to ensure a stable arc during stick-electrode welding it is very important
for the smooth droplet transfer that in addition to the welding current (I1) that a
very short current pulse is also given by the welding unit this is called the Arc
force. The size of the pulse is defined by the Arc force setting which can be
infinitely variable from 0% to 70% of the welding current (I1) which is set, this
means that with a setting of 50% (I50) and the welding current at 100A the arc
force current will be 150A.
3.3.18.9 Program save and load ( S ) ( L )
There can be up to 99 different programmes with machine settings stored under
a freely selectable programme number and recalled for use. All for the machine
parameters settings that can be set are stored and then reloaded for
implementation.
Thereby the entire machine settings can be simply reloaded for those repeat jobs
within seconds saving a great deal of time and ensuring consistent quality
Additionally the basic parameter setting of the machine such as the start current,
crater fill current, ignition energy, etc. can be individually set for each person who
uses the machine. Recalling these is done at the touch of a button.
Loading a programme:
Selecting the load setting in the special mode does the loading of a
programme. The first digit of the digital display shows the letter „L“ which
stands for
L
oad
By depressing the turn and set knob the function load is activa
ted and the „L“
begins to blink.
The turn and set knob is then turned and the required programme number can
be selected.
The turn and set knob is depressed once again for
more than 2 seconds
and
the selected programme number will be loaded into the machine. The loading
of the programme can be recognised as the display will go blank for a short
time, additionally the LED’s will change their position according to those
determined by the programme settings.
Saving a Programme:
Selecting the load setting in the special mode does the loading of a
programme. The first digit of the digital display shows the letter „S“ which
stands for
S
ave.
Depressing the turn and set knob activates the load function, and the „S“
begins to blink.
The turn and set knob is then turned and the required programme number can
be selected.
The turn and set knob is depressed once again for
more than 2 seconds
then all of the parameters which are set at that time will be saved. The saving
of the programme can be recognised, as the display will go blank for a short
time. The knob must be pressed for more than 2 seconds in order to prevent
the accidental saving or overwriting of an existing programme, (similar to a car
radio).
