- The indicator by the symbol is illuminated when
the right hand display window shows the trim
value in volts.
The actual welding voltage is always shown in the right
hand window during welding and the final welding voltage
is displayed for two seconds after welding has finished.
When not welding the right hand display window shows:
- MMA electrode:
Open circuit voltage (cannot be altered).
- Manual MIG/MAG without pulse:
Voltage adjustment. Voltage can be adjusted between
0 and 50 volts.
- Manual MIG/MAG with pulse:
Adjustment of base voltage. Voltage can be adjusted
between 0 and 50 volts.
- Synergic MIG/MAG:
Trim value adjustment. Trim value can be adjusted
between - 9.9 and + 9.9 volts.
Trim (MIG/MAG)
When synergic welding the voltage is controlled
by the synergic current. The trim value is a parameter
which determines by how many volts the voltage has to
be adjusted - either up or down - in relation to the value in
the synergy.
Voltage
The trim value can adjust the arc length and so cater for
different welding procedures and plate thicknesses. It can
also be used to compensate for using a gas mixture other
than the one stated in the synergic library.
V-key pad
The right display can be used to show a line of
parameters besides voltage / trim. A push on the
pad brings the right display back to showing of voltage /
trim.
Displaying measured values
The measured values of current and voltage of the
last welding activity can be displayed by pushing the
RECALL key pad.
Choice of machine settings
There is a choice between 10 complete
machine settings, representing all parameters. The
machine settings are numbered 0 to 9 and the number
selected is shown in the display between the key pads. A
push on the key pad produces the next machine
setting. When on machine setting number 9 a push on
the key pad produces setting number 0. In the similar
way a push on the key pad shifts to machine settings
with lower number. All machine settings will be retained
by the machine even if there has been a change of
settings.

Synergic library (MIG/MAG)
The machine has a library of synergic programs. On the
inner side of the cover in the one side of the wire feed
unit there is a list of the contents of the synergic library.
(fig. 2, page 95). The following procedure describes how
to access a synergic program from the library.
Selection of machine settings:
Before a program can be accessed the
machine settings containing that synergic program must
first be selected.
Opening the synergic library:
Pushing on the RECALL and
the same time opens the synergic library. The letter "P"
appears in the left hand display while the right hand
display shows the synergy number (from the synergic
library) that is to be selected later in this procedure.
Selecting synergy:
The key pads are used to display the required
synergic number in the right hand display.
Accepting the synergy:
When the required synergy is found it is trans-
ferred to the machine setting by pressing the
after which the machine will return to normal operation.
is shown in the left display if the selected position
does not contain a welding programm.
Rejecting choice of synergy
The choice of synergy can be rejected by pressing
the RECALL key pad and the synergy will not be
changed. This procedure can also be used if it is only
necessary to see which synergy has been selected in the
actual program.
Sequences
(Electrode and MIG/MAG)
Use of the sequence facility enables the welder to switch
between two or more current levels. Changes can be
made both before and during welding. A sequence allows
adjustments of those parameters which have an effect on
the actual welding process.
These parameters are:
In manual MIG/MAG welding
- Wire feed speed
- Voltage
- Any pulse parameters (pulse time, pulse frequency,
pulse current and base voltage)
- Burn back time
In synergic MIG/MAG welding
- Synergic current
- Burn back time
In MMA electrode welding
- Welding current (/pulse current)
- Any pulse parameters (pulse time, pulse frequency and
base current)
Switching between sequences:
Any particular sequence can be selected with the
sequence key. When a sequence is selected an indicator
beside the sequence number to the right of the
pad is illuminated. When there is no light in any of the
sequence numbers then the sequence is not in use.
