To zero set the wire consumption (MIG/MAG)
The machine starts all over again with the calculation of
wire consumption if the two buttons are pressed at the
same time.
Locking of the machine (option)
A lock to the machine can be delivered as
special equipment with the purpose of locking
the adjusted parameters or preventing welding with the
machine. With this lock mounted is is possible to select
between the following functions:
1: Off
The lock is disconnected and the box functions as
normal.
2: Limited lock
Adjustment of the secondary functions, parameter curve
and the synergy function is locked.
3: Full lock
All functions on the control panel is locked together with
adjustement from handle and remote control unit.
Adjustment can only be carried out from the Robot inter-
face.

AUTOMATIC FUNCTIONS

Anti-stick (MMA electrode)
When MMA electrode welding the electrode can stick to
the workpiece. Anti-freeze is always active and if the
machine registers that the electrode is stuck to the work
piece the current will be subsequently lowered. The weld
pool will harden and the electrode can be pulled away,
allowing welding to start normally again.
Interruption by lack of arc initiation (MIG/MAG)
The welding voltage, gas flow, and any wire feed will be
switched off if ignition does not become a welding arc
within 10 seconds.
Re-ignition (MIG/MAG)
If the welding arc is broken by the accidental removal of
the torch from the workpiece then the machine will try to
re-ignite the arc again for up to 10 seconds.
ESTABLISHING NEW SYNERGIC CONDITIONS
New synergic conditions are established by adjusting the
welding parameters at four different currents across the
current range to be used on the welding job. When
welding at these four points the machine is operated in
the same way as manual MIG/MAG welding with or with-
out pulse. After that, when used in the synergic mode the
machine will automatically calculate the correct welding
parameters across the welding parameters across the full
current range to be used.
The following parameters have synergic control in
MIG/MAG welding:
- Wire feed speed
- Voltage
- Electronic choke
- Burn back
The following parameters have synergic control in
MIG/MAG pulse welding:
- Wire feed speed
- Pulse current
- Electronic choke
- Pulse time
- Pulse frequency
Base voltage
-
- Burn back
Starting point for a new synergic program
A new synergic program always starts with an existing
program in the synergic library. The program closest to
the welding task in terms of material, wire and gas is
selected, and welding then takes place with four different
currents across the current range to be used.
Installing the new synergic
program
This is done by pressing at the same
time the RECALL key pad and the
synergic section. The first point on the synergic curve
symbol is then illuminated.
If during the installation of the new program it is
necessary to start again at point 1, then the RECALL key
pad and the key pad in the synergic section are
pressed again.
The first weld is made at the lowest wire feed speed
(current) to be used in the program. Voltage, electronic
choke, burn back, and possible pulse parameters are
then adjusted until the required welding conditions are
established.
Welding can be started and stopped as many times as
necessary and the machine always registers the average
welding current. The first point is at the lowest limit of the
welding current range, with points two and three being
the average currents at two intermediate positions on the
range, and point four being at the highest current setting
to be used.
Optimum welding conditions must be used at each point
and care taken to ensure that the recorded average
current does not differ from the correct value.
The synergic sequence
When the optimum conditions for each point
are obtained the
section is pressed to allow movement to the next point on
the synergic curve. At each new point a higher wire feed
speed is set in order to obtain a higher current.
When optimum conditions at all four points have been
established the installation of the new program is
completed with one last push of the
synergic section. Welding can then continue with the new
synergy.
Too low a current at the synergic point
If an attempt is made to weld at one point with a current
below that used at a lower point, the attempt will be
rejected and error code
disappear after a few seconds and installation of the new
point can start again.
