Sequences can be changed by pushing the
before or during welding. When using the MIG/MAG
welding process the torch trigger can be used to shift
between sequences. If not actually welding, it is possible
to switch between sequences with a quick push on the
trigger. The procedure for switching sequences when
welding depends on which key function is selected. If 2-
times welding ( ) is selected then the trigger has first
to be released and then pushed quickly (within 0.3
seconds). If 4-times welding (
is selected then the trigger has first to be pushed and
then released quickly.
Torch trigger control (adjustment of the welding current
from the torch) and the sequence function must not be
selected at the same time as an adjustment on the trigger
influences all sequences and not just the sequence used
for welding.
Selection of the number of sequences:
Up to four sequences can be installed. The
number of sequences can be decided by
installing number 0 in the left hand display window after
the last required sequence, e.g. two sequences are re-
quired, so 0 is installed in sequence number 3. The
machine automatically switches from the last sequence
back to sequence number 1.
Welding voltage indicator
The welding voltage indicator is illuminated as a
precaution when there is voltage on the electrode or the
torch.
SELECTION OF FUNCTION
Selection of key function
(MIG/MAG)
This key pad is used for the selection of trigger function.
The selected function is shown on the indicators to the
right of the key pad.
2-times:
Welding is started by pushing the trigger and stops
when the trigger is released.
4-times:
Welding is started by pushing and immediately re-
leasing the trigger and stops when this action is repeated.
Spot welding:
Welding is started with a push and immediate re-
lease of the trigger and continues for a pre-set time. The
time is set on the parameter: spot welding time.
Choice of manual or synergic function
(MIG/MAG)
The key pad in the synergic section is used to
switch between synergic and manual MIG/MAG
welding. The indicator by the key pad is alight
when the synergic function has been chosen.
key pad
) or spot welding ( ),
Manual welding:
When selecting manual MIG/MAG welding:
- Wire feed speed and voltage are at their minimum
values of 1.0 metre/minute and 0 volts respectively.
- Sequence is switched off.
- Pulse welding is switched off.
- Torch cooling method is watercooling.
Synergic MIG/MAG welding:
When selecting synergic MIG/MAG welding:
- The synergic current is at the minimum value in the
selected program.
- Trim is at 0 volts.
- Sequence is switched off.
- Torch cooling method is watercooling.
Adjustment methods for current /
voltage / wire feed speed
Use of this key pad selects the method
by which current, voltage and wire feed speed can be
adjusted.
Local control:
In this method the key pads on the machine are
used for all adjustments.
Remote control:
Adjustments are made from a remote control
connected to the machine. The following machines
and parameters can be adjusted by use of a remote
control.
- MMA electrode : current
- Synergic MIG/MAG : synergic current and trim
- Manual MIG/MAG : Wire feed speed and voltage
Torch trigger control (MIG/MAG)
Fine adjustment is made on the control wheel on
the welding torch if there is one. Fine adjustment can be
made within +/- 50% of the central value which is set at
the expected welding current. However, the maximum
and minimum values of the machine cannot be
exceeded. The following machines and parameters can
be adjusted by torch trigger control:
- Synergic MIG/MAG
- Manual MIG/MAG
For example:
If the key pads have been used to set a current of 180
amps, torch control allows an adjustment of +/-90 amps,
that is a current range of 90 amps to 270 amps.
Cooling of welding torch (MIG/MAG)
The machine has a cooling module which is
switched on and off by pushing this key pad.
Gascooled torch:
When this indicator is not alight the cooling module is
switched off and the torch is cooled only by the shielding
gas.
Watercooled torch:
The torch cooling unit has been connected and the
indicator is alight.
