Torch control functions UP/DOWN
The torch control functions are available if up/down
module on the torch is assembled on torch and "Option
50" is enabled in the Setup Menu. There are two functions
available:
Option 50 "Cur" change set current value:
Three operating modes, corresponding to different states
of the machine, are identified:

Before welding: pressing the UP or DOWN key
causes a change of value of the Set current

While welding: pressing the UP or DOWN key causes
a change of value of the Set current during all phases
of welding process except during the start functions,
where the UP/DOWN function is masked.

Pre/post Flow: pressing the UP or DOWN key causes
a change of value of the Set current.
The change will be realized in two ways depending on
pressed button time:

Step function
Pressing the UP/DOWN button for a minimum time of
200ms and releasing it, causes the set current
raises/falls of 1A.

Ramp function
Pressing the UP/DOWN button for a time greater
than 1 sec., the set current start to increase/decrease
with a (5A/s) ramp. If press for more then 5 ses
increase/decrease with a ramp of (10A/s).
The current ramp will end when the UP/DOWN button
previously pressed is released.
When a remote (pedal or RC-pot) device is present,
depending on welding process selected, the UP/DOWN
behavior is different.
SMAW:
In SMAW welding mode, the remote device set the
amperage setting in the whole range, bypassing the main
control knob in front User interface. In that case the
signals coming from UP/DOWN are ignored.
GTAW:
In GTAW mode of welding, the remote device set the
percentage of the main set delivered by the machine.
Regulating the main amperage, the UP/DOWN with
remote device will work as described above.
Option 50 "Job" Change memory:
By pressing torch buttons user will be allowed to change
over settings stored in memory locations from 1 to 9. The
feature is not available during welding.
