1 PREFLOW
In the TIG welding modes, this function controls the
shielding gas Preflow time. In Stick welding mode,
this is not used.
2 START
CURRENT
This function controls the initial current when a TIG
welding is started. For an explanation of the Start
operation, refer to the trigger sequences explained
below.
3 UPSLOPE
In the TIG welding modes, this function controls the
linear increase of the current from Start to Set
Current. Refer to the trigger sequence section
below to understand how Upslope is activated. In
Stick welding mode, this is not used.
4 SET
CURRENT
This function is used to set the Output Current used
during welding.
4a DUTY CYCLE (PULSING ON-TIME)
When the pulse feature is ON, this function controls
the pulsing on-time. During the on-time the output
current is equal to the Set Current.
4b FREQUENCY
When the pulse feature is ON, this function controls
the pulsing frequency, that is the square wave
represented in the diagram above (Hz).
4d BACKGROUND
When the pulse feature is ON, this function controls
the pulsing Background current. This is the current
during the low portion of the pulse waveform.
5 DOWNSLOPE
In the TIG welding modes, this function controls the
linear decrease of the current from Set to Crater
Current. Refer to the trigger sequence section
below to understand how Downslope is activated.
In Stick welding mode, this is not used.
6 CRATER
This function controls the final current value after
the Downslope. For an explanation of the Crater
operation, refer to the trigger sequences explained
below.
7 POSTFLOW
In the TIG welding modes, this function controls the
shielding gas Postflow time. In Stick welding mode,
this is not used.
During welding the Sel pushbutton is enabled for the
following functions:
Output
current
Only if Pulse Function is active: is possible operates
on the values of Duty (%), Frequency (Hz) and
Background current (A).
The new parameter value is automatically saved.
