Post-flow [s]:
Post-flow is the period of time for which gas
flows after the arc is extinguished and is variable 0-
20 sec.
Pulse welding
In this section it is possible to choose
between no pulse, slow pulse and fast
pulse.
No pulse
Welding with no pulse has been selected.
The pulse parameters cannot be activated.
Slow pulse: (TIG DC and TIG AC)
It is possible to adjust:
- Pulse time (s)
- Pause time( s)
- Base amp [A%]
Fast pulse: (TIG DC only)
It is possible to adjust
- Base amp [A%]
- Pulse frequency [Hz]
The pulse time and the pause time will be equal.
Slow pulse parameters:
The following parameters can be
selected in this section:
Pulse time:
Adjustable from 0.1 to 10s in steps of 0.1sec
Pause time:
Adjustable from 0.1 to 10s in steps of 0.1sec
Base amp:
Adjustable from 10 to 90% of the pulse amp.
TIG AC-balance
In AC welding this section allows to
adjust the cleaning/penetration balance.
Penetration can be adjusted from 15% to
85%.
Electrode pre-heating (TIG AC)
Pre-heating of the electrode will improve the ignition.
It is possible to select 15 levels of pre-heating. It is
suggested to use the following selection:
•
5-8 for 1.6mm electrodes
•
8-12 for 2.4mm electrodes
•
12-15 for 3.2mm electrodes
To adjust the pre-heating push this key for
more than 5 seconds. The light will flash
quickly and the display will show the level of pre-
heating.
To exit this function wait 5 seconds or push this key
again.
TIG spot welding
It is possible to store a spot welding program to allow
a quick switch from welding to spot welding. In this
mode the following features will be available:
•
Arc ignition HF 2-times
•
No slope-up/slope-down
•
Pre-flow 0.2 sec
•
No pulse
The spot welding program is selected by pushing
this keypad for 3 sec:
The LED indicated the TIG torch will lit: it is now
possible to adjust the spot welding current.
To return to welding program push this key again.
