AC Frequency
If the pushbutton S4 is held down for more than 2
seconds the AC frequency (Hz) parameter is selected
and can be adjusted using the Current/Function Control
(F1). Pushing the pushbutton S4 again in a short period
of time, the AC balance (%) parameter is selected and
can be adjusted again using the Current/Function
Control (F1).
After few seconds without any changes, all the
parameters are confirmed and the display D1 shows the
welding current.
The parameter defaults and usable ranges are shown
here.

Set-up Menu
To access the set-up menu start with the machine OFF.
Press and hold the parameter selection button (S4) and
turn the machine ON. In this mode you can now scroll
through the set-up menu numbers using the
current/function control (F1). Select a number in the
menu you want to change, then press the parameter
button (S4). Now you can change the values, using the
current/function control (F1). When the desired values
have been changed press the parameter selection
button (S4) again to save the new value. To exit this
set-up menu, use the current/function control (F1) to
scroll through to 0 and press the parameter button (S4).
The display then reverts back to the main current setting
and normal operation is possible.
The following parameters can be adjusted.

16 AC Start Power (For AC TIG only)
This function sets the initial start energy
limit. Set this number to a higher setting
than the factory default if needed to
improve starting of large diameter tungsten
electrodes.
0.5 to 1.0 = manual start energy setting
1.2 to 5.0 = max. incrementing limit (*)
(*) The machine will try to start the machine
at a start power of 1. If the arc does not
establish it will incrementally increase the
start power and try to restrike up to the set
limit.

S5 - Pulse ON/OFF: The LED beside the symbol will
light up to confirm the selection: Pulse ON or OFF.
The led on the graphic display is indicating the function
and the display will show the parameter. You may select
the function by pushing the parameter button (S4) and
adjust the setting with the current/function control (F1).
