6.2 PLF – Plasma gas Flow.
Plasma gas flow rate during welding (second level current). Shown by D2 (with L2 on) and adjustable with M1 when
L5 is on.
Range = 0.2 ÷ 10.0 l/min.
Default = 1.0 l/min.
From the TIG touch panel: MENU -> Plasma Welding Parameters -> Gas Flow Rate
SHF – Shield gas Flow.
Shield gas flow rate during welding (second level current).
Shown by display D3 (with L2 on) and adjustable with M1 when L6 is on.
Range = 5.0 ÷ 30.0 l/min.
Default = 1.0 l/min.
From the TIG touch panel: MENU -> Plasma Welding Parameters -> Shield Gas Flow Rate�

SECOND FUNCTIONS

To access the "Second Functions" menu from PW30 press knob M1 for longer than 2 seconds; display D1 shows the
function code (LED L4 on) and displays D2 and/or D3 show the values allocated to the function.
Select functions by turning M1�
To change the value of the function indicated by D1, press M1 for under 2 seconds to select the value to be changed (L4
off, L5 or L6 on) and turn M1 to change the value shown by D2 or D3�
To save the changes made and exit the "Second Functions" menu press M1 for longer than 2 seconds.

For greater clarity, some of the functions described below are shown in the diagram in section 9
Access this menu on the TIG power source by selecting: MENU -> Plasma Welding Parameters
7.1 PPt – Plasma Preflow time.
Plasma gas preflow time, i.e. the time between the pilot arc start command and the HF trigger to start the pilot arc.
Range = 0.0 ÷ 10.0 s.
Default = 2.0 s.
From the TIG touch panel: MENU -> Plasma Welding Parameters -> Pregas Duration
7.2 PPF – Pre and Post Pilot Flow.
Plasma gas flow rate during PPt�
Combining PPF and PPt improves the pilot arc start.
Range = 0.2 ÷ 10.0 l/min.
Default = 1.0 l/min.
From the TIG touch panel: MENU -> Plasma Welding Parameters -> Pregas Flow Rate
7.3 PAF – Pilot Arc Flow.
Flow rate of plasma gas, when welding current is not yet present.
Range = 0.2 ÷ 10.0 l/min.
Default = 1.0 l/min.
From the TIG touch panel: MENU -> Plasma Welding Parameters -> Pilot Arc Gas Flow Rate�
