welding process starts. The current will go to the set value with a slope up value
of 1/4 t with respect to the time set for the slope down..
By pressing the torch button briefly (less than 0.5 seconds ), you can pass directly
from the set current value A to the final current value FC and vice versa.
End of welding:
1) Hold down the torch button for more than 0.5 seconds: the current gradually
falls with the time set by means of the SL button (ref.8 page 9); the arc remains at
the final current value set with the FC button.
2) Release the torch button: the arc goes out and then there will be the POST-
GAS time set by means of the PG button (ref.15 page 9).
Procedure for TIG WELDING WITH REPAIR (DOUBLE PARAMETER) with LIFT
start (without HF)
Starting welding :
1) Check that the HF ON led (ref.7A page 9) is off. If it is not, press the HF ON but-
ton (ref.7 page 9) ; the HF ON led goes off (ref.7A page 9).
2) Bring the tip of the electrode (tungsten) into contact with the piece to be welded.
3) Press the torch button: gas will come out immediately.
4) Release the torch button: lift the torch from the side so as to move slightly away
from the piece to be welded and start the welding process; the current will go to
the set value with a slope up value of 1/4 t with respect to the time set for the slope
down.
By pressing the torch button briefly (less than 0.5 seconds ), you can pass directly
from the set current value A to the final current value FC and vice versa.
End of welding:
1) Follow the same procedure described for TIG WELDING WITH RESET
(DOUBLE PARAMETER) with HF start.
FunCTion OF STORING AND LOADING WELDING PARAMETERS (job mode)
Function active for all welding modes
This function allows you to store and load all the settings made on the generator at
any time. It is possible to save 99 welding parameters (settings) .
STORING WELDING SETTINGS
1) Hold down simultaneously for 1 second the buttons PG (ref.15 page 9) and F
(job mode) (ref.17 page 9); you will hear a double sound of the buzzer and the let-
