Operation Manual

11/64
Adjustable Arc Force
The Arc Force is adjustable (between 0 and 100%) within the limit of 160A.
1- Press and hold the “Arc Force” button
2- Select the required setting
TIG WELDING
Select Starting Function
Select LIFT or HF function.
TIG LIFT : Contact start (for environments sensitive to HF disturbances)
1- Touch the work-piece with the electrode
2- Press the trigger on the torch
3- Lift the electrode.
HF TIG : High Frequency start without contact
Trigger behaviour
The TIG 207FV/208 automatically detects the type of torch that is connected. (Suitable for various kinds of
TIG torches: trigger, simple command, dual command, dual potentiometer)
2T mode
1- Press and hold trigger : pre-gas, up slope, welding
2- Release trigger : down slope, post-gas
NB: For dual control torches and dual potentiometer  command “up / warm current” and potentiometer
active, command "low / cold current" inactive
4T mode
1- Press trigger : Pre-gas, followed by start. In order to make
positioning the electrode easier, a low current is supplied acting like a
light beam. (=Adjust Ideal Position)
2- Release trigger : Up-slope until the displayed instruction, welding
3- Press trigger : Down-slope to low current (allows good closure of
the crater)
4- Release trigger : stops the current and post-gas.
Nb: For dual controls torches and dual potentiometer  command “up / warm current” and potentiometer
active, command "low / cold current" inactive
4T Log mode
This mode is the same as the 4T mode but when in welding phase, a short tap on the trigger allows a shift
to a previously set cold current (20% at 70% of hot welding current).
1- Press trigger : pre-gas, followed by starting. In order to make the
electrode positionning easier, a low current is supplied, acting like a
light beam. (=Adjust Ideal Position)
2- Release trigger : elevation of the current to the "hot" welding
current (displayed instruction)
short impulse : shift to cold current (%I)
short impulse : back to the "hot" current.
3- Press trigger : down slope to low current (for a good closure of the
crater)
4- Release trigger : stops the current and post-gas.
