Translation of the original instructions
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 200 AC/DC, TIG 200 L AC/DC 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 potentio-
meter 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 pre-
viously set cold current (20% at 70% of hot welding current).
1- Press trigger : pre-gas, followed by starting. In order to make the elec-
trode 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
Nb: For dual controls torches and dual potentiometer
command “up / warm current” and command»
low / cold current « + active potentiometer
For this mode it may be convenient to use the dual torch option or
dual c potentiometer. The «up» command keeps the same function as the simple torch command or slip.
The «down» command can, when pressed, switch to the cold current. The potentiometer of the torch, where available,
allows control of the welding current (warm and cold) from 50% to 100% of the value displayed.
