Tig Welding - GISS TIG 200 A HF AC/DC Notice Originale

TIG WELDING

Select Starting Function
TIG LIFT : Contact start (for environments sensitive to HF disturbances)
HF TIG : High Frequency start without contact
Trigger behaviour
The TIG 200 A HF 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
4T mode
Nb: For dual controls torches and dual potentiometer
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).
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 command + 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.

TIG 200 A HF AC/DC
Select LIFT or HF function.
1- Touch the work-piece with the electrode
2- Press the trigger on the torch
3- Lift the electrode.
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
"up / warm current" and potentiometer active, command «low /
cold current» inactive
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.
1- Press trigger : pre-gas, followed by starting. In order to make the elec-

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.
