TITANIUM 400 AC/DC

Example :
The I welding current is set to a 100A and % (I_cold) = 50%, thus a Cold current of = 50% x 100A = 50A.
F(Hz) is set to 10Hz, the signal period will be 1/10Hz = 100ms -> every 100ms, one pulse at 100A then another at 50A will follow one another.

Description & advice
Pre-gas
0 - 60 sec.
Time to purge the torch and to protect the area with gas before ignition
Starting current
10 - 200 %
This starting bearing current is a phase before the current rise ramp.
Starting time
0 - 10 sec.
Rising current
0 - 60 sec.
Current rise ramp.
Welding current
3 - 400 A
Welding current.
Wave shape
Waveform of the pulsed part.
Cold current/Back-
ground current)
20 - 80%
Second welding current known as "cold" welding current
Cold weather
20 - 80%
Time balance of the warm current (I) of the pulsation
Pulse frequency
0.1 - 2500 Hz
Pulse frequency
Downslope
0 - 60 sec.
Downslope current.
End current
10 - 200 %
This stopping stop current is a phase after the current descent ramp.
End duration
0 - 10 sec.
Post-gas
0 - 60 sec.
Duration for which gas is released after the arc has stopped. It protects the weld pool
and the electrode against oxidisation when the metal is cooling down.
ADJUSTMENT TIPS : The choice of frequency
• If welding with manual metal input, then F(Hz) synchronized to the input gesture,
• If thin without supply (< 0.8 mm), F(Hz) > 10Hz
• Welding in position, then F(Hz) < 100Hz
TIG DC – Fast Pulse
This very high frequency pulsed current welding mode combines high current pulses (I, welding pulse) with low current pulses (I_Cold, part cooling
pulse). Fast Pulse mode allows to keep the arc constriction properties of Pulse mode at high frequencies but still on less unpleasant or even inau
-
dible sound frequencies for the welder.
