GYS TITAN 400 DC Mode D'emploi page 30

• PULSE TIG
This pulse welding mode create alternative high current pulses (I, welding pulse) and low current pulses (I_cold, pulses to cool the piece). This pulse
mode allows to assemble pieces while while keeping the machine cooler.
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, a 100A pulse then a 50A pulse will succeed each other
Advice :
The choice of frequency:
- If welding with TIG electrodes, then F(Hz) synchronised to the gesture,
- If thin plate without TIG electrodes (< 8/10 mm), F(Hz) >> 10Hz
- If special metal requiring a welding pool sweep for degassing, then F(Hz) >> 100Hz
TIG WELDING PROCESSES
• Spotting- SPOT
This mode is recommended to pre-assemble workpieces before welding.
The adjustable spot weld duration enables control of the weld time for better spot welding results and a non-oxidised spot (accessible via the
advanced menu).
