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).

• Spotting - TACK (TIG DC)
This mode can also pre-assemble workpieces, but in two phases : first phase is DC pulse which concentrates the arc for enhanced penetration, fol
-
lowed by a DC standard phase which enlarges the arc and the weld pool for a good spot.
The adjustable duration of each phase enables control of the weld time for better spot welding results and a non-oxidised spot (accessible via the
advanced menu).
