• 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).
• The mode E-TIG (Fig 2 - 9)
This mode ensures that the power is stable throughout the weld by measuring the variations in arc length in real time. This is important to ensure a
consistent penetration and weld bead. In case the assembly requires the welding power to be controlled, the E.TIG mode can be used as it is designed
to ensure that the welding power remains the same regardless of the position of the torch.
