TITANIUM 400 AC/DC
The Balance (%T_AC):
during the positive wave, the oxidation is broken. During the negative wave, the electrode cools and the parts are welded, there is penetration. By
modifying the ratio between 2 alternatives through the balance adjustment, you choose either cleaning or penetration (the default value is 30%).
20%: Max. penetration
The frequency (AC Hz):
the frequency allows you to adjust the concentration of the arc. The higher the frequency, the more concentrated the arc. The lower the frequency
the wider the arc will be.
High Low
TIG AC - Pulse
This pulsed current welding mode is a combination of high current pulses (I, welding pulse) and low current pulses (I_Cold, part cooling pulse). This
pulse mode allows to assemble pieces while while keeping the machine cooler.
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 2Hz, the signal period will be 1/2Hz = 500ms -> every 250ms, one pulse at 100A then another at 50A will follow one another.

TIG AC - MIX
This method of alternating current welding is used to weld aluminium and its thick alloys. It mixes DC periods whist welding in order to increase the
energy flow to the workpiece. The final goal is to accelerate the work advance and therefore productivity on aluminium assemblies. This mode pro-
duces less pickling so it is necessary to work on clean sheets.

THE TIG DC or AC TIG POINTAGE
SPOT (TIG DC or AC)
This welding mode allows the pre-assembly of the parts before welding. Scoring can be manual by trigger or delayed with a predefined scoring delay.
This pointing time allows a better reproducibility and the realization of non-oxidized point (accessible in the advanced menu).
