SETTINGS - AC TIG
• Standard
This welding mode is dedicated to welding aluminium and its alloys (Al, AlSi, AlMg and AlMn). The alternating current allows the aluminium to be
stripped clean, which is essential for welding properly.
Balance (%T_AC):
During the positive wave, any oxidation is removed. During the negative wave, the electrode cools down and the parts are welded together, this
is called penetration.
By changing the ratio between the two alternations via the balance setting, either cleaning is favoured or penetration (the default setting is
30%).
20%: Max. penetration
• Pulsed
This pulsed current welding mode combines strong current pulses (I, welding pulse) with weak current pulses (I_Cold, cooling pulse). This pulsed
mode allows parts to be assembled whilst limiting both the temperature rise and amount of distortion. Also ideal for in-position welding.
Example:
The welding current (I) is set to 100 A and % (I_Cold) is set to 50%, i.e. cold current = 50% x 100 A = 50 A.
F (Hz) is set to 10 Hz, the frequency of the pulse will be 1/10 Hz = 100 ms; this means that every 100 ms, there will be a pulse at 100 A, then
another at 50 A will follow.
• SPOT WELDING
This spot welding mode allows parts to be pre-assembled before welding. Spot welding can be controlled manually using the trigger or by a predefined
time delay. This spot welding time makes it easier to reproduce and produce non-oxidised spot welds.
• Multi-Spot
This is a spot welding mode similar to SPOT TIG but with defined spot welding and stopping times as long as the trigger is held down.
• AC Mixed
This AC welding method is used to weld aluminium and its thick alloys. It mixes DC sequences during AC welding processes which increases the
energy delivered to the workpiece. The ultimate goal is to accelerate the work flow rate and, therefore, subsequent productivity when assembling
aluminium. This mode cleans the workpiece less, so it is important to work on clean sheet metal.

E-TIG
This mode allows welding with a constant power supply by measuring the arc length variations in real time to ensure a weld bead with consistent
width and penetration. In cases where the assembly process requires the welding energy to be controlled, E-TIG mode guarantees that the welder
will respect the welding power regardless of the torch's position in relation to the workpiece.

Mode de soudage synchrone sans interférence lorsque 2 sources de courant AC
sont utilisées simultanément sur la même pièce à souder. Le soudage avec cette
fonction sera synchronisé sur la fréquence du réseau électrique. Les fréquences en
AC seront réduites à la plage 25Hz, 50Hz, 100Hz, 150Hz et 300Hz.
Mains phase adjustment in 60° steps. This setting avoids the need to swap power
