User manual
Example:
The welding current (I) is set to 100 A and % (I_cold) = 50%, i.e. cold current = 50% x 100 A = 50.
F(Hz) is set to 10 Hz, the signal period will be 1/10 Hz = 100 ms -> a 100 A pulse every 100 ms then followed by another at 50 A.
• SPOT
This welding mode allows the pre-assembly of parts before welding. Spot welding can be done manually using the trigger or timed with a predefined
spot welding period. Spot welding allows for better reproducibility and non-oxidised weld points.
• TACK
This welding mode also allows for the pre-assembly of parts before welding, but in two stages this time: the first phase is pulsed DC to concentrate the
arc for better penetration, followed by a second phase in standard DC to widen the arc, and therefore the weld pool, to ensure the spot.
The adjustable times of the two phases allow for better repeatability and non-oxidised points.
• E-TIG
This mode ensures consistent welding power by measuring variations in arc length in real time to ensure uniform bead width and penetration. In cases
where the assembly requires careful control of the welding power, E-TIG mode guarantees that the machine will respect the welding power regardless
of the torch's position in relation to the workpiece.

T1 - The main button is pressed, the welding cycle starts (Pre-Gas,
I_Start, upslope and welding).
T2 - The main button is released, the welding cycle is stopped
(downslope, I_Stop, Post-Gas).
For two-button torches in T2 only, the secondary button is treated as
the main button.
T1 - The main button is pressed, the cycle starts from the PreGas
and stops in the I_Start phase.
T2 - The main button is released, the cycle continues to upslope
and welding.
T3 - The main button is pressed, the cycle goes to downslope and
stops in the I_Stop phase.
T4 - The main button is released, the cycle ends with the Post-Gas.
NB: for double button, and double button + potentiometer torches
=> the «up/weld current» button and potentiometer are active, the
T4
«down» button is inactive.
