Operating manual
• TACK WELDING
This welding mode also allows for the pre-assembly of parts before welding, but in two stages this time: the first stage uses a pulsed DC current
which concentrates the arc for better penetration. This is then followed by the second stage where a standard DC current is used to widen the arc and
therefore the weld pool to secure the weld point.
The variable times of the two welding stages allow for better reproduction and non-oxidised weld points.
• E-TIG WELDING
This mode allows for constant power welding by measuring arc length variations in real time to ensure consistent bead width and penetration. In
cases where the assembly requires careful control of the welding energy, the E-TIG mode guarantees that the welder 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 Pre-Gas and
stops at 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 torches, double buttons and double button + potentiometer
T4 => «up/weld current» button turns on the potentiometer, the «down»
button turns it off.
