The Q START (Quick Start) function facilitates joining of the parts in the initial stage of the welding process.
On activating this function the machine automatically switches to Synergic pulsed mode for a preset time. The
resulting pulses create movement of the molten metal on the two sheet metal edges thereby accelerating formation
of the join.This function is invaluable in the case of seams with slight openings or with irregular preparation. The
duration of the series of pulses can be adjusted, (from 0.1 to 60 second) depending on the thickness and shape
of the sheet to be welded.
The DYNAMIC ARC function makes it possible to keep the product of Voltage x Current constant. The power
source increases the welding current as the arc voltage decreases and reduces the welding current if the arc
The Q-SPOT (Quick Spot) function makes it possible to minimise tacking times for light gauge sheet metal. The
operator conveniently places the tungsten electrode on the fixing point, thereby obtaining perfect control of the
position of the join. Once the electrode has been lifted the machine emits a very high intensity welding current
pulse with a very short preset time (from 0.01 Sec to 10 Sec). The pulse time varies depending on the type of
sheet metal to be joined. In this way the welded point closes instantly with
minimum heat transfer, leaving the metal white, clean and almost cold.
The MULTITACK system makes it possible to reduce heat output while joining two light gauge parts. The series
of arc strikes at short time intervals allows the material to cool during the pause between one strike and the
next and thus minimize its deformation. The facility to adjust the frequency of the series of arc strikes in the
time unit makes it possible to adapt the electric arc to the welding speed and the joint geometry.
This makes it possible to create a highly penetrative and precise fusion bath so that very light gauge sheets can
be welded with an electrode tip comparable to that of an electrode for DC – TIG welding.
