Discovery 3200 AC/DC TIG welding machine gas cooled

Pre-set balanced parameters, stored in the Synergic Pulse TIG DC SYN curve, simplify Pulsed welding by adjusting only welding current.

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 voltage increases.

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.

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.

This allows to obtain high welding speed and creating the weld puddle rapidly on a cold workpiece.

Weco pulsed technology up to 20 kHz generates an ultra-high density arc, ensuring full thermal control on material thicknesses from 0.5 to 2 mm, while delivering flawless penetration in root passes on heavy-duty joints.

The Q-SHAPE function enables optimal electrode tip shaping according to the selected electrode diameter before welding begins. This function ensures fast and precise arc starts and stable arc control without deviations, even at low amperage. It is also possible to set three different tip-shaping levels to adapt the process to the operator’s specific needs.

AC Sync allows two power sources to weld simultaneously on the same joint. Thanks to this function, electrical interference between the two arcs is minimized, enabling the welders to operate in perfect synchronization.

The Multi-Pulse function introduces new adjustment possibilities to enhance welding performance through targeted heat input and smoother control of the weld pool. Welding results can be influenced and optimized through different parameter combinations, allowing greater control over the process. This makes it easier to work even on thin sheets, while improving the final appearance of the joint and achieving high-quality aesthetic results.
