Special Functions

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.

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 new DSI function has been developed to reduce the energy during the arc ignition phase in order to minimize as much as possible the number of spatters related to the wire explosion.

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.

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.

The new Pulsed HC (High Control) has the characteristic of having a very fast arc control in order to optimize the detachment of the drop with a very reduced energy.

The application was created to stabilize penetration during welding, regardless of changes in the stick-out length.

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

Digital control and excellent welding with cellulosic electrodes is an optimized combination also for piping and Oil & Gas industry applications.

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.

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.

The special function Power Focus has been designed to cut total welding costs, reducing the total number of joints to be welded.

The Power MIX process has the purpose of reducing the average heat input in order to be able to perform welds in an ascending vertical position, corner seams or external corner seams in all positions with an excellent aesthetic result of the joint and free from defects.

The special Power Root function is a short arc transfer, controlled with a cold drop which ensures a very high quality during the root passes.

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.

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 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 pulse TIG with frequency until 2500Hz allows to weld very thin materials with easy arc control and very low heat input on workpiece.

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