Weco Discovery 220T EVO DC TIG Welding Plant

Discovery 220T Evo is a revolutionary state-of-the-art single phase portable TIG DC welding Inverter.

Ordinary steels, stainless steel and copper can be easily welded in TIG DC.
Discovery 220T Evo is specifically designed for extremely precise welding in the construction, petrochemical, food industries and other applications that require very a high welding performance.
The new user interface (Evo) provides fast and effective access to all available functions.

50 programs can be loaded and saved in memory (JOB), All programs can be easily recalled when using an Up/Down torch.

It is also possible to create different jobs sequences to be used on specific applications.

Simple selection of the MMA mode provides a choice of the electrode-type (basic, rutile, CrNi, Alu) setting, resulting in optimizing the weldability and parameters.

Weco Discovery 220T EVO Features:

Dynamic Arc.

The Dynamic Arc function automatically increases the welding current when the arc voltage decreases and vice versa. This controls the heat input to the work piece allowing for better arc control in situations such root pass on pipes

Quick Start.

The Q Start (Quick start) function speeds up the joining of 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 joint. 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.

Multitack.

The Multitack function reduces the heat output while joining two light gauge parts. A series of arc strikes at short time intervals allows the material to cool during the pause between one strike and the next and thus minimise its deformation. The ability to adjust the frequency of the arc strike makes it possible to adapt the arc to the welding speed and the joint geometry.

Quick Spot.

The Q-Start (Quick Spot) function reduces tacking times for light gauge sheet metal. The operator places the tungsten electrode on the work piece, thereby obtaining perfect control of the position of the join, once the electrode has been lifted the machine emits a very high intensity pulse with a very short preset time (from 0.01 Sec to 10 Sec). The pulse time varies depending on the type of  metal to be joined. In this way the material is tacked instantly with minimum heat transfer, leaving the metal white, clean and almost cold.

Supplied with  8Mtr PRO26 Flexi Neck – Air Cooled TIG Torch & 4 meter earth lead.
