TIG welding machineDiscovery 221AC/DC Evo

Discovery 221AC/DC Evo is a revolutionary state-of-theart 1Phase portable TIG AC/DC and MMA welding Inverter.

Ordinary steels, stainless steel and copper can be easily welded in TIG DC.

Discovery 221AC/DC 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.

The TIG AC welding is here optimized thanks to:
Extra Fusion , MIX AC/DC

The TIG DC welding is here optimized thanks to:
TIG PULSE up to 2,5Khz, TIG PULSE SYN, Dynamic Arc, Q-Start, Multi-Tack, Q-Spot.

Special functions

LOGO-TIG-SYN

TIG Pulsed SYN

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

TIG 2.5 kHz

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

LOGO-QUICK-START

Q-Start

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.

LOGO-MULTITACK

Multitack

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.

LOGO-DYN-ARC

Dynamic Arc

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.

LOGO-QSPOT

Q-Spot

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.

LOGO-MIX-ACDC

Mix AC/DC

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

LOGO-EXTRA-FUSION

Extra Fusion

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.
