1.1 INTRODUCTION
Discovery 221AC/DC Evo is an advanced technology single-phase welding power source for AC and
DC TIG welding operations.
Discovery 300AC/DC Evo is an advanced technology three-phase welding power source for AC and
DC TIG welding operations.
AC TIG functions are ideal for aluminium, magnesium and related alloys welding.
Mild steel, stainless steel and copper can be easily welded in DC TIG.
AC TIG welding is optimized thanks to:
Synergic arc strike can be selected by the user interface according to tungsten electrode diameter.
Extra fusion function maximizes arc focusing for considerable thin material in AC TIG welding.
Mixed AC/DC increases arc penetration for thick aluminium plates.
Pulsed AC TIG mode which prevents the risk of deformation of the workpiece in the case of prolonged
welding operations.
Up to 4,00mm diameter electrode welding is possible in MMA.
The fan is turned on only during welding, at the end of the welding process it remains on for a fixed
period of time according to welding conditions.
The fan is nonetheless controlled by specific thermal sensors that guarantee a correct cooling of the
machine.
Accessories/ancillary devices that can be connected to the unit:
-
manual remote control for remote adjustment of the welding current.
-
foot-pedal remote control for TIG torch arc striking and remote adjustment of welding current.
-
UP/DOWN torch or torch with potentiometer.
- liquid cooler for TIG torches.
