This symbol accompanies important information concerning
the execution of the relevant operations.
Discovery 300 AC/DC is an advanced technology single-phase
welding power source for AC and DC TIG welding operations.
AC TIG functions are ideal for aluminum, 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 ignition selection located on the front panel, it
modifies the ignition according to electrode diameter.
−
Extra fusion function maximizes arc focusing for considerable thin
material in AC TIG welding.
−
Mixed AC/DC increases arc penetration for thick aluminum 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.
The welding modes and procedures available are those indicated in
the table.
