16. Brief description
• Innovative and compact design
• Protective visor on the control panel
• Digital ammeters and voltmeters are standard fittings, with pre-setting of welding current and
saving of the latest value
• Digital control of all welding parameters
• welding programs can be stored in the memory
• Self-diagnosis device
• Exceptional characteristics for TIG and MMA welding with all types of electrode, excluding
cellulose
• Overheating thermostatic protection
• Automatic compensation for mains voltage fluctuations within ±15%
• Safety barrier against excess voltage from mains
• “Energy Saving” function to operate the power source cooling fan and the torch water cooling
only when necessary
• IP 23 S protection class and dust-proof electronic components, allow operation in the toughest
work environments
• Low absorbed current consumption
• Using up/down TIG torches makes it possible to adjust the welding parameters and programs
stored in the memory from the torch
• Possibility of activating a VRD (Voltage Reduction Device) that makes it possible to use the ma-
chine in environments in which the risk of electric shock or electrocution caused by arc welding is
much higher due to the presence of water, damp, or heat.
