TIG/MMA Superior TIG 311 DC HF/Lift inverter welding machine, 230-400V

This welding machine is a power source for arc welding, made specifically for TIG (DC) (AC/DC) welding with HF or LIFT strike and MMA welding with coated electrodes (rutile, acid, basic). The particular features of this welding machine (INVERTER), such as high-speed and precise adjustment, result in excellent quality welds. The inverter system of regulation at the power supply input (primary) also leads to a drastic decrease in the volume of both the transformer and the levelling reactance so that it is possible to build a considerably smaller, lighter welding machine, highlighting its advantages of easy handling and transport.

Main features

• TIG (HF or LIFT strike), TIG PULSE and MMA in direct current (DC) inverter welding machine, 250/300A. 3ph 400V power supply.
• VRD device for greater safety in welding operations in damp environments.
• This model operates in both pulsed (PULSE) and facilitated pulsed (EASY PULSE) modes, ideal for applications on thin thicknesses or easily deformable materials, using optimized minimum current arc strike (HF/LIFT).
• ThinSpot is an advanced function that allows spot welding in TIG of thin sheets in an easy, precise and rapid way. Particularly designed for working on stainless steel, it can also be used on Steel and Titanium.
• TIG regulations: "bi-level", start up/end current, spot welding time, pre/post gas, current up/down slope, balance DC, square wave frequency.
• MMA: Arc force and Hot start functions.
• Anti-stick device.
• Remote control and G.R.A. water cooling connector.
• Thermostatic, overvoltage, undervoltage, overcurrent, water cooling unit protections.
