MIG-MAG/TIG (DC)/MMA Supermig 350i inverter welding machine, 3ph, 230V/400V,Telwin

• It is particularly suitable for light metalwork fabrication and in body shops, for welding galvanized plates, high stress stainless steel and aluminium. SYNERGIC operation ensures fast and easy welding parameter setting, always guaranteeing high arc control and welding quality.
• The welding machine can be used for TIG welding in direct current (DC), with arc striking upon contact (LIFT ARC mode). It welds all types of steel (carbon, low- and high-alloy) and heavy metals (copper, nickel, titanium and their alloys) with a gas shield of pure (99.9%) Ar or, for special uses, with an Argon/Helium mix. It can also be used for MMA electrode welding in direct current (DC) using coated electrodes (rutile, acid, basic).

Key features

• MMA and TIG DC-Lift, electrode inverter welding machine, 270A. 3ph 230/400V power supply.
• Particularly resistant to dirt and dust thanks to the special construction of the ventilation system which, following a dedicated tunnel, preserves the electronic components, guaranteeing a longer life.
• The graphic display allows a clear view of the main welding parameters and product settings.
• Electrode welding is possible in both direct and pulse current modes. The pulse mode (MMA Pulse) is recommended for basic electrodes and positional welding and guarantees less spatter and rework and higher weld quality.
• The GOUGING function is available with carbon electrodes.
• Light weight and compactness also ensure easy portability to all locations, both indoors and outdoors.
• Can be used with 300mm reels, max. 15 kg

MIG-MAG
- Operating modes:
- manual;
- synergic;
- Wire speed, welding current and voltage shown on the display.
- Operation selection 2T, 4T, Spot.

• 2T: welding begins when the torch push-button is pressed and ends when the push-button is released.
• 4T: welding begins when the torch push-button is pressed and released, and ends only when the torch push-button is pressed and released a second time. This mode is useful for long welding operations.
• Spot welding mode: used for MIG/MAG spot welding with control of welding duration.

TIG
- Start LIFT: The electric arc is struck by moving the tungsten electrode away from the piece to be welded. This strike mode causes less electrical-radiation disturbance and reduces tungsten inclusions and electrode wear to a minimum.
- Welding voltage and current shown on an LCD screen.

MMA
- Operating modes:
- Direct current MMA;
- Pulse current MMA;
- Arc force (DYNAMIC ARC) and welding current adjustment. This helps maintain a stable arc even in difficult conditions, such as dense welds. With the Arc Force function, the inverter automatically adjusts the current depending on the length of the arc. If the arc accidentally touches the workpiece, the current increases, so it does not stick. If the two are too far apart, the current will be reduced and the arc will not extinguish.
- Hot Start function helps to ignite the arc more easily by automatically increasing the current at the beginning of the welding process. This can be especially useful for difficult-to-ignite electrodes. Facilitates arc ignition for materials that are too cold or too thick. 
- VRD device for greater safety. Enabling/disabling the “Voltage Reduction Device” for a safe start at low voltage.
- The Anti-Stick function prevents the electrode from sticking to the workpiece, reducing the current connected to the electrode when it detects sticking. This makes it easier to remove the electrode and reduces the risk of overheating.
