MIG-MAG/FLUX/BRAZING/MMA/TIG DC-lift and GOUGING Supermig 350i Pack 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

• MIG-MAG/FLUX/BRAZING/MMA and TIG DC-Lift multiprocess inverter welding machine.
• With 4 roller wire feeder
• Can be used with 300mm reels, max. 15 kg
• Flexibility of use with different materials (steel, stainless steel, high-strength steel, aluminium, etc.) and wide variety of fields of application (industry, metalwork, construction, etc.).
• 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 fast SYNERGIC adjustment of the welding parameters thanks to the "ONE TOUCH" technology, makes the product very easy to use. Just set the material thickness and start welding.
• The intelligent and automatic control of the arc, moment by moment, maintains high welding performance in all working conditions, with different materials and/or gases.
• The operator can also intervene manually along the arc length: this adjustment means the weld seam can be modified according to the welder's style.
• The graphic display allows a clear view of the main welding parameters and product settings.
• The ATC technology, made by Telwin, allows excellent welds on thin surfaces to be obtained with great ease thanks to advanced arc control. The particular instantaneous control of the welding arc and the ultra rapid correcting of parameters minimize current spikes, something that is characteristic of Short Arc transfer procedures, to the advantage of a low thermal load on the piece to be welded. The result, on the one hand, is reduced deformation of materials and, on the other, a fluid and accurate transfer of the weld material and the creation of a welding seam that is easy to model.
  Advantages:
  - easy welding of thin materials;
  - decreased deformation of material;
  - stable arc even when working with low currents;
  - rapid and accurate spot welding;
  - easier coupling of spaced sheets.
• 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.
• High energy saving.
• Backlit LCD display.

MIG-MAG
- Operating modes:
- Manual;
- Synergic;
- 35 pre-set synergic curves
- LCD display of wire speed, welding voltage and current
- Selection of 2T/4T time operation and 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.

Adjustments:
- Electronic reactance: Adjusting the reactance during MIG/MAG welding allows you to fine-tune the inductance of the welding circuit. By adjusting the reactance, the welder can optimize the behavior of the welding arc when welding different material thicknesses and types, improving the quality of welding and facilitating the welding process.
- Wire upslope: This setting allows you to gradually increase the speed of the welding wire at the beginning of welding. This helps reduce welding errors such as excessive penetration or spatter when the arc is struck, ensuring a smoother start and transition in the welding process.
- Wire burnback time setting: This setting controls the amount of time the wire can "burn back" after welding is complete before it automatically stops. Setting the proper burnback time ensures that the wire does not burn back too short, making it easier to start the next welding cycle.
- Post-gas setting: This function controls the amount of time that shielding gas continues to flow after welding is completed to protect the still-hot weld from airborne contaminants until it cools down.
- ATC
- Adjustments from the wire feeder unit: manual wire feed, weld bead adjustment, wire feed speed (MAN mode) and welding power (SYN mode);
- Possibility of connecting semi-automatic wire feeder units (CV).

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.

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 VRD function allows to decrease the output voltage, increasing the operator’s safety when working in humid or particularly dusty environments.
- 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.

GOUGING

OTHER
- Setting the metric or UK system.
- Possibility of connecting a semi-automatic type wire feeder unit (CV).

PROTECTION
- Thermostatic protection: A heat-sensing system that shuts down the machine if the temperature rises too high, preventing overheating.
- Protection against accidental short-circuits caused by contact between torch and earth.
- Protection against irregular voltage (power supply voltage too high or too low).

STANDARD ACCESSORIES
- MIG torch
- Return cable complete with earth clamp
