MIG-MAG/FLUX/BRAZING/MMA/TIG DC-Lift inverter welding machine, 3Ph Supermig 500I XD, 230V/400V

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).

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. A higher value determines a hotter welding bath. Settings from -50% (low reactance machines) to +50% (high reactance machines). Factory value: 0%.
- Trailing wire ramp: Use to adjust wire feed rate as welding starts, in order to optimise arc strike. Settings from 20 to 100% (start in % of full capacity speed). Factory value: 50%.
- Wire speed correction: 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. It increases or decreases the wire feed speed according to the display. Settings from -5 to +5m/min. Factory value: 0 m/min.
- 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. Use to adjust the wire burn-back time when welding is stopped. Settings from -10% to +10%. Factory value: 0%.
- 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. Use to adapt the protective gas outflow starting from when welding is stopped. Settings from 0 to 10 seconds. Factory value: 1 sec.

The ATC (Advanced Thermal Control) technology

The Made in Telwin ATC technology is designed for use in specific sectors such as, for example, car bodywork where the materials (with thin materials measuring from 0.5-0.8 mm) are extremely sensitive to deformation caused by the temperatures reached during welding operations. 

The ATC technology makes it easy to achieve excellent standards of welding on thin materials thanks to state-of-the-art control of the arc.

Advantages

• Easy welding of thin materials
• Decreased deformation of material
• Extremely stable arc even whenworking with low currents
• Rapid and accurate tack welding
• Easier coupling of spaced sheets
• Excellent results on steel, aluminium and during brazing operations

MIG/MAG welding is a shielded gas arc welding process in which a continuously fed wire serves as welding material instead of a consumable electrode. The shielding gas in the welding gun protects the scar pool from oxygen and moisture in the air. The advantage of MIG/MAG welding is that the welding speed is higher than that of conventional arc welding and the welding seams are cleaner. There are two types of MIG/MAG welding: active gas (MAG) and neutral gas (MIG) welding. During active gas welding, the protective gas contains carbon dioxide, while during neutral gas welding, argon or an argon-helium mixture is used.

Advantages

• It involves less frequent wire replacement, which results in higher productivity
• Reduced waste and smoke, minimized material wastage
• The arc and the welding process are clearly visible
• Operating mode; manual and synergic
• 35 pre-set synergic curves
• Wire speed and welding voltage and current shown on an LCD screen
• Operation selection 2/4 times, spot

  • 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: wire up slope, electronic reactance, wire burnback time, post gas
• ATC technology
• Wire feed unit adjustments: manual wire feed, weld seam adjustment, wire feed speed (MAN mode) and welding power (SYN mode)
• Possibility of connecting a semi-automatic type wire feeder unit (CV).

MMA 

MMA (Manual Metal Arc) welding is an arc welding process, also known as manual metal arc welding or stick welding. This method uses a consumable electrode (welding rod) that melts simultaneously with the arc and serves as a filler material in the weld seam. MMA welding is often used in outdoor applications because it is less sensitive to wind and dirt than other welding methods. It is suitable for a wide range of metals, including steel and iron-based alloys, and is well suited for thicker materials and structural work.

• Direct and pulse current (MMA PULSE) operation

- Arc force: 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: it 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.
- Anti-stick: 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.
- VRD device for greater safety. Enabling/disabling the “Voltage Reduction Device” for a safe start at low voltage.
- Wire speed and welding current shown on an LCD screen.

TIG

TIG (Tungsten Inert Gas) welding is an arc welding method where the welding arc is created between a tungsten electrode and the workpiece in an inert (unreactive) gas environment such as argon or helium. This method is often used in situations where high precision and quality of the weld seam is required, such as when welding stainless steel or aluminum. TIG welding enables precise and clean welding of thin materials and is widely used in aerospace, automotive and artistic applications.

• LIFT DC strike and welding voltage and current shown on LCD screen. 

LIFT strike: 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.

GOUGING

• Gouging function with gouging voltage and current shown on LCD screen.

This procedure consists of using carbon gouging electrodes, covered with a copper film for current transfer. The metal is fused by the electric arc between the end of the electrode and the workpiece. The molten metal is blown by compressed air. The oxygen contained in the compressed air oxidises the molten metal and limits it adherence to the workpiece. The gouging current should be adjusted based on the diameter of the electrode used.
