ThesechnoloIGBT – Insulated Gate Bipolar Transistor – gia. is a modern technology based based on Bipolar transistors with an isolated gate. It combines the ease of control of transistors p ol wire with high breakdown voltage and switching speed tranzistors bipolar. The use of IGBT technology has the effect of significantly extending the reliable operation of welding equipment .

Welder Fantasy 3-in-1 semi-automatic welding machine OVER 250 is a microprocessor-based welding source based on IGBT technology, suitable for welding carbon steel, stainless steel, acid-resistant steel, copper, brass, magnesium, titanium and all aluminum alloys. As the first on the Polish market, the OVER TIGMIG 250 allows welding with MIG/MAG, TIG AC/DC and MMA methods. The top-of-the-line device sets new standards among AC/DC welding machines, and the user-friendly control panel ensures selection of all necessary working parameters. The integrated design with a cooler and welding carriage enables efficient and convenient operation.

Welder Fantasy 3-in-1 OVER TIGMIG 250 P/4 welder allows welding methods:

MIG/MAG – Gas shielded arc welding is one of the most widely used processes for manufacturing welded structures. The semi-automatic welding process involves melting the edges of the workpiece to be welded and the fusible electrode material with the heat of an electric arc glowing between an electrode in the form of a solid wire and the workpiece to be welded, in an inert or active gas shield.

FCAW – Thanks to the polarity change function, it is possible to weld without shielding gas, with FCAW self-cored wire. It is a method using self-cored wire for welding (in all positions) of normal and higher strength steels, not exceeding 510 MPa. Self-shielded wire can be used in single and multi-layer welding processes, using both flat and falling current sources. The wire is designed for general production work, including in field conditions, and for welding structures that do not have impact requirements. DC(-) welding current.

AUTO – synergistic settings – automatic adjustment of welding parameters such as welding arc voltage and amperage and wire feeder speed. The user selects on the panel the thickness of the welding wire and the type of metal to be welded, to which the device automatically adjusts the welding parameters.

TIG DC PULS lift-arc – arc ignition is performed by contacting the electrode with the material to be welded, the pulse function allows welding thin parts by periodically changing the current.

TIG DC PULS HF – non-contact HF ignition using an ionizer in TIG DC PULS mode.

TIG DC lift-arc – In the TIG (Tungsten Inert Gas) method, an electric arc is struck in a shield of inert gas (argon) between the workpiece and an infusible electrode made of pure tungsten or tungsten with additives. In TIG lift-arc mode, the arc is struck when the electrode comes into contact with the workpiece. In TIG DC mode, the current is constant.

TIG DC HF – In order to completely eliminate the possibility of contamination of the weld with tungsten, it is recommended that the electrode does not touch the workpiece being welded; for this very purpose, non-contact arc ignition is used using high-frequency discharges generated by the built-in ionizer.

TIG AC PULS lift-arc – welding in this mode is a combination of AC and pulse application, which allows welding of very thin aluminum parts. The arc is engaged by contact between the electrode and the material to be welded.

TIG AC PULS HF – a function that allows you to weld parts made of aluminum with a small thickness. Non-contact ignition thanks to the use of an ionizer.

TIG AC lift-arc – a function that allows the welding of aluminum through the use of alternating current, which has the function of cathodic cleaning when welding aluminum. With the ability to set the parameter AC BALANCE, or AC balance, it is possible to adjust the ratio of the duration of its phases in relation to each other

TIG AC HF – analogous function that allows welding of aluminum with alternating current, the ignition occurs non-contact through high-frequency current generated by the ionizer

MMA DC+ – The MMA method uses a covered electrode, consisting of a metal core covered with a lagging. An electric arc is produced between the end of the electrode and the material to be welded. The arc is ignited by touching the end of the electrode to the material to be welded. MMA DC+ means welding with positive polarity – more heat is released in the material and less in the electrode.

MMA DC- – the difference with MMA DC+ is that the polarity in the MMA DC- mode is negative, so the heat distribution is reversed – more heat is released on the electrode and less in the welded material.

Versatility is undoubtedly one of the biggest advantages of OVER TIGMIG equipment. The possibility of pulsed current welding in TIG mode (with full pulse modulation) gives users unlimited possibilities when welding aluminum alloys, carbon steels, stainless steels
and acid-resistant steels.

The device is equipped with a EURO type socket. It allows welding with EURO MIG/MAG handles and EURO TIG type handle. Additional control plug socket, allows you to connect an additional external control to the device (e.g. control pedal, Spool Gun handle control).

* HF – the device is equipped with an ionizer, which allows a non-contact look into the welding arc.

* PRE and POST GAS – gas outflow before and after welding.

* UP and DOWN SLOPE – rising and falling welding current.

* PULSE – pulsed current function, is mainly used for welding thin parts (even 0.1mm thick), metals with low melting point such as lead, or welding in forced positions. Other advantages of pulsed current welding are a smaller heat affected zone, greater stability of the welding arc, and greater depth of fusion and improved appearance of the weld face.

* Inductance adjustment in the MIG/MAG method – Properly adjusted welding inductance contributes to reducing spatter. It depends on the diameter of the welding wire, the shielding gas used, the current and the welding position. Decreasing the inductance makes the arc more stable and concentrated, while increasing it contributes to a smoother weld pool and fewer spatters. Properly selected is characterized by a stable arc, even transfer of liquid metal droplets, maintaining a constant size of the weld pool, and the characteristic repetitive sound without splatter and explosions.
* ARC FORCE – a function that stabilizes the welding process by maintaining the welding arc voltage value, regardless of its length, and facilitates control over the amount of spatter.

* BURN BACK – a function that prevents the electrode wire from sticking to the current tip, by temporarily ejecting the wire after the welding process is completed. The device allows you to set the burn back function time in the range of 0-10s.

* HOT START – a function that facilitates the start of welding in both MMA and MIG/MAG modes. At the moment of arc ignition, the welding current is temporarily increased in order to warm up the material and electrode at the point of contact and to properly shape the fusion and the weld face in the initial phase of welding.

* PRE GAS – control of shielding gas discharge time before welding,

* POST GAS – adjustment of shielding gas discharge time after welding.
