Thanks to synergic settings, it is possible to automatically select welding parameters according to the diameter of the welding wire as well as the thickness and type of material.

The device features smooth adjustment of voltage and welding current and is equipped with an overload thermal protection system protecting integrated circuits from excessive overheating.

Thanks to the use of modern IGBT technology and high-quality components, the Welder Fantasy MULTI PERFECT BI-PULSE 251 devices are ideally suited for professional welding work in industries such as automotive, metal structures, and many others.

IGBT Technology - Insulated Gate Bipolar Transistor - is a modern technology based on bipolar transistors with an insulated gate. It combines the ease of control of field-effect transistors with the high breakdown voltage and switching speed of bipolar transistors. The use of IGBT technology significantly extends the reliable operation time of welding equipment.

AUTO - synergic settings - automatic adjustment of welding parameters such as voltage and welding arc current as well as wire feeder speed. The device automatically selects welding parameters according to the wire diameter and the thickness and type of material.

MIG/MAG - Gas-shielded arc welding is one of the most commonly used processes for manufacturing welded structures. The semi-automatic welding process consists of melting the edges of the welded object and the consumable electrode material with the heat of an electric arc burning between the electrode in the form of a solid wire and the welded workpiece, in a shield of inert or active gas.

MIG PULSE - an advanced form of welding that utilizes the best features of molten electrode material transfer to the welded workpiece. Unlike short circuits, pulsed welding does not produce spatter and does not pose a risk of cold laps. Welding positions in pulse mode are not limited, as they are derivatives of globular or spray transfer forms, and their use is significantly more efficient. Thanks to cooling of the spray arc process, pulsed MIG is able to extend the welding range, and the lower heat input does not cause burn-through of thin materials. MIG PULSE is one of the best welding processes for a wide range of applications and metal types.

MIG DOUBLE PULSE - When welding using the MIG/MAG method with double pulse, a high level of weld face appearance (scale effect) is achieved. Additionally, the use of automatic wire feeding improves welding efficiency. The MIG/MAG double pulse method allows adjustment of current pulsation (pulse balance) and wire feed speed. This enables improvement of weld appearance. During MIG/MAG double pulse welding, current pulses occur in two ranges. The sequential system of our devices automatically combines two pulse levels: hot and cold.

The benefits of using the MIG/MAG double pulse method are:

• MIG/MAG double pulse welding is faster than TIG welding.
• MIG/MAG double pulse welding achieves high aesthetics similar to TIG welding.
• MIG/MAG double pulse welding causes less distortion than TIG welding.

FCAW - Thanks to the polarity change function, it is possible to weld without shielding gas using self-shielded FCAW wire. This method uses self-shielded flux-cored wire (in all positions) for welding steels of normal and increased strength not exceeding 510 MPa. The self-shielded wire can be used in single- and multi-layer welding processes, using power sources with both flat and drooping characteristics. The wire is intended for general production work, also in field conditions, and for welding structures where impact strength requirements are not specified. Welding current DC(-).

TIG MIX(AC+DC)- the TIG MIX (AC+DC) function enables welding with mixed current AC + DC. In a single cycle, a transition occurs between alternating current AC and direct current with negative polarity DC(-). This cycle repeats throughout the entire welding process. Mixed current welding is particularly useful when joining elements of different thicknesses. Noise emission is also reduced compared to AC welding.

TIG DC HF - In order to completely eliminate the possibility of tungsten contamination of the weld, it is recommended that the electrode does not touch the welded element; for this purpose, non-contact arc ignition is used by means of high-frequency discharges generated by the ionizer built into the device.

TIG DC PULSE HF - non-contact HF ignition using the ionizer in TIG DC PULSE mode.

TIG AC HF - an analogous function enabling aluminum welding with alternating current, ignition occurs non-contact via high-frequency current generated by the ionizer.

TIG AC PULSE HF - a function enabling welding of thin aluminum elements. Non-contact ignition thanks to the use of an ionizer.

MMA - a method in which a coated electrode is used, consisting of a metal core covered with flux coating. The welder feeds the electrode as it melts into the welded object so as to maintain an arc of constant length while simultaneously moving its melting end along the welding line. The device enables welding with all types of electrodes, e.g., basic, cellulose, rutile, or acidic.

MMA VRD - the VRD (Voltage Reduction Device – module reducing the idle (no-load) voltage of the device’s secondary circuit) function available in MMA mode. It increases safety and reduces the risk of electric shock. The function switches the welding power supply off and on when resistance between the electrode tip and the welded element is detected during welding.

ADDITIONAL FUNCTIONS:

• Waveform selection - the device allows selection among the following AC waveform shapes: rectangular, sinusoidal, triangular, ascending triangular, descending triangular, trapezoidal.

• Inductance adjustment in MIG/MAG method. Properly selected welding inductance contributes to reducing the amount of spatter. It depends on the diameter of the welding wire, the shielding gas used, the current intensity, and the welding position. Reducing inductance makes the arc more stable and concentrated, while increasing it contributes to the formation of a more fluid weld pool and reduces the amount of spatter. Proper selection is characterized by a stable arc, uniform transfer of liquid metal droplets, maintaining a constant weld pool size, and a characteristic repetitive sound without spatter and explosions.
• Brazing - the device enables brazing, mainly used in the automotive industry for joining galvanized sheets.
• SPOT spot welding - a timed welding function used for tack welding elements, enabling uniform weld seam length.
• Arc ignition via: 2T - two-stroke, 4T - four-stroke, S-2T - special two-stroke (possibility of setting additional parameters), S-4T - special four-stroke (possibility of setting additional parameters).
• PRE GAS - adjustment of shielding gas flow time before welding.
• POST GAS - adjustment of shielding gas flow time after welding.
• HOT START - a function facilitating welding start in MMA mode. At the moment of arc ignition, the welding current is temporarily increased to heat the material and electrode at the contact point and to properly shape penetration and weld face in the initial phase of welding.
• ARC FORCE - a function stabilizing the arc by maintaining the welding arc voltage value regardless of its length and facilitating control over the amount of spatter.
• VRD - reduced idle voltage.
