Welder Fantasy is a brand created by FACHOWIEC in 1991. TIG/MMA inverter welders, MIG/MAG semi-automatic welding machines, plasma cutters and other Welder Fantasy equipment have been recognized by thousands of workshops and enterprises in Poland and abroad for many years. The Welder Fantasy brand is:

• The highest quality of devices,
• reliability,
• high working parameters,
• A leader on the Polish market.

DEVICE FEATURES:

• compact design,
• IGBT transistors,
• efficiency 60%,
• easy-to-use control panel,
• very wide selection of welding functions.

The device enables welding using the following methods:

• TIG DC lift-arc - In the TIG (Tungsten Inert Gas) method, the electric arc is ignited in a shield of inert gas (argon), between the welded element and a non-consumable electrode made of pure tungsten or tungsten with additives. In the TIG lift-arc mode, the arc is ignited when the electrode contacts the workpiece. In TIG DC mode, the current is constant.
• 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 workpiece; for this purpose, contactless arc ignition is used using high-frequency discharges generated by the ionizer built into the device.
• TIG DC PULS lift-arc - the arc is ignited by contacting the electrode with the material being welded, the pulse function allows welding of thin elements through periodic changes in current intensity.
• TIG DC PULS HF - non-contact HF ignition with an ionizer in TIG DC PULS mode
• MMA DC+ - The MMA method uses a coated electrode, consisting of a metal core covered with a coating. An electric arc is generated between the end of the electrode and the material to be welded. The arc is ignited by touching the tip of the electrode to the workpiece. MMA DC+ means welding with positive polarity - more heat is generated in the material and less in the electrode.
• MMA DC- - the difference between MMA DC+ is that the polarity in the MMA DC - mode is negative, so the heat distribution is reversed - more heat is generated at the electrode and less in the welded material.
• MMA VRD DC+ - available in the MMA DC+ mode, the VRD function (Voltage Reduction Device - a module that reduces the idle voltage of the secondary circuit of the device. Increases safety and reduces the risk of electric shock. The function turns off and on the welding power supply when the resistance is measured during welding between the ends of the electrode - the welded element.
• MMA VRD DC- - available in the MMA DC- mode, the VRD (Voltage Reduction Device) function works in the same way as MMA VRD DC+, the difference is in the negative polarity.

PANEL FUNCTIONS:

• HOT START - a function that increases the current when the welding arc is ignited, making it easier to start welding.
• ARC FORCE - short-circuit current adjustment - shortening the arc length is accompanied by an increase in the welding current, which stabilizes the arc regardless of length fluctuations.
• HF - the device is equipped with an ionizer that allows you to look at the welding arc without contact.
• PRE and POST GAS - gas flow before and after welding.
• UP and DOWN SLOPE - rising and falling welding current.
• PULSE - pulsating current welding mode.
• VRD - Voltage Reduction Device - reduces the no-load voltage of the secondary circuit of the device. Increases safety and reduces the risk of electric shock.
• PFC - Power Factor Correction - increasing the power factor to a value as close as possible to 100% in order to reduce power losses in transmission lines.
• 2-STEP and 4-STEP,
• non-contact HF ignition and by rubbing LIFT,
• the possibility of connecting a remote control - a control pedal, a handle with a potentiometer,
• double-function ADJUST knob (coarse and fine adjustment), and others, described in the user manual.
