This top-class device sets new standards among AC/DC welding machines, and the user-friendly control panel ensures the selection of all necessary operating parameters.

The JET TIG II AC/DC 250 welding machine enables welding using the following methods:

• TIG DC PULS lift-arc - arc ignition occurs through contact of the electrode with the welded material, the pulse function allows welding of thin elements through periodic changes of current intensity.

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

• TIG DC lift-arc - In the TIG method (Tungsten Inert Gas), the electric arc is ignited in an inert gas shield (argon) between the welded element and a non-consumable electrode made of pure tungsten or tungsten with additives. In TIG lift-arc mode the arc is ignited when the electrode touches the welded element. 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 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 AC PULS lift-arc - welding in this mode is a combination of alternating current and pulse, which enables welding of very thin aluminium elements. Arc ignition occurs through contact of the electrode with the welded material.

• TIG AC PULS HF - a function enabling welding of aluminium elements with small thickness. Non-contact ignition thanks to the use of an ionizer.

• TIG AC lift-arc - a function that allows welding aluminium by using alternating current which performs the cathodic cleaning function during aluminium welding. Thanks to the possibility of setting the AC BALANCE parameter, it is possible to adjust the ratio of the duration of its phases relative to each other.

• TIG AC HF - an analogous function enabling aluminium welding with alternating current; ignition occurs without contact through high-frequency current generated by the ionizer.

• TIG AC + DC - the ADVANCED AC function enables welding with mixed AC/DC current. In a single cycle there is a transition 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 welding with alternating current AC.

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

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

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

• MMA VRD DC- - available in MMA DC- mode, the VRD function (Voltage Reduction Device) operates analogously to MMA VRD DC+, the difference being negative polarity.

For all TIG methods it is possible to use the following welding modes:

• ARC IGNITION THROUGH LIFT-ARC SYSTEM (2T and 4T)
• NON-CONTACT HF ARC IGNITION (2T and 4T)
• ARC IGNITION BY REMOTE CONTROL PEDAL (2T and 4T)

    • SINE - sinusoidal waveform recommended for welding pure aluminium 99.999%
  • AC/DC EASY SETUP - possibility to use programmed factory settings.
  • NORMAL SETUP - welding parameters set according to individual needs.
  • HOT START - function increasing current during arc ignition, facilitating welding start.
  • HF - the device is equipped with an ionizer which enables non-contact arc ignition.
  • PRE and POST GAS - gas flow before and after welding.
  • UP and DOWN SLOPE - increase and decrease of welding current.
  • PULSE - pulsed current function mainly used when welding thin elements (even 0.1 mm thick), metals with low melting temperature such as lead, or welding in forced positions. Other advantages of pulsed current welding include smaller heat-affected zone, greater arc stability, deeper penetration and improved weld bead appearance.
  • ARC FORCE - function stabilizing the welding process by maintaining arc voltage regardless of its length and facilitating control over the amount of spatter.
  • 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.
