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

The JET TIG III 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 in 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, arc ignition occurs 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 contaminating the weld with tungsten, 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 combines the use of alternating current with pulse, enabling welding of very thin aluminum elements. Arc ignition occurs through contact of the electrode with the welded material.

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

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

• TIG AC HF – analogous function enabling aluminum welding with alternating current; ignition occurs without contact by means of 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, 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 welding with alternating current AC.

• PLASMA CUT - function enabling cutting of electrically conductive elements made of carbon and alloy steels, aluminum and its alloys, brass, copper, as well as cast iron

• MMA DC+ – In the MMA method, a coated electrode is used, consisting of a metal core covered with flux. An electric arc is generated between the end of the electrode and the welded material. Arc ignition occurs by touching the end of the electrode to the welded material. MMA DC+ means welding with positive polarity – more heat is generated in the material and less in the electrode.

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

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

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

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

• ARC IGNITION USING THE LIFT-ARC SYSTEM (2T and 4T)
• NON-CONTACT HF ARC IGNITION (2T and 4T)
• ARC IGNITION WITH REMOTE CONTROL PEDAL (2T and 4T)

  • HF – the device is equipped with an ionizer enabling non-contact arc ignition.
  • PRE and POST GAS – gas flow before and after welding.
  • UP and DOWN SLOPE – rise and fall of welding current.
  • PULS – pulse current function, mainly used for welding thin elements (even with thickness of 0.1 mm), metals with low melting temperature such as lead, or welding in forced positions. Other advantages of pulse welding include smaller heat affected zone, greater welding arc stability, greater penetration depth, and improved weld face appearance.
  • CUT – plasma cutting function.
  • HOT START – function increasing current at arc ignition, facilitating welding start.
  • ARC FORCE – function stabilizing the welding process by maintaining the welding arc voltage value regardless of its length and facilitating control over the amount of spatter.
  • VRD – Voltage Reduction Device – reduces the no-load voltage of the device’s secondary circuit. 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.
