    Discovery 200AC/DC Evo Cod. 006.0001.2320 13/02/2023 V.1.0 ENGLISH 1.1 INTRODUCTION Discovery 200 AC/DC Evo is an advanced technology single-phase welding power source for AC and DC TIG welding operations. AC TIG functions are ideal for aluminium, magnesium and related alloys welding. AC TIG welding is optimized thanks to: Synergic arc ignition selection located on the front panel, it modifies the ignition according to electrode diameter. Advanced Soft AC-Square Waveform for outstanding welding quality through faster welding speed, bet- ter pool control and noise reduction. Mild steel, stainless steel and copper can be easily welded in DC TIG. Slow Pulse (0.1Hz-5.0 Hz) and Fast Pulse (5.0 Hz-250 Hz) are available in TIG DC. Special HF control provides 100 % rapid and precise arc ignition. Up to 3,25 mm diameter electrode welding is possible in MMA. Accessories/ancillary devices that can be connected to the unit: - Overcut device to protect the power source from power supply voltage spikes that could damage the electrical components.

  • Page 29 Discovery 200AC/DC Evo Cod. 006.0001.2320 13/02/2023 V.1.0 ENGLISH - FINAL CURRENT ○ During electrode welding the parameter makes it possible to obtain a uniform deposit of filler ma- terial from the start to the end of the welding process, closing the deposition crater with a current such as to deposit a final droplet of filler material. ○ The value of this parameter can be set as a percentage of the welding current or as an absolute value expressed in Amperes. ○ The parameter is displayed but it is not used during the welding process when the following set- ting is present: MULTI TACK = ON ○ By keeping the torch trigger pressed during the 3rd time, the crater filler current is maintained thereby ensuring optimal crater filling, until the post gas time is started by releasing the torch trig- ger (4th time). - POST GAS TIME ○ Time of post gas delivery when the welding arc is extinguished. - Consequences of a higher value: • More effective pickling (improved appearance of workpiece at the end of the welding pass).

The voltaic arc ignites without touching the weld workpiece. • LIFT-ARC: This type of arc blow is derived from a short low-amperage circuit (to avoid elec- trode damage) that the operator created between the electrode tip and the workpiece and the consequent rise of the electrode tip that maintains the current flow by creating the so-called electric arc. It is advisable to use LIFT-ARC priming in applications such as maintenance of machinery in operation, welding close to printed circuits or soldering near computers.

  • Page 35 Discovery 200AC/DC Evo Cod. 006.0001.2320 13/02/2023 V.1.0 ENGLISH - AC INVERSION FREQUENCY ○ The frequency in TIG AC is the number of inversions by DC + to DC- as a unit of time (T1) and adjusted in Hertz (Hz). The reduction in the frequency value of the electric arc inversion tends to widen its size, therefore it is advisable to use low frequencies for the welding of relatively large thicknesses or for filling passes in multipass bevels. Conversely, in increasing the inversion fre- quency value, the arc size tends to decrease and therefore increases the concentration of the pool and the precision of the welding. It is therefore advisable to use high values of frequency for the welding of very thin thickness or for facings on edges of moulds - Consequences of a higher value: • Arc concentration. • Reduction of heat-affected zone. • Slower melt speed.

The following figure shows graphs with waves with different AC balance values: “0” BALANCE represents the optimum ratio between “Cleanliness and Penetration” “+” BALANCE represents the curve of the current curve with an AC Balance with a positive value (cleaner); in this case the percentage of the positive wave is greater than the negative one. “-” BALANCE represents the curve of the current with a negative value AC balance (more penetration) in which it can be seen that there is a low percentage of positive wave when compared with the negative. - Consequences of a higher value: • Greater weld penetration. • Less cleanliness.

    Discovery 200AC/DC Evo Cod. 006.0001.2320 13/02/2023 V.1.0 ENGLISH 11.4 EXPORTING/IMPORTING JOBs (through a USB memory stick) By using a USB memory stick, the JOBs saved on the panel can be exported and imported into another panel. When a USB memory stick is connected, the JOB MENU will display the items related to the importing and exporting procedure. WARNING! The JOBs are exported to the USB memory stick with the name of the location where they are saved on the panel. If the file names of the JOBs saved onto the USB memory stick are changed by using a PC, after they are imported into the destination panel, they will still be saved in their original location. This means that, if the destination panel already contains JOBs saved in the same location as those exported to the memory stick, they will be overwritten. We recommend not to change the name of the files exported to the USB memory stick. The file extension (.bin) must never be changed.
