    2. Description of this welder The welder adopts rectifier designed with advanced inverter technology. The advent of inverter arc welding machine derives from inverter power theory and devices. The inverter arc welding power uses high-power device IGBT field-effect transistor to turn the working frequency of 50/60Hz to high frequency (such as 100KHz or higher).

  • Page 12 Start current - current appearing in the circuit after pressing the button in the grip handle. The higher the initial current, the easier it is to ignite the arc. However, when welding thin sheets, too high an initial current can lead to the burning of the sheet. In some welding modes, the current does not increase in order to heat the welded element.

    2T / 4T - modes of source operation control. In the 2T time, pressing the TIG torch button starts welding, releasing the welding end button. In the 4T, pressing and releasing the button starts welding, to finish it, press and release the button again. Four-stroke is mainly used when making long welds, as it does not require holding the button on the handle during operation at all times.

    If the device is stored or transported in low temperatures, the device should be brought to the right temperature before starting work !!! The ends of the welding cables should be connected to the sockets (21) and (23) on the front panel, so that the polarity of the electrode is on the electrode holder.

    - Do not touch the electrode while holding the button on the handle. The high voltage of the ionizer and the unloaded voltage then occurring at the electrode can cause electric shock 9、Routine maintenance Warning： All the maintenance and repair jobs must be carried out when the power is cut-off completely.

  • Page 18: Precautions Before Repairs

    10、Precautions before repairs Warning A haphazard experiment and imprudent repair may lead to expansion of fault area, making formal repair more difficult. The exposed part of the welder in energization carries high voltage that may lead to hazards and any direct or indirect touch with it will result in electric shock accident. In serious case death may occur If in the warranty period the user carries out an erroneous examination and repair of any fault in the welding and cutting power without permission, the free maintenance warranty offered by the...
