Level of security

IP specifies the extent to which the device is resistant to entering of solid impurities and water. IP23 means that the device is suitable for use in
confined spaces and is not suitable for use in the rain.

5. CONSTRUCTION AND OPERATION

The basis for the construction of the power conversion electronics welders are made in IGBT technology for working in the frequency range above 200
kHz. The principle consists of a single-phase rectified voltage to the power supply voltage, conversion of the resulting DC voltage to a square wave
high frequency voltage transformation in the range required by the welding process and re-erection of the resulting voltage on the DC voltage. The
welding device is equipped with a compensation system power supply, allowing them to operate with voltage fluctuations in the mains to 10%.

6. CONNECTION TO THE MAINS

1. A device to be used only in a single-phase, three-wire, with earthed neutral.
2. The inverter units DIGITIG 200AC / DC MULTIPRO are adapted to cooperate with 230V 50Hz fused 25 A time-delayed action. Power supply
should be stable, with no voltage drops.
3. The device is equipped with a power cord and a plug. Before connecting, make sure the power switch (7) is in the OFF position (off).

7. PREPARING THE APPLIANCE FOR OPERATION

For storage or transport devices in freezing temperatures before the start of work to bring the device to an appropriate temperature
!!!
7.1 MMA
Welding the wire ends to terminals (1) and (5) located on the front panel so that the electrode holder was appropriate for the electrode pole. The
polarity of the wiring depends on the type of welding electrodes used and is given on the electrode packaging. Ground cable terminal must be
carefully mounted on a welded material. Plug the device into a power outlet 230V 50Hz.
