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.
6. CONNECTION TO THE MAINS
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 210P are adapted to cooperate with a network of 230V 50 Hz fused 16A by time-delayed action. Power supply should
be stable, with no voltage drops
3. The device is equipped with a power cord. Before connecting, make sure the power switch (15) 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 (8) and (9) 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.
