8. protection against overheating
The power source is equipped with a thermal overload protection switch. When the temperature of the welding device is too high, the security
welding current is shut off and the LED will overheat indicator (1). After falling temperature will automatically reset the circuit breaker.
9. WELDING coated electrodes (MMA)
9.1. Preparing for operation
Welding the wire ends to terminals (5) and (6) located on the front panel so that the electrode holder was appropriate for the electrode pole. The
polarity of the welding wire used depends on the type of the electrode and is fed to the packaging electrode terminal of the second duct must be
carefully mounted on the welded material. Plug the device into a power outlet 230V 50Hz.
9.2. Setting the welding parameters
Knob (4) to the desired value of the welding current. Recommended parameters of the welding current to the electrode the most frequently
used species of the following table:
