The welder is equipped with a digital display (1), indicating the values of set
parameters, a knob to adjust parameter values(2), operating mode switch (3),
parameters switch (4), ignition mode switch (7) and light (8) indicating the
selected ignition mode, 4 red lights indicating currently selected operation
mode, 10 red lights indicating the currently adjusted parameter, green power
supply indicator (5) and yellow light of device overheating indicator (6).
There are four operation modes available to select with the button (3) (Fig. 1):
1)
welding with coated electrodes (MMA) - the red light should indicate
The welding current is adjustable in the range of 5 to 170A with a
resolution of 1A. The rectifier is provided with the ANTISTICK feature
facilitating electrode unsticking when it adheres to the works being welded
(when the electrode adheres to elements being welded longer than 1.5
seconds, the welding current is automatically switched off, so electrode
detaching is not difficult).
There are possible two operation modes:
a) with an automatic open circuit voltage reduction to the safe value of
approx. 12V. This mode is automatically set when the power is turned on
and after changing from another mode to MMA mode - it is signalled by
continuous illumination of the LED indicating welding current Is.
b) without automatic open circuit voltage reduction. Open circuit voltage is
sustained at a level of 90V. This operation mode can be selected by
