3) Using button (3) select the welding with coated electrodes - the indicator
should indicate the operation mode marked with MMA. At the same time a
light indicating currently selected parameter - welding current Is - turns on.
With the knob (2) Fig. 1 set the appropriate welding current.
4) Pressing button (4) select the operating mode with automatic open circuit
voltage reduction (the LED indicating welding current Is illuminates
continuously) or without automatic open circuit voltage reduction (the LED
begins to blink).
5) Fit an electrode in the electrode holder.
6) After the welding is completed, the rectifier should be left connected to the
mains for some time (approx. 3 minutes). This is recommended for cooling
down the heated components.
7) If during welding, the rectifier has been overloaded by exceeding the
permitted duty cycle of 60% at currents given in Table 1, the temperature
limiter can operate. This cuts-off the welding current and lights up the
indicator (5) (Fig. 1). In such case wait until this indicator turns off, and
then you can continue the welding.
8) 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).
TIG WELDING
1) Connect the welding cable with the electric clamp (connected to the (+)
terminal) to the work to be welded.
2) Fit an appropriate tungsten electrode in the TIG welding torch (connected
to the (-) terminal).
3) Set the power switch in the position ON (ZAŁ).
4) Using button (3) (Fig. 1) select one of the three modes of TIG welding.
5) Depending on the requirements set the appropriate values of parameters.
Selection of the parameter is done by pressing P button (4), currently
selected parameter is highlighted with a red light, and the value of the
parameter is adjusted using the knob (2).
6) Set the proper gas flow using a pressure regulator on the gas cylinder.
7) Select the method of arc ignition using button (7).
