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
allowed temperature, the welding current cuts-off and the indicator (8)
(Fig. 1).lights up. 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).
6.2.2. TIG WELDING WITH DIRECT CURRENT (DC-)
1) Connect the welding cable with the electric clamp (connected to the
output terminal (1) Fig. 2) to the work to be welded.
2) Fit an appropriate tungsten electrode in the TIG welding torch -
recommended electrode WC20 (grey).
3) Set the power switch in the position ON (ZAŁ).
4) Using button (5) (Fig. 1) select one of the three modes of TIG welding.
5) Pressing button (6) (Fig. 1) select DC- polarity.
6) Depending on the requirements set the appropriate values of parameters.
Selection of the parameter is done by pressing P button (3), currently
selected parameter is highlighted with a red light, and the value of the
parameter is adjusted using the knob (2).
7) Set the proper gas (argon) flow using a pressure regulator on the gas
cylinder.
8) Select the method of arc ignition using HF button (4).
CONTACT IGNITION - LAMP (9) IS OFF
The welding process is initiated by pressing (and releasing) a control
button on the grip. When the button is pressed the gas valve is opened.
After releasing the button
(while welding don't hold the button
pressed!)
you can ignite the arc by touching the workpiece and slightly
lifting an electrode
(the arc ignition occurs at the moment of lifting an
electrode).
