•
Connect the earth cable with an electric clamp to the earth terminal (1)
Fig. 2
•
Connect the cable with electrode holder to the terminal (2) Fig. 2
Using button (6) (Fig. 1) select the polarity of an electrode cable (DC- or
DC+) in accordance with the instructions given on the electrode
packaging. For most of the electrodes being used, the welding cable with
electrode holder should be positive polarity (DC+).
6. Preparation the rectifier for TIG welding:
•
Connect the cable with an electric clamp to the earth terminal (1) Fig. 2
•
Connect the cable of TIG welding torch to the terminal (2) Fig. 2
•
Connect a gas hose from pressure regulator mounted on a shielding gas
cylinder to a gas valve connection located on the welder's rear panel.
•
Connect a gas hose connector of TIG welding torch to the quick coupler
located on the front panel of the welder (4) Fig. 2
•
Connect the control cable of a TIG torch, equipped with the appropriate
connector (C091 of Amphenol, Cat. No. T3300 001) to the socket (3)

6.2. OPERATION OF THE RECTIFIER
Prior to welding, ensure that all safety precautions and instructions specified
in section 7.1 have been observed.
6.2.1. MMA WELDING (WITH COATED ELECTRODES)
1) Connect the welding cable with the electric clamp to the work to be
welded.
2) Turn on the power switch at position ON (ZAŁ). After a while there should
illuminate the indicator (7) (Fig. 1), the digital display and the lights
indicating the last selected operation mode. The cooling fan should turn
on immediately.
3) Using button (5) select the welding with coated electrodes - the indicator
should indicate the operation mode marked with MMA. With the knob (2)
Fig. 1 set the appropriate welding current.
4) Pressing button (3) select the operating mode with automatic open circuit
voltage reduction (the LED indicating welding current Is illuminates
