Tig Welding. Installation And Start-Up - GALAGAR SMART 200 MP Manuel Technique D'instructions

3.3. TIG WELDING. INSTALLATION AND START-UP AND
3.3.1 TIG SYSTEM INSTALLATION. TORCH TO NEGATIVE POLE.
3.3.2 TIG SYSTEM START-UP.
1) Make sure the mains voltage is 230 V.
2) Connect supply cable with the suitable plug to the relevant single-phase tap. See section 2.2.
3) Verify that the torch polarity is negative.
4) Check that the gas is Argon. If it has a mobile workstation, check that the gas bottle is securely held by the bottle-
holder system. Above all check that the safety chain is perfectly fastened.
5) Install the pressure-reducing valve and connect gas hose checking that there are no leakages, throughout the
whole circuit.
3.4. COATED ELECTRODE WELDING (MMA). INSTALLATION AND START-UP
3.4.1 MMA INSTALLATION SYSTEM. ELECTRODE-HOLDER CLAMP TO POSITIVE (REVERSE POLARITY).
3.4.2 MMA SYSTEM START-UP.
1) Make sure the mains voltage is 230 V.
2) Connect supply cable with the suitable plug to the relevant single-phase tap.
3) Connect electrode-holder clamp to polarity recommended by electrode manufacturer. Normally to positive
pole.
4) Connect earth clamp to welding table or piece to be welded. Check correct connection of welding masses.
5) Verify that electrodes are dry. If necessary, preheat electrodes for at least one hour with oven.
