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.

3.4.2 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.
See section 2.2.
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.
