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-
holde r system. Above all check that the safety chain is pe rfectly 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 -holde r clamp to polarity recommende d by electrode manufacturer. Normally to positive
pole.
4) Connect earth clamp to welding table or piece to be welde d. Check correct connection of welding masses.
5) Verify that electrode s are dry. If necessary, preheat electrode s for at least one hour with oven.
