INSTALLATION OF MACHINE IN TIG
TIG DC WELDING (CARBON STEEL – STAINLESS STEEL – COPPER)
Connect the mains power cable to a 230V single phase line, making sure that the socket is earthed.
Place the gas bottle in a safe place and make sure that it is well secured.
Connect the TIG torch gas hose to the pressure gauge following the manufacturer’s instructions which are
included with the gauge. Pure ARGON gas recommended 4-8 lt./min. (1-2 gallon/min).
Ref. 4 Power knob with potentiometer for welding current output.
Ref. 5 Positive connector (+)for the earth cable.
Ref. 6 Negative connector (-) for the TIG torch power cable.
Open the gas valve on the TIG torch handle and ignite the welding arc by placing the electrode tip on the piece
to be welded, then lift it slowly to a distance of 3-4 mm. (0.16 in.); arc extinguishing by completion of welding is
done by electrode removal from the welding piece; let the gas outflow for a few seconds (6-8 seconds) to avoid
electrode oxidation and help electrode cooling, then close the gas valve.
