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.
