INSTALLATION OF MACHINE IN TIG HF
DC - DIRECT CURRENT
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 Positive connector (+)for the earth cable.
Ref. 5 Negative connector (-) for the TIG torch power cable.
Ref. 8 Connect TIG torch to its socket.
Ref. 9 Insert gas quick disconnector of TIG torch.
Ref. 3 Power knob with potentiometer for welding current output.
Ref. 7 Select 2/4 step position for TIG welding with or without HF (only DCi models; for CDI models see
page 19):

2 T HF Position - 2 step for stud and spot welding, keep the torch trigger pressed

4 T HF Position - 4 step allows working without the torch trigger pressed. Press the trigger;
once the arc is created, the trigger can be released and welding continued; to end the
operation, press and release the trigger again.

2-4 T without HF : use this ignition without HF in high risk areas where disturbances generated
by the HF can create interference (i.e. near computers or electronic equipment). Identical 2/4 T
functions with HF. Ignition without HF is done by scratching the Tungsten electrode tip on the pi
weld piece.
Ref. 12 By setting the slop down time, the current output drops gradually, avoiding the typical defects when
welding ends, such as shrinkage cavities. In the 2-step position this will be obtained by releasing the torch
trigger, while in position 4 -step the trigger must be kept pressed. (only DCi models; for CDI models see page
19).
Ref. 11 Setting the post-gas time, prevents electrode oxidation at the end of welding. Gas should flow for a
few seconds (8/10 recommended). (only DCi models; for CDI models see page 19).
