Release the torch start button.
♦ The arc is immediately shut off and the wire feed stopped, while gas flow stops
after the post-gas stage (the post-gas time is activated only if the power source has
delivered current).

3.4.3 - TIG operation.

DURING THE FOLLOWING TESTS DO NOT AIM THE TORCH AT PEOPLE OR PARTS
OF THE BODY, BUT ONLY TOWARDS AN OPEN SPACE OR THE WORKPIECE.
Shut off the power source using the switch (BU).
Connect the gas supply to the fitting (BE) on the rear panel.
Connect the power cable provided to the connectors (BF) on the wire feeder and (BO) on the
power source.
Connect the TIG torch to the central adapter (BA) of the wire feeder (also connect the patch
connector of the torch to the connector (BB) of the wire feeder, if present).
On a water-cooled torch, connect the torch cooling lines to the fittings (BI) on the wire feeder.
On a water-cooled torch, remove the temporary by-pass for coolant circulation from the
fittings (BQ), and connect the hoses provided to the fittings (BT) on the cooling unit and (BH)
on the wire feeder, matching the hose color.

Use the knob (N) to set the current based on the type of welding to be carried out.
Move the torch near the workpiece and press the torch trigger.
♦ Begin welding. Turn the knob (N) to optimize the current level.
♦ Display (O) shows the welding current (led (D) lit) and display (P) shows the arc
