15.1 Current Setting - Tig Mode (Manual)
Turning the main display knob adjust the welding current.
NOTE: on manual tig mode the material tickness setting is not available.
15.2 Trigger Setting - Tig Mode (Manual)
Plug the tig torch to the negative polarity and the torch trigger plug to the respec-
tive socket. In case of remote control function, use the remote control socket.
Torch gas hose must be screwed to the machine gas nipple.
The welding generator can be equipped with cooling unit: in that case a water
cooled tig torch may be used plugging the water inlet/outlet hoses.
NOTE: generator provided with cooling unit can support even gas cooled tig
torches. Do not forget to close the water circuit by using a suitable by-pass
hose placed between the inlet and outlet nipples (front and rear).
Using an appropriate hose connect the gas bottle to the inlet gas nipple placed on
the rear panel (market with tig) – release the gas flow at 5/7 lt/min.
The MULTI generators provide tig torch arc strike by using the Lift-Arc method:
push the torch trigger
slow down the torch until the ceramic
nozzle touch the
workpiece; in this phase held the torch and
avoid any contact between tungsten and
workpiece
keeping the nozzle in contact, turn the
torch until the tungsten enters in contact
with the workpiece
maintaining the nozzle-work piece contact,
turn back the torch to the original posi-
tion; the arc strikes and the welding can be
performed
