The welding power source has two power terminals, one plus and one minus pole, for the
connection of the welding and the return cable. Connect the welding cable to the pole indi-
cated on the package of the electrode to be used.
Connect the return cable to the other terminal. Fit the earth clamp of the return cable to
the work-piece and make sure there is good contact between the work-piece and the
return cable terminal on the welding power source.

• Make sure that the mains cable is properly connected.
• Make sure that the welding cable or the connectors of the TIG torch and the earth
clamp are properly connected.
• Start the welding power source by setting the mains switch to position 1.
• Select the welding process you want pressing on the process selection switch.
Electrode welding process
TIG LIFT START process
TIG HF START process.
Light on the corresponding led confirm the choise.
• Set the welding current, using the knob on the front panel of the power source and
reading the current on the display.
Follow the instructions on the electrode package for the recommended welding
current in MMA welding.
In TIG welding the current must be appropriate to the workpiece and the welding
requirements.
For reducing the final crater in the weld pool is possible to select the ramp-down
function with the selection switch on the right of the front panel and to change its
value with the knob. After some seconds the control return to the welding current.
