TIG WELDING OPERATIONS

The torch is connected to the negative terminal and the earth wire to the positive. Remember to connect the gas to
the TIG torch and select the TIG mode. The only adjustable parameter is the welding current.

Nominal current
Open the shielding gas regulator to let pass the gas through the torch. Press the electrode lightly against the work-
piece (1), press the torch switch (keep it pressed until you have finished the weld) and wait for 2 seconds. The tungs-
ten electrode will heat up slightly to allow ignition of the arc (2). Slowly raise the electrode from workpiece while
rotating the torch, so that the nozzle remains in contact with the workpiece (3).The arc will start and the amperage
will increase to the pre-set level (4).
The electrode tip must be sharpened into a cone shape.In this way the arc is more stable and more energy can be con-
centrated at the weld root. Depending on the amperage used, it is recommended to sharpen the electrode to a greater
or lesser extent.
Depending on the amperage used to weld, a specific electrode diameter, nozzle and gas flow rate is recommended. Fo-
llow the reference chart below as a guide.
Amperage range (A)
10 - 60
60 - 120
120 - 170
170 - 220
220 - 350
300 - 420
If you use a torch with potentiometer control, you can vary the welding amperage setting (from the nominal value set
on the front panel to the minimum machine operating value). This allows you to reduce or increase the welding cu-
rrent setting of all parameters associated with the rated current with a single control.
