TIG HF DC welding with TACK function
active and single ColdTack point
Innovative TIG HF DC tack weld device that makes it possible to
do precise, safe tack welding with very little heat applied. Thanks to
the “Perfect-Point” mode, ColdTack guarantees perfect centring of
the welding point. The “Perfect-Point” mode is activated by touch-
ing the workpiece to be welded with the tungsten tip, at the exact
point at which you wish to do the tack weld. Proceed as follows:
1) Start the welding machine by turning the power supply switch
to position I .
2) Push the SELECT WELDING PROCESS (T5) key and select
the TIG DC process, with HF ignition.
3) Press the WELDING MODE SELECTION Key (T9)
and go to one of the SPOT WELDING coldTack
function. The TACK WELD and LEDs are lit
continuously.
4) Press and release the WELDING PARAMETERS
SELECTION Key (T10) until the SPOT WELD LED
starts flashing.
5) Rotate the ENCODER knob (E) to set the SPOT
WELDING time required (0,01÷10,0 sec).

6) By pushing the WELDING PARAMETERS SELECTION (T10)
key a number of times it is possible to set the various TIG
WELDING PARAMETERS (see the “TIG Welding” paragraph
- WELDING PARAMETERS).
7) Hold the SELECT WELDING PARAMETERS (T10) key down
to save the parameters chosen.
8) Once the all the selections/regulations indicated above
have been made, welding can begin. Ignite the arc using
“distance”ignition or by touching the workpiece to be weld-
ed with the tungsten tip. In the latter case, the “Perfect-Point”
mode is activated.
9) During the welding process the DISPLAY shows the real Amps
(A) at which the operator is actually welding.

TIG HF DC welding with TACK function
active and Multi-ColdTack function
The Multi-ColdTack function can be used for cold tacking in quick
succession, to further extend the benefits of an individual ColdTack
point. Thanks to the “Perfect-Point” mode, ColdTack guarantees
perfect centring of the welding point. The “Perfect-Point” mode is
activated by touching the workpiece to be welded with the tung-
sten tip, at the exact point at which you wish to do the tack weld.
Proceed as follows:
1) Start the welding machine by turning the power supply switch
to position I .
2) Push the SELECT WELDING PROCESS (T5) key and select
the TIG DC process, with HF ignition.
3) Press the WELDING MODE SELECTION Key
(T9) and go to one of the SPOT WELDING Multi-
coldTack function. The TACK WELD LED flashes,
whereas the LED is lit continuously.
4) Push and release the SELECT WELDING PARAM-
ETERS (T10) key to be able to set the 2 parame-
ters by rotating the ENCODER Knob (E):
• Total tack welding time “t...” for the sequence of
individual ColdTack points (0,01-10,0 sec).
• Individual ColdTack point “P...” time (0,01-1,0
sec).
