5C) BALANCING ( BALANCE
PLUS)
It is possible to adjust the time (t) and amplitude of the current (I) while the electrode stays in place
simultaneously and independently, using positive or negative values, guaranteeing perfect control of
penetration and cleanliness, drastically reducing side incisions.
For simultaneous setting of the parameters, following the instructions given in points 5A and 5B in
succession, with the help (if necessary) of the example shown below.

t -15 65% 35%
I -20 120% 80%
6) FREQUENCY CONTROL IN AC (40 - 250 Hz)
This controls the frequency for the various wave shapes, for better directional control, reducing the thermally
altered area, with greater penetration and lower electrode
consumption. The high frequency makes it
possible to weld very small thick- nesses with excellent results, while the low frequency is ideal for welding
average thicknesses, or where edge preparation is poor.
To regulate the FREQUENCY push the BALANCING and FREQUENCY key (T4) twice (FREQUENCY
LED flashing) and use the ENCODER Knob (E) to regulate the value indicated on the DISPLAY (D).
To exit, simply push the BALANCING and
FREQUENCY (T4) key again (FREQUENCY LED off).
