3.5 CURRENT-VOLTAGE CHARACTERISTIC SLOPE CONTROL FUNCTION

This function is primarily intended for convenient welding with electrodes with different
types of coatings. By default, the slope of the current-voltage characteristic [CVS] is set to
1.4 V/A, which corresponds to the most commonly used rutile coated electrodes (E6013).
This is not mandatory for more comfortable operation with electrodes with the main
coating type (E7015), but we recommend setting the [CVS] slope to 1.0 V/A. On the other
hand, electrodes with a cellulose coating (E6011) even require the [CVS] slope to be set to
0.2...0.6 V/A, and it is sometimes necessary to raise the "Arc-Force" [u.AF] function level to
18V.
To change the value of any function in the current welding mode, see section 6.1.

3.6 SHORT ARC WELDING FUNCTION

This function is especially useful when welding ceiling seams, when it is necessary not to
stretch the welding arc too much. For this purpose, the machine has an option to turn the
"Short-Arc" function to the "ON" position. By default, it is in the "OFF" position.
To change the value of any function in the current welding mode, see section 6.1.
3.7 NO-LOAD VOLTAGE REDUCTION FUNCTION
When welding in tanks, cisterns and places requiring an increased electrical safety system,
the no-load voltage reduction function can be activated.
When the electrode is detached from the piece, after 0.1 second the voltage at the source
terminals is reduced to a safe level below 12V.
This requires the no-load voltage reduction unit, which is present in this model of
equipment, but is in the "OFF" position by default, i.e. turned off, since it is known that
turning on any such function somewhat impairs arc ignition.

3.8 PULSED CURRENT WELDING FUNCTION

In the pulse current function of SMAW (Shielded Metal Arc Welding), there's a modulation
between a higher peak current and a lower base current. This rhythmic process aims to find
the perfect balance between metal deposition speed, heat input, and penetration depth.
During the peak current phase, enough energy is supplied for the right fusion and
penetration, while the base current phase stabilizes the arc and lessens total heat input.
This regulated pulsing can result in a more uniform and precise weld bead, minimizing
excessive heat accumulation and potential deformations of the piece.
For welders, this pulsing in MMA allows for enhanced control, especially beneficial when
dealing with heat-sensitive materials or when precise heat application is crucial. Properly
adjusting the pulse parameters, like pulse frequency and the balance between peak and
base current, can enhance weld quality, decrease spatter, and produce a desired bead
appearance.
