burn‐through, but also reduces the stability of short arc burning (the machine
becomes similar to a transformer source). The function can also be increased to
maximum value for even better stability of short‐arc burning, but this requires for
better supply mains and increases the risk of work piece burn‐through.
The result is achieved by the following means:
Due to reduction of arc voltage below the minimum permissible voltage of stable
arc burning, arc current increases by the default value of +40%.
In the additional settings, you can change both Arc Force magnitude [Ar.F] and
trigger level of this function [u.AF]. Do not set Arc Force magnitude and a trigger
level to unnecessarily high value, because at high limit values, especially during
welding with thin electrodes less than Ø3.2mm in diameter, affects actuation of
Anti‐Stick function, which will be explained in the next clause.
See Clause 6.1 for sequence of changing the value of any function in the current
welding mode.
3.4 ANTI‐STICK FUNCTION
During the initial arc striking, the electrode can stick or be tacked to the work
piece. Many functions of the machine resist this occurrence, but it is possible
nevertheless, first leading to overheating and eventually to damage of the
electrode.
In such a case, this machine actuates the built‐in Anti‐Stick function, which is
constantly operating in the MMA mode. Within 0.6...0.8s after detection of this
condition, this function reduces welding current. In addition, this function helps the
