-13 - PATON StandardMIG MMA/TIG/MIG/MAGburn‐through, but also reduces the stability of short arc burning (the machinebecomes similar to a transformer source). The function can also be increased tomaximum value for even better stability of short‐arc burning, but this requires forbetter 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 ofstable 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 atrigger level to unnecessarily high value, because at high limit values, especiallyduring welding with thin electrodes less than Ф3.2mm in diameter, affectsactuation 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 currentwelding mode.3.4 ANTI‐STICK FUNCTIONDuring the initial arc striking, the electrode can stick or be tacked to the workpiece. Many functions of the machine resist this occurrence, but it is possiblenevertheless, first leading to overheating and eventually to damage of theelectrode.In such a case, this machine actuates the built‐in Anti‐Stick function, which isconstantly operating in the MMA mode. Within 0.6...0.8s after detection of thiscondition, this function reduces welding current. In addition, this function helps the
