thin metals, which reduces the probability of burnout, but also reduces the stability of the
short arc (the machine becomes similar to a transformer source).
It is also possible to increase the function value to a maximum value to achieve even higher
short arc stability, but this requires a better mains supply and increases the probability of
burning through the welded workpiece.
This is achieved by
: if the arc voltage is reduced below the minimum allowable value for a
stable arc, the welding current increases by a default level of +40%.
In the advanced settings, both the "Arc-Force" [Ar.F] power and the function release level
[u.AF] can be changed. Unless required, the power and trigger level of the "Arc-Force"
function should not be increased as this affects the performance of the "Anti-stick" function
at high limits, especially when weldin
g with thin electrodes with a diameter of less than Ø3.2
mm, as will be discussed in the next section.
For the procedure for changing the value of any function in the current welding mode, see Section 6.1.
3.4 "ANTI-STICK" FUNCTION
During the initial arc strike, the electrode can stick to the workpiece; this is prevented by
many features of the device, but can still happen, resulting in damage to the electrode.
In
this case, the "Anti-Stick" function is activated, which operates continuously in MMA mode
and reduces the welding current within 0.6...0.8 seconds of detecting this condition. This also
makes it easier for the welder to separate (disconnect) the electrode from the workpiece
without the risk of burning his eyes through accidental arc starting. Once the electrode is
detached from the workpiece, the welding process can continue unhindered.
