- reduces the likelihood of electrode sticking (however, this is not the "Anti-stick" function);
- manual setting: allows you to set the level of the function to the minimum value, which is
insignificant, but reduces energy consumption, as well as the concentration of heat input
when welding thin metals. This reduces the likelihood of burning through, however, also
reduces the stability of short-arc burning (the unit becomes similar to a transformer
source). You can also increase the function to the maximum value for even greater short-
arc stability, but this requires a better power supply mains and increases the probability of
burning the workpiece.
What helps to achieve this: if the arc voltage is reduced below the minimum allowed
for stable arcing, the welding current increases by the default level (+40%).
In the advanced settings, you can change both the force of the "Arc-Force" [Ar.F]
and the trigger level of the function [u.AF]. Unless required, do not increase the power and
level of trigger of the "Arc-Force", because this affects the operation of the "Anti-stick"
function at large limit values, especially when welding with thin electrodes (less than Ø3.2
mm).
See paragraph 6.1 to change the value of any function in the current welding mode
3.4 “ANTI - STICK” FUNCTION
During the initial arc striking, the electrode may stick (tack to the workpiece). This
is prevented by many functions in the unit, but this can still happen, which in turn leads first
to incandescence, and then to damage to the electrode. In such a case, the unit’s "Anti -stick"
function is activated, which is built-in and operates in the MMA mode constantly, which
reduces the welding current in 0.6...0.8 seconds after this condition is detected. Also, this
makes it easier for the welder to separate (detach) the electrode from the workpiece without
