- manual setting: allows you to set the function level to the minimum value, which greatly
reduces power consumption at the initial moment of striking. This allows the source to
start at mains voltage values close to the minimum possible ones, but reduces the quality
of the moment of striking (the unit becomes similar to a transformer source, but it is the
only possible way in certain situations). You can also increase the function to the
maximum value to further improve the striking timing (when using good mains).
However, do not forget that the increased current of this function can burn through the
workpiece when welding thin metals, so we recommend reducing the "Hot start" in this
case.
What helps to achieve this: for a short time at the moment of arc striking, the welding
current increases by the default level of +40%.
Example: welding with Ø3mm electrode, the set main value of the welding current is
90A.
Result: The hot start current will be 90A + 40% = 126A.
In the advanced settings, you can change both the
“ Hot Start ” power [H.St], and the
“ Hot Start ” time [t.HS]. If necessary, do not increase the power and trigger time of the “ Hot
Start ” too much, because it requires a very strong power supply mains at high limit values,
and in the absence of good mains, the striking process will fail. See paragraph 6.1 to change
the value of any function in the current welding mode
3.3 “ ARC-FORCE ” FUNCTION
Advantages:
- increasing the stability of short-arc welding;
- improved drop of metal transfer into the weld pool;
- improved arc striking;
- reduces the probability of electrode sticking, but this is not the
“ Anti-stick ” function,
which will be discussed in the next paragraph;
- manual setting: allows you to set the function level to a minimum value, which slightly
reduces energy consumption, as well as the concentration of heat input when welding
thin metals, which reduces the probability of burning through, but also reduces the short-
arc stability (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 of +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
a 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
Ø 3.2 mm,
which will be discussed in the next paragraph.
