3.2 "HOT-START" FUNCTION
The Hot-Start manual configuration provides precise modulation of the inception welding
amperage during the arc ignition phase. This facilitates equilibrium between energy
expenditure and ignition consistency.
The advantages provided by the function are as follows:
-
Highest Ignition Proficiency:
Ensures optimal arc initiation, even with low-ignition
potential electrodes.;
-
Enhanced Base Material Penetration:
Achieves deeper and more consistent
penetration at the ignition phase, thus mitigating potential workpiece damage.;
-
Inhibition of Slag Inclusions:
Actively counters the onset of slag inclusions during
the welding process.
Manual Adjustment:
This feature enables users to set the function level to its minimum
value, resulting in a significant decrease in energy consumption during the initial ignition
phase. This allows the power source to start with voltage levels close to the minimum
achievable range, although it does impact the quality of the ignition moment (making the
apparatus similar to a transformer source). Alternatively, the function can be increased to its
maximum value to enhance the ignition moment (when working with a stable power grid).
However, it's crucial to remember that using the increased current from this function can
lead to the workpiece burning through when welding thin metals. Therefore, we recommend
reducing the value of the "Hot Start" function in such situations.
Operational Illustration:
For an arc initiated with a 3mm electrode at a primary welding
current of 90A, the "Hot-Start" functionality temporarily augments the welding current by a
default of 40%. Consequently, the resultant "Hot-Start" current becomes: 90A

1.40=126 A
In the Advanced settings, you have the option to adjust both the "Hot Start" power [H.St]
and the "Hot Start" time [t.HS]. It's crucial not to increase these values excessively. When set
too high, a robust mains supply is required. If the mains supply is not sufficiently strong, the
ignition process may not succeed.
To change the value of any function in the current welding mode, see section 6.1.
3.3 "ARC-FORCE" FUNCTION
Advantages of the function:
-
excellent short-circuit arc welding stability;
-
improved transfer of metal droplets into the weld pool;
-
improved arc ignition;
-
reduces the probability of electrode sticking, but it is not an "Anti-Stick" function,
which will be discussed in the next paragraph;
Manual setting:
allows the function level to be set to a minimum value, which slightly
reduces the energy consumption and also the concentration of heat input during welding of
