The SoftStart function ensures a stable arc at the start of welding and was specially developed for electrodes that are welded with a low welding current (basic electrodes).
If a short circuit occurs that causes the electrode to stick during MMA welding, the power source is switched off immediately. This prevents the electrode from burning out.
To make the electrode easier to ignite, the current at the power source is increased for a fraction of a second during ignition. The HotStart function was specially developed for welding with rutile and Cel electrodes.
