What is the purpose of a hot start?
The purpose of a hot start.
The hot start allows the controlled surge of the welding current as the arc is established a molten weld pool quickly. Without higher than the normal current, it is difficult to establish a molten metal weld pool rapidly on the metals, therefore change the length of time and percentage above the normal current.
The below Figure-(1) represents the standard method of starting welding current.
