Stepless Pulsed Current

Exactly, the pulse current works in short, powerful bursts. This heats the weld pool quickly and cools it between pulses – giving you good control over heat input and preventing overheating. If you don't set the pulse power cleanly, the pool will be either too fluid or you won't get proper penetration, leading to cracks or porosity. Start with a basic setting and adjust the pulse power by feel on the workpiece until the pool runs calm and even.
