Note: Pulsed welding provides spray-like transfer at lower average heat input. ODPP (one-drop-per-pulse) is the target mode for best stability and spatter control.
Reference
Pulsed Welding Parameters:
Duty Cycle = (I_avg - I_bg) / (I_peak - I_bg)
I_avg = I_peak x DC + I_bg x (1 - DC)
One-Drop-Per-Pulse (ODPP) mode: frequency matched to wire feed
Typical pulse freq: 100-500 Hz for GMAW
