3.10.4 Waveform control with DC wave pulsed welding
DC wave pulsed welding is essentially pulsed welding, where a wave frequency period consists of
a low pulse section and high pulse section. The number of pulses in a low pulse section and high
pulse section in each period depends on the wave frequency and pulse conditions.
Waveform control (arc start - welding underway - crater treatment) is conducted as follows.

One period
High pulse Low pulse
