5. Set the DC offset (sine wave or
square wave weld modes only).
DC Offset (Variable Amplitude) - Control Penetration
Wave amplitude and the duration of positive and
negative cycles are independently adjustable, so the
operator can obtain deep/shallow penetration and
higher/lower deposition rates depending
on the application.
