Neg. half-wave
Negative half-wave
Unit -
Setting range Tri / Sin / Rec / Off
Factory setting OFF
Tri Triangular waveform
Sin Sine ... sinusoidal waveform (standard setting for a low-noise,
stable arc)
Rec Rectangular waveform with decreased edge steepness, for
reducing noise levels compared to those that occur with the
100% rectangular waveform
Off 100% rectangular waveform (stable but loud arc)
Phase sync.
Phase synchronisation of mains connection of two power sources for simultaneous AC
welding.
Unit -
Setting range 0 - 5
Factory setting 0
IMPORTANT! Before phase synchronisation, the "AC frequency" welding parameter
must be set to "Syn" in the AC setup.
Phase adjustment takes place as follows:
- Prepare a test workpiece for simultaneous AC welding.
- Adjust the phase synchronisation value on a power source to between 0 and 5
until the best welding result is achieved.
