Welding parame-
ters in AC setup
2nd "Minimum" and "maximum" are used for setting ranges that differ according to power
source, wire-feed unit, welding program, etc.
Pos half-wave
positive half-wave
Unit -
Setting range Tri / Sin / Rec / Off
Factory setting Sin
Tri Triangular waveform
Sin Sine ... sinusoidal waveform (standard setting for a low-noise,
stable arc)
Rec Rectangular waveform with decreased edge steepness, for re-
ducing noise levels compared to those that occur with the 100%
rectangular waveform
Off 100% rectangular waveform (stable but loud arc)
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 re-
ducing 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.
