POWER WAVE ® AC/DC 1000 ® SD
WELD PROCESS ADJUSTMENTS
Depending on the weld mode, there are a number of
adjustments that can be made, including but not
limited to Current, Voltage and WFS. These
adjustments apply to either AC or DC processes, and
control the basic parameters of the weld.
AC ADJUSTMENTS
In addition to the basic weld parameters, there are a
number of unique adjustments related to the AC
waveform of the Power Wave
® AC/DC 1000 ® SD.
These adjustments enable the operator to balance the
relationship between penetration and deposition to
tailor the output for specific applications.
WAVE BALANCE
• Refers to amount of time the waveform spends in
DC+ portion of the cycle.
• Use Wave Balance to control the penetration and
deposition of a given process. See Figure B.10.
DC OFFSET
• Refers to +/- shift of the current waveform with
respect to the zero crossing.
• Use Offset to control the penetration and deposition
of a given process. See Figure B.11.
FREQUENCY
• Power Wave ® AC/DC 1000 ® SD can produce Output
Frequencies from 20 - 100Hz
• Use Frequency to help provide stability.
• Higher frequencies in multiple arc setups can help
reduce arc interaction.
• Lower frequencies will help overcome output limita-
tions due to inductance in the Weld Circuit. See
Figure B.12.
