WELD PROCESS ADJUSTMENTS
Depending on the weld mode, there are a number of
adjustments that can be made, including but not limit-
ed 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. These
adjustments enable the operator to balance the rela-
tionship 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.
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.
FREQUENCY
• POWER WAVE AC/DC 1000 can produce Output
Frequencies from 10 - 100Hz
• Use Frequency to fine tune stability
• Higher frequencies in multiple arc setups can help
reduce arc interaction
