WELD PROCESS ADJUSTMENTS	DC OFFSET

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.

•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.

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.

•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
