The pictures illustrate the waveshape of current for the process. They are not drawn to scale, and are intended only for the purpose of showing how the variables effect the waveform.
Trim in the STT mode adjusts the tailout and background portion of the waveform. Trim values greater than 1.0 add more energy to the weld and make the weld puddle hotter; trim values less than 1.0 reduce energy to weld A nominal value of 1.0 will work for most applications.

For most programs, peak current is adjusted by wave control values. A value of +10.0 maximizes the peak current, while a wave control of
NOTE: The ranges on Wave Control and Trim are dependent on the weld programs. The values shown are typical ranges.
