Offset
Using this function, the zero level is raised or lowered.
With a raised zero level, the workpiece becomes hotter and achieves better penetration.
With a lowered zero level, the electrode becomes hotter and the workpiece achieves poorer
penetration.
Offset is set in the weld data setting menu.
Only applies to TIG welding with AC.
