AC AMPLITUDE CONTROL
Independent amplitude control is a very advanced feature and has many benefits, this allows the EN and
EP amperage to be set independently allowing the user to direct more or less power into the workpiece
and also take power / heat away from the tungsten.
Increasing EN amperage while maintaining or reducing EP amperage narrows the arc allowing narrower
welds and use of a smaller tungsten.
A good example is welding thicker aluminium, you can enter a high EN amps and a much lower EP into
the tungsten. This will provide faster travel speeds, better penetration and faster filler rod insertion.
How to setup
AC Mode
-
Manual Home screen
Use arrow buttons to highlight amplitude in red, then use control knob to switch between off/on.
Once switched on, you will see EN
-
and EP+ appear in middle of display, you can now use arrow buttons
to highlight these in red and use the control knob to adjust accordingly.
