Making your welder a much more useful tool. What an improvement!
This data-comparison helps us to determine what the current should be and what the frequency of the pulse, especially for welding thinner steel sheets with butt-welding.
The setting welding current is 100A, base current 5A.
In my opinion, up to 900Hz from 500Hz, the higher the frequency of the pulse the easier the control of the arc.
This comparison tells we can raise the welding current safely in higher frequency, since the actual peak welding current does not go up too big for thinner sheet.
Because of that same issue, I started adding an extra resistor to all my crystal oscillator circuits. The old design started randomly jumping to third overtone which isn't at all what was intended.
Setting means a lot to this retrofit-unit, for this MIXTIG setting better use 70% to 80% alternative current wave, and 30% to 20% dirrect current especially for thinner aluminium like above case, 1.5mm thick.
Several hits and errors made me get information of better setting.
Hope you can do it better than these above!
