Wire feed speed to Amps

[Cracker]

Hi My 140 Amp gasless flux core welder doesn't have a wire feed speed dial just Amps and Volts. Every chart I can find on the internet for welding different thickness of metal use wire feed speed. So how can I convert WFS to Amps or does anyone know where to find a chart.
Thanks in advance.

1 amp per thou as a starting point, or 40 amps per mm and then tweak it from there depending on how the weld turns out

This may help too

Mig welders are constant voltage machines, the "amps" control is the wire speed control.
Welding current is also affected by the wire diameter and how long the stickout is.
If you really need to know precisely what wfs you're using just press the trigger for a set amount of time and measure how much comes out.
