Set the machine so that you are at welding amperage with the foot pedal depressed about 3/4 of the way.

The 1/4 pedal that you have left is for just in case reserve, just like driving a car..

Having the amperage set this way gives a lot more control than just setting the machine to 200 amps and controlling everything with the foot pedal.

I don’t know about you but sometimes I lose focus when welding long periods.

I don’t want any chance of welding with 200 amps if all I need is 50 amps.

My ankles pop sometimes too, one ankle pop and you might jump or drop 30 amps if your machine amperage is too high.
