Arc Voltage Control Wire Speed Control
This control sets the arc welding voltage. It is proportional to the amount of heat in the arc. Position 6 is the highest arc voltage or heat setting.
wire Feed
This sets the wire feed speed (WFS) of the electrode wire through the MIG gun. Position 0 is 80 IPM Position 10 is 700 IPM
