MMA functions explanation
Arc force
The arc force function determines how the current changes in response to variations in arc length
during welding. Use a low value of arc force to get a calm arc with little spatter and use a high value to
get a hot and digging arc.
Arc force only applies to MMA welding.
START PULSE
The start pulse (similar to hot start) function temporarily increases the current in the beginning of the
weld, thus reducing the risk of lack of fusion in the starting point.
