1. Control knob for welding dynamics
Dynamics function controls the rate of rise of current when the filler wire is in short circuit
with the welding plate. This control adjustment is necessary due to the alternative welding
parameters, materials, wire sizes, gas types and current values used.
The welding dynamics scale is –9 to +9. Negative values make the rise of current slower, which
results in a hotter and more fluid weld characteristic. Positive values make the rise of current
faster, which results in a colder welding condition. This can result in more spatter during
welding depending on the filler wire size and type used.
How to find the optimal dynamics setting?
Start by setting '0' and make a test weld after selecting the correct wire feed speed and
voltage values. Fine tune the welding arc by trying different values in the negative (-) and
positive (+) sides of the dynamics scale.
2. Control knob for wire feed speed
This control knob increases and reduces the speed of filler wire delivery to the welding arc.
The scale is regulated in meters per minute. There is also a graphical display bar indicating the
proportion of motor speed selected.
