Mixed Arc

Between the arc types short and spray arc is the mixed arc which is characterized by strong
spatter formation.
Spray Arc
Spray arc transfer time view
The spray arc burns continuously without a short-circuit interruption. The material transfer
from the wire electrode into the weld pool is fine-droplet. It is relatively high thermal energy
introduced into the weld metal, which is why heat affected zone and thus the workpiece
distortion are greater than the short arc. This type of arc is used to weld thicker sheets.
