(1) Increasing current increases electrode deposition
(2) Increasing current increases penetration.
(3) Excessive current produces convex weld beads with
rate.
poor appearance.
(4) Insufficient current produces large droplet transfer
and excessive spatter.
(5) Insufficient current can result in pickup of excessive
nitrogen and also porosity in the weld metal when welding
with self-shielded flux cored electrodes.
