After learning to start and hold an arc, prac-
tice running beads of weld metal on flat
plates using a full electrode.
Hold the electrode nearly perpendicular to
the work, although tilting it ahead (in the di-
rection of travel) will be helpful.
F
To produce the best results, hold a
short arc, travel at a uniform speed,
and feed the electrode downward at a
constant rate as it melts.
