
Electrode Size
The size of the electrode generally depends on
the thickness of the section being welded, and
the thicker the section the larger the electrode
required. The table gives the maximum size of
electrodes that maybe used for various
thicknesses of section base on using a general
purpose type 6013 electrode.

Welding Current (Amperage)
Correct current selection for a particular job is
an important factor in arc welding.With the
current set too low, difficulty is experienced in
striking and maintaining astable arc. The
electrode tends to stick to the work,
penetration is poor and beads with a distinct
rounded profile will be deposited.Too high
current is accompanied by overheating of the
electrode resulting undercut and burning through of the base metal and producing excessive
spatter. Normal current for a particular job may be considered as the maximum, which can be
used without burning through the work, over-heating the electrode or producing a rough spattered
surface.The table shows current ranges generally recommended for a general purpose type 6013
electrode.

Arc Length
To strike the arc, the electrode should be gently scraped on the work until the arc is established.
There is a simple rule for the proper arc length; it should be the shortest arc that gives a good
surface to the weld. An arc too long reduces penetration, produces spatter and gives a rough
surface finish to the weld. An excessively short arc will cause sticking of the electrode and result
in poor quality welds. General rule of thumb for down hand welding is to have an arc length no
greater than the diameter of the core wire.
