Types of Electrodes
Arc Welding electrodes are classified into a number of groups depending on their applications. There are a
great number of electrodes used for specialized industrial purposes, which are not of particular interest for
everyday general work. These include some low hydrogen types for high tensile steel, cellulose types for
welding large diameter pipes, etc. The range of electrodes dealt with in this publication will cover the vast
majority of applications likely to be encountered; are all easy to use and all will work on even the most basic of
welding machines.

Electrode Comments
Mild Steel 6013
Ideal electrodes for all general
purpose work. Features include
outstanding operator appeal, easy
arc starting and low spatter.
Mild Steel 7014 All positional electrode for use on
mild and galvanized steel furniture,
plates, fences, gates, pipes and
tanks etc. Especially suitable for
vertical-down welding.
Cast Iron 99% Nickel
Suitable for joining all cast irons
except white cast iron.
Stainless Steel 318L-16 High corrosion resistance. Ideal
for dairy work, etc.
Copper, Bronze,
Brass, etc. Bronze
5.7 ERCUSI-A
Easy to use electrode for marine
fittings, water taps and valves,
water trough float arms, etc. Also
for joining copper to steel and for
bronze overlays on steel shafts.
High alloy steels,
dissimilar metals,
crack resistant,
all hard-to-weld
jobs. 312-16 It will weld most problematic jobs
such as springs, shafts, broken
joints, mild steel to stainless and
alloy steel.
Not suitable for Aluminium.
