WELDING TIME AND CURRENT SETTINGS
14
This page is intended as a guide to setting your
machine.
A set of basic formulae as defined by the British
Standard BS EN ISO 14555:2006 (European
Standard EN ISO 14555:2006) Annex A.2.7.2.2
and Annex A.2.7.2.4 may be used to calculate
the current and time settings to weld any stud.
These formulae when applied to standard studs
give results shown in the table on this page. A
graphical representation of the data is also
illustrated below.
The settings generated in the table are only
intended as a starting point. It is possible that
the settings will give
satisfactory results
without adjustment, but
in reality the quality of
the welding results is
governed by many
variable factors. These
include, most
obviously, the welding
time, current and arc-
gap (pistol lift) as
covered in the table, but
can also include factors
such as stud and work-
piece material type and
condition, ambient
temperature, relative
humidity, quality of
supply etc. etc. All of
these factors can act on
the weld to change the
outcome. It is
recommended that in all
instances, you need to
carry out sample welds
in your actual
conditions and
environment. This will
enable you to alter the
settings, where
necessary, to achieve
welds that are most
acceptable to you.
