Rating Information
Selection of electrode
There is no hard and fast rule by which a particular gauge of
electrode is selected. Usually this is determined by, the type of weld
required and the thickness of the workpiece. E.g. a butt weld in
1.5mm sheet metal can be done by a 1.6mm or 2.5mm electrode,
quicker. The table below gives guidance as to which electrode is
most suitable according to the welding current. This table is only a
guide, and values given are an indication only.
