Arc welding equipment – Part 9 : Graphical symbols for arc welding equipment

1 Scope

This Publicly Available Specification contains graphic symbols for arc welding and allied processes equipment to identify controls, indicators, connection points, functions, and to select processes.

The symbols are for use on panel, rating plate and any documentation for arc welding and allied processes equipment.

This Publicly Available Specification does not cover graphic symbols used to alert personnel of immediate or potential personal hazards in the use of the equipment.

Note 1 – For safety symbols see ISO 3864. Note 2 – For installation instructions see IEC 62081 and IEC 62079

2 Normative reference

The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of IEC and ISO maintain registers of currently valid International Standards.

IEC 60050(851) International Electrotechnical Vocabulary (IEV) – Chapter 151 : Electric welding

IEC 60417 Graphical symbols for use on equipment - Index, survey and compilation of the single sheets

IEC 60974-1 Safety requirements for arc welding equipment - Part 1: Welding power sources

ISO 7000 Graphical symbols for use on equipment – Index and synopsis

3 Terms and definitions

The definitions in IEC 60974-1 and IEC 60050(851) shall apply.

4 Use of symbols

4.1 General

Symbols shall be placed on equipment to instruct use and operation. Examples of control panel are given in Annex B.

4.2 Selection of symbols

Symbols specified in clause 5 shall be used either as a single item or in combination to fit the intended application. Examples of combinations are given in Annex A.

Draft IEC 60974-9

3

4.3 Size of symbols

For the application of these symbols it may be necessary either to reduce or to enlarge the original to a suitable size. In the case of symbols composed of several graphic elements, or when reducing to minimum height, check that clear identification is still possible and legibility is adequate. Consider available light, user distance, and possible operating conditions as factors during size selection also.

Recommended minimum symbol size is 6 mm square.

4.4 Use of color

In general, the graphic form of a symbol reproduced in black on white or white on black should be sufficient for its identification.

For the purposes of these symbols, adequate contrast between symbol and background is most important. As long as the symbol is clearly delineated and fully legible, actual color selection is not mandatory. Be aware that certain colors, such as red, orange, and yellow are designated as safety-alerting colors.

5 Symbols

This clause presents the symbols along with its reference number, function keyword or phrase, application and source.

5.1 Letter symbols

Table 1 gives a list of letters, which may be used in a symbol.
