It is one
16、of a Series of Standards issued by the Canadian Standards Association under Part II of the Canadian Electrical Code. It supersedes previous editions published in 1951, 1959, 1983, and 1986, and is written in SI (metric) units. In this new edition, the Standard has revised the requirements for enclos
17、ure openings by introducing the IEC test finger and has clarified the output shortcircuit test requirements for different types of welders. For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface of C22.2 No. 0, General Requirements-Canadian Electrical Code
18、, Part II. This Standard was prepared by a Subcornniittee of the Technical Committee on Industrial Products under the jurisdiction of the CSA Standards Steering Committee on CE Code, Part II and was formally approved by these Committees. May 1990 Notes: (1) Use of the masculine gender in this Standa
19、rd is not meant to exclude the feminine gender when applied to persons. Similarly, use of the singular does not exclude the plural (and vice versa) when the sense allows. (2) Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains th
20、e responsibility of the user of the Standard to judge its suitability for his particular purpose. (3) CSA Standards are subject to periodic review, and suggestions for their improvement will be referred to the appropriate committee. (4) All enquiries regarding this Standard, including requests for i
21、nterpretation, should be addressed to Canadian Standards Association, Standards Division, 178 Rexdale Boulevard, Rexdale, Ontario M9W 1R3. Requests for interpretation should (a) define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sketch; (b) p
22、rovide an explanation of circumstances surrounding the actual field condition; and (c) be phrased where possible to permit a specific “yes“ or “no“ answer. Interpretations are published in CSA Information Update. For subscription details and a free sample copy, write to CSA Marketing or telephone (4

C22.2 No. 60M1990 May 1990 Page 7 Foreword Certification organizations, as accredited by the Standards Council of Canada, have their own criteria and procedures for certification services. The following paragraphs define CSA Certification policies. The Canadian Standards Association pro
24、vides certification services for manufacturers who, under license from CSA, wish to use the appropriate registered CSA Marks on certain products of their manufacture to indicate conformity with CSA Standards. CSA Certification for a number of products is provided in the interest of maintaining agree
25、dupon standards of quality, performance, interchangeability and/or safety, as appropriate. Where applicable, certification may form the basis for acceptance by inspection authorities responsible for enforcement of regulations. Where feasible, programs will be developed for additional products for wh
26、ich certification is desired by producers, consumers or other interests. In performing its functions in accordance with its objectives, CSA does not assume or undertake to discharge any responsibility of the manufacturer or any other party. The opinions and findings of the Association represent its
27、professional judgement given with due consideration to the necessary limitations of practical operation and state of the art at the time the Standard is processed. Products in substantial accord with this Standard but which exhibit a minor difference or a new feature may be deemed to meet the Standa
28、rd providing the feature or difference is found acceptable utilizing appropriate CSA Certification Division Operating Procedures. Products which comply with this Standard shall not be certified if they are found to have additional features which are inconsistent with the intent of this Standard. Pro
29、ducts shall not be certifiable if they are discovered to contravene applicable Federal laws or regulations. Testing techniques, test procedures and instrumentation frequently must be prescribed by the CSA Certification Division in addition to the technical requirements contained in Standards of CSA.
30、 In addition to markings specified in the Standard the CSA Certification and Testing Division may require special cautions, markings and instructions that are not specified by the Standard. Some tests required by CSA Standards may be inherently hazardous. The Association neither assumes nor accepts
31、any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed, whether performed in whole or in part by the manufacturer or the Association, and whether or not any equipment, facility or personnel for or in connection with the test is furnished by th
32、e manufacturer or the Association. Manufacturers should note that, in the event of the failure of the CSA Certification and Testing Division to resolve an issue arising from the interpretation of requirements, there is an appeal procedure: the complainant should submit the matter, in writing, to the
33、 Secretary of the Canadian Standards Association. If this Standard is to be used in obtaining CSA Certification please remember, when making application for certification, to request all current Amendments, Bulletins, Notices and Technical C22.2 No. 60M1990 May 1990 Page 8 Information Letters that m
34、ay be applicable and for which there may be a nominal charge.

Scope 1.1 This Standard applies to arc welding equipment for voltages up to and including 600 V, intended for use in nonhazardous locations in accordance with the Canadian Electrical Code, Part I. The following types of equipment are included
38、 in this Standard: (a) singlephase transformers or transformerrectifiers; (b) polyphasetransformers or transformerrectifiers; (c) motor or enginedriven alternators and generators; (d) associated electrical attachments such as wire drive units, arc stabilizer units, remote controls, and optional kits
39、; (e) plasma arc equipment operating in excess of 100 V dc (eg, plasma arc cutting equipment). 1.2 This Standard does not apply to: (a) resistance type welding equipment; (b) arc welders having oilinsulated transformers; (C) welding equipment used in unusual service conditions such as (I) exposure t
40、o unusually corrosive fumes; (ii) exposure to steam; (iii) exposure to abnormal vibration or shock; (iv) exposure to unusual seacoast or shipboard conditions; or (v) hazardous locations. Note: The short term “welders“ is used throughout this Standard. 1.3 Supplementary requirements that apply to pla
41、sma arc equipment are specified in Clause 7 of this Standard. 2. Definitions 2.1 The following definitions apply in this Standard: Automatic welder-a welder intended for use only with automated welding apparatus.
