All technical contents of this standard are mandatory. Foreword
This standard is formulated on the basis of the industry standard [B26132000-Small Arc Welding Transformer]. GI19213—2003
Compared with 3632000, this standard absorbs the requirements of electrical energy suppliers. This requirement is not a special issue that designers pay attention to when designing welding machines, and cannot be used as a test port. In addition, the current adjustment method and the size regulations of the brand are cancelled. The appendix to this standard is the standard appendix.
This standard was proposed by the China Securities Association. This standard was issued by the National Electric Welding Machine Standardization Technical Committee. The originating units of this standard are: Panasonic Industrial Machinery Co., Ltd., Shanghai Xingxiang Electromechanical Co., Ltd. Yuying Branch 1 Zhejiang Xinghuo Machinery Co., Ltd. 2 Provincial Kende Welding Equipment Co., Ltd., Jiersi Electric Welding Machine Co., Ltd.: Technical Standard Drafting Person: Wei Zhanlin, Que Xifa, Zhu Yihui, Gongshi System. In the first national standard, B34-2330 was released: at the same time. Scope
Safety requirements for small welding transformers
GK 19213—2UC3
This standard specifies the safety requirements for the structure of small arc transformers that can be connected in reverse and the related test methods and inspections.
This standard uses small arc transformers (with simple light power supply) for welding parts under working conditions.bZxz.net
For some special requirements such as: small load duration, the user and the manufacturer can negotiate on the basis of this standard and stipulate in the relevant technical conditions:
