Welding machine operating in voltage control mode:
1. Operating system -- VR/Rx
Welding machine controlled by current:
E Operating current - VR/R
L --- Minimum rated voltage of welding machine, in V (nominal value - tolerance) Minimum rated current of welding machine, in ampere (A) (nominal value: tolerance): R.
Minimum resistance value of pipe fittings provided by the manufacturer at reference temperature, in ohm (0): Maximum range resistance value of pipe fittings provided by the manufacturer at reference temperature, in ohm (1). 1 )
At ambient temperature, after state adjustment, the resistance value of the pipe fittings and the resistance meter measured by the double-tube bridge electric accessory instrument meet the requirements of Table 13.:
When measuring resistance, the ambient temperature at the instrument should be within the accuracy of 23°C. The pipe should be connected to the specified state conditioning (for example, m or 1 product). If the pipe is removed from the state conditioning environment to measure resistance, the time shall not exceed 3: Table D.1 Working characteristics of resistance measuring instrument

Technical differences
Deleted [ISO/CI) E2093. Added ISI)12176-2:2000. The rest adopts the national standards corresponding to the international standards.
ISO/CE 12093 is no longer quoted. The regulations shall be stated by the manufacturer in the technical documents.
ISO/CE 12093 is no longer quoted in D. 1 and D. 2. Instead, the R. and Rx values ​​provided by the manufacturer are recorded. The sugar content and accuracy of the electric cathode measuring instrument in Table [. 1 in D. 1 have been modified. The resolution has been changed from 0.1mQ to 1mo, 1ma to 1mn, and mn to 1001ItS2. The accuracy has been changed from 0.25% of the reading to 2.5% of the reading.
GB/T 19807-2005
International standard ISO/CF12093 has no official text so far; ISO ()12176 2 is added for the convenience of reuse and to comply with the national standard abbreviation regulations, emphasizing the consistency with GI3/T 1. 1.
International standard ISO/CU) 12093 has not yet been officially published, and it is not easy to unify. Therefore, this standard stipulates that the manufacturer should explain it in the technical documents, which is in line with my country's national conditions and convenient for use.
The reason is the same as above.
Taking into account the operability and the actual production situation in my country.
