The Iron Moulders' Society of South Africa (IMS) was a trade union representing metalworkers in South Africa. The union was founded in 1896. [ 1 ] It was strongly focused on the rights of white workers, and sought to exclude others from working as moulders.
Within the SAT&LC, the union argued against representation for black workers, and in 1947 it resigned over the issue. The following year, it was a founding affiliate of the all-white Co-ordinating Council of South African Trade Unions, and then from 1957 part of the larger South African Confederation of Labour (SACOL). By 1976, it had 36,000 ...

Properly done, the iron heats the parts to be connected, which in turn melt the solder, guaranteeing adequate heat in the joined parts for thorough wetting. If using solder wire with an embedded flux core, heating the solder first may cause the flux to evaporate before it cleans the surfaces being soldered.

Melting the solder can release toxic fumes, particularly solder with higher proportions of lead. It is recommended to work in a well-ventilated area; to avoid inhaling the toxic fumes; and to wash hands with soap after operating with a soldering iron. It is also recommended to use lead-free solder to mitigate the risks of lead exposure. [30] [31]
