Transformers for resistance welding machines represent the equipment of specific construction which enables concentration of high output within a small area at right effect.
Transformer winding and magnetic circuit are cast in the casing made of steel sheet-metal with special isolation substance. Thus they form a compact unit with connecting volts to the primary situated on one end and with outlets form the secondary with connections to water cooling system on the other.
The construction of the transformer comforts with the STN and DIN standards which enables transformer replacement at welding machines and lines repairs.
It is produced in variety or outputs for common welding machines and in modifications for multi-spot welding machines.
These transformers are used also in the resistance heating technology.
