Air-air type cooler
The air-to-air type cooler is a simple system. It consists of a radiator to cool the liquid in the machine efficiently. The BTU load is calculated by the power of the machine in KVA, in order to obtain the required liquid capacity.
It is the cheapest type of cooler compared to other systems.
This type of cooler makes the machine independent since it has its own cooling system.
If the system is well maintained, it prevents crystallization in the welding machine.
