Feature
1. The top and bottom cover of the liquid accumulator welding machine is outfitted with a 120KJ medium voltage capacitor discharge welding unit.
2. The welding system is equipped with a gas-liquid force-cylinder pressurization system.
3. Gate-type body mechanism.
Background information
Fridge air compressors with liquid accumulators are typically constructed form components that undergo a brazing process in a furnace, which requires a large production center with high amounts of energy consumption. Now, we utilize electric resistance technology and the welding process can be finished in seconds, saving energy and time.
This product is one of the most comprehensive in the industry.
