Detailed explanation of cooling water system for precision spot welder


The heating parts of the inverter precision spot welding machine are: welding transformer, electrode arm, electrode, conductive plate, ignition tube or thyristor switch. These heat-intensive parts must be cooled by water.
When designing such components, in addition to ensuring that their own parameters meet the requirements, water cooling and cooling water passages should also be considered. Some precision spot welder welding transformers will be burned during use due to improper design of the cooling water circuit or processing technology.
The cooling water system is an indispensable part in the inverter spot welding machine. All precision spot welding machines with cooling water channels must be connected to water before they can be turned on.
From the perspective of cooling water distribution, the spot welding machine welding transformer needs a separate circuit. The upper electrode and the upper conductive plate are connected in series to form a circuit. The lower electrode and the lower conductive plate are connected to form another circuit in series. Into a loop. These branch circuits are connected to the centralized inlet and outlet pipes. When the water pipe joint is connected to the hose or steel (copper) pipe, it should be tight and reliable and must not leak. This is even more important for welding transformers and thyristor switches.
The connection between the water inlet and outlet pipes of the precision spot welding machine and each circuit is generally a hose. Its material is a cloth-clamping hose or a nylon tube reinforced with nylon filament. The commonly used pipe diameters are 10, medium 15, and 20mm, and can be smaller in the electrode part. All hose arrangements should be neat and beautiful and properly fixed on the welding machine.
