Water Flow Switch for the cooling water of Spot welder

(the copy rights belongs to ZHOU ENSI LTD, reproduce is not allowed)


Resistance spot welding (RSW) is a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current. It is a subset of electric resistance welding. Work-pieces are held together under pressure exerted by electrodes. Typically the sheets are in the 0.5 to 3 mm thickness range. The process uses two shaped copper alloy electrodes to concentrate welding current into a small "spot" and to simultaneously clamp the sheets together. 

When the welding machine is working, the cooling water cannot be interrupted. If the cooling water is interrupted, stop working immediately, or the welding machine will be burnt out. The flow switch is mainly installed in the water, gas, oil and other medium pipelines online or plug-in to monitor the water flow in the water system. When the water flow is higher or lower than a certain set point, trigger the output alarm signal to transmit to the machine, and the system can make corresponding indication action after obtaining the signal.

Adjustable Inline Flow Switches

GE-342 Adjustable Piston flow switch for liquid, Oil, or gaseous media...


The flow switch is to command the system switch according to the flow. Set the upper or lower limit for the flow switch, when the flow reaches the limit value, the flow switch will send a signal or alarm, and the system will run or stop. Generally, if the system requiring flow, it will use flow switch. According to the different system, the type of flow switch and other factors, the place of use is also different, which should be determined according to the specific situation.

It can be widely used in the field of industrial automation / mechanical equipment / air compression industry / refrigeration and air conditioning. It can also be used in the field of water-cooled welding machine, laser equipment cooling system, vacuum coating machine, electric furnace, polysilicon ingot furnace, etc. The water flow switch magnet is not in the flowing water channel, which can be used in the sewage system and can work normally.
