If the welder is used for a long time or under excessive load, the welder will become hot and smoke, and the coil will be short-circuiting when the current is too large. The temperature control switch is installed in most current welders. When the circuit is abnormal or the temperature is too high, the temperature control switch will start to protect the welder. The temperature control of the welder is usually installed on the radiator of the power tube or on the main transformer. The protection temperature is generally selected from 90 to 120 degrees.

At present, this kind of small arc welder control transformer is in the market. The installation mode of the protector on the transformer is basically embedded, directly embedded in the coil winding. During the winding process, the thermostat is sandwiched directly between the windings. That is, the protector is placed on the inside of the skeleton, and the coil is wrapped around it. The fixed way of the temperature controller with this simple embedded type, can choose small volume HKW9700 series thermal protector.

Welding machine HKW9700 temperature control switch

HKW9700 series thermal protector is generally used in electric welders, because it can play the role of overheat protection caused by overload and abnormal conditions.

There are two kinds of PBT plastic shell and iron shell, the current effect is small, will not produce a large temperature difference due to overcurrent. This type of welder can be considered for use.
