JJDH-S thermocouple spot welder is an energy storage welding machine with built-in DC battery and can be used after charging. It is specially used for on-site heat treatment, and the thermocouple wire is directly welded to the workpiece, which is small in size, light in weight, and easy to carry. Applicable to pipeline and spherical tank heat treatment site. It can be used when welding thermocouples in heat treatment sites such as shipbuilding, power station installation, and boiler manufacturing.
JJDH charges the capacitor from the internal DC battery, and uses the adjustment knob to select the welding voltage. The charging is indicated by the red light. When the voltage reaches the set value, it goes out. The green light is the discharge indicator. When the light is on, it automatically discharges about 3 seconds. Clear status indications facilitate worker operations.
