Product Description


1.The machine is a combination of battery spot welding and circuit board solder, which makes your work more convenient.

2.Fixed spot-welding head and mobile spot-welding pen are combined together in one machine,so that the welding will become flexible.

3.Possess the function of 2,4,6,8 welding pulses selection, make the solder joint reliable.

4.Possess welding current rapid regulator, selecting the current will become quick and efficient.

5.The anti-static soldering station which controls the temperature accurately ,it is suited for welding any intergrated circuit or wiring.

6.The removable footswitches can satisfy the reqirement of welding position or sophisticated technology.

7.The fixed spot-welding head has pressure regulating device which makes the solder connections more reliable.

Attention: For the requirement for electric leakage switch is more than 60 A, it is not recommended to use at home.
