1, No need of current-limiting resistor reduces heat resource.

2, No black spot n welding point,free of polish.

3, A built-in voltage regulator ensures constant output voltage. The welding consistency is good.

4, Full digital control with high precision.

5, Components and parts from world famous factories ensure quality.

6, The welder is easy to operation and free of complicate educational procedure. The welding effect is perfect.

7, Primary welding material:stainless steel, brass,copper alloy, and duralumin.

8,  Suitable for electric appliance,watch chain,jewelry,stainless tableware,and hardware manufactruers.
