30A Spot Welding Machine Pulse Spot Welder Necklace Circle Welding Equipment. Uses high-frequency plasma discharge principle, the formation of the metal weld puddle moment. Adjust the output power of different sizes according to wire. Of the workpiece smooth, firm, fast, high efficiency.
Electrode holder connected to the output negative electrode holder connected to the positive output. Can be sharpened tungsten needles on the grinding machine, the use of point discharge principle. Tungsten needle to be extended when installing the weld head 50mm. Power on, turn on the power switch.
Adjust the power knob into coarse and fine. According to job requirements can be adjusted scale value. Workpiece interface alignment tungsten needle (best distance for 5mm) can not contact the workpiece. With the foot about a foot switch.
