Spot welding machine hand-held precision pulse spot welding machine / welding machine gold and silver jewelry processing 30A welding machine

Product introduction: Spot welder can be used for platinum, gold, gold, silver, fast welding, ring, melon button, precision wire soldering, direct soldering without solder powder. Using the principle of plasma high-frequency discharge, a molten pool is formed instantaneously in the metal welding joint Adjust the output power according to the different sizes of the wires The welded workpiece is smooth, firm, fast, and efficient. Technical Parameters: Power: 220V 50/60HZ Power: 380W Dimensions: 300*180*140MM Installation and commissioning: 1. The electrode is connected to the output negative electrode, and the electrode holder is connected to the output positive electrode. 2. The tungsten needle can be sharpened on the grinder and operated by the principle of tip discharge. 3 tungsten needle installation to extend the welding head 50mm. tungsten needle diameter 1mm installation steps 1. Turn on the power and turn on the power switch. 2. Adjust the power knob, which is divided into coarse adjustment and fine adjustment. The scale value can be adjusted arbitrarily according to the work requirements. 3. Hold the workpiece with tweezers. The workpiece interface is aligned with the tungsten needle (the optimal distance is 5mm). The workpiece cannot be touched. 4. Use your foot to step on the foot switch. (Remove your foot). Spot welding is complete. Precautions: 1. The foot can't step on the foot switch for a long time. If you step on it, the machine will be short-circuited and the internal circuit will be burned out. 2. Please use this machine for precision. 3. The flash is harmful to the eyes. Please take protective measures when using it. 4.When stepping on the foot switch, do not touch the metal parts of the tungsten needle and the tweezers at the same time, otherwise there will be a needle sensation. 5.non-professionals please do not dismantle, there is high pressure.
