NEW Jewelry welding machine Spot Welder 400W 50A Gold Silver Platinum Palladium
Power: AC220V/110V Power: 400W Standard accessories: power cord, foot switch, workpiece clamp, tungsten needle holder, tungsten needle. All precious metal, precious metal all gold materials, such as gold, silver, Platinum, palladium. Before using the welder, check that the power supply meets the operating voltage.
Connect the corresponding output polarity of the welder output wiring (tighten the nut when the output wire is connected to the output pole). When working, clamp the workpiece with the clip on the output black line, close to the tungsten needle, depending on the size and shape of the workpiece, generally tungsten needle and The distance between the workpieces is between 0.5 and 1 mm. After the welding position is fixed, the foot switch is jogged and a high temperature arc is generated between the workpiece and the tungsten needle. The workpiece is welded in an instant. The discharge end of the tungsten needle is used before and The process must be kept sharp so that it stays well Electrical state.
Welding can change the output pulse current according to the size of the workpiece, the size of the solder joints, and the process requirements to achieve the desired effect (the machine can weld 0.5-2.5MM). When the potentiometer is rotated clockwise (coarse adjustment, fine adjustment), the output pulse current increases, and the output pulse current decreases. If the place where the welder is placed is wet or not used for a long time, it will be damp. If it is found that the above phenomenon should be dried after use, the machine should be well grounded. Please pay attention to safety when using.
