The welding tools are smoothly, strong, fast and effective. Great for jewelry making and processing. Tweezers made of insulating material, smoothly hand fell, strong and durable.The power regulator can adjust the scale value arbitrarily at the upper part of coarse adjustment and fine adjustment at the bottom. Can be used for rapid welding of platinum, gold, k gold, silver, etc. Foot switch controls welding time during spot welding, convenient for operation. Condition: 100% Brand New Item Type: Spot Welding Machine Material: Metal Uses: Spot welding machine can be used for rapid welding of platinum, gold, k gold, silver, precision welding of ring mouth, buckle, thin wire, direct welding without solder powder. Power Supply Mode: The plug is connected to the power supply for use. Welding Range: 0.6-1.2MM Power: 300W Welding Current: 0.5A-50A Power Supply Mode: Directly plug in the power cord to use. 50A Soldering Machine Usage: 1. Before using the welding machine, check whether the power supply meets the operating voltage.
Connect the screws of the corresponding polarity to the output wiring of the welding machine (the nut should be tightened when the output wire is connected to the output pole). When working, use the clamp on the output black line to clamp the workpiece, close to the tungsten needle. The distance depends on the size and shape of the workpiece. Generally, the distance between the tungsten needle and the workpiece is between 0.5-1 mm.The discharge end of the tungsten needle must be keep sharping before and during use to keep it in a good discharge state. In welding, the output pulse current can be changed according to the size of the workpiece, the size of the solder joint, and the process requirements to achieve the desired effect. When the potentiometer is turned clockwise (coarse adjustment, fine adjustment), the output pulse current increases, otherwise the output pulse current decreases. The electrode is connected to the negative output and the electrode holder is connected to the positive output. The tungsten needle can be ground on a grinder and can be operated according to the principle of tip discharge. The diameter of the tungsten needle is 1.5mm. Adjust the power knob, divided into coarse adjustment and fine adjustment. The scale value can be adjusted arbitrarily according to work requirements. Clamp the workpiece with tweezers, and the workpiece interface is aligned with the tungsten pin (the distance is 5mm). The workpiece cannot be touched. Depress the foot switch with your foot and remove the foot. Do not step on the foot switch for a long time.
If you step on it, the machine will short-circuit and the internal circuit will be burned. The flash is harmful to eyes, so protective measures should be taken when using it. When stepping on the foot switch, do not touches the tungsten needle and the metal part of the tweezers at the same time, otherwise there will be a needle feel. Non-professionals do not take the disassembly method, there is high voltage.300 x 220 x 150mm / 11.8 x 8.7 x 5.9in. 1 x Spot Welding Machine.
