400W Jewelry Welding Machine Gold and Silver Welding Machine Pulsed Laser 50A
Description：
Spark welder can be used for welding:
-Precious metal alloys; gold, silver, platinum and palladium
-Aluminum, tin and most brass alloys have certain limitations
-Alloys with different properties are not compatible in normal welding
-Alloys that oxidize during welding and therefore require an inert (argon) atmosphere
Spark welding machine for jewelry:
-Precise positioning of parts by spot welding machine
-Weld necklaces with a diameter of 0.3mm or diameter (a necklace with a smaller diameter may melt)
-Repair metal joints or breaks without removing stones or pearls
-Repair heat-sensitive metals or metal alloys
-Repair the surface or entrance of castings of the same alloy
In an inert atmosphere, soldering can be performed without flux. The solder joints are very smooth and do not require scaling or descaling.
Installation and testing：
1. Connect the electrodes, the black wire to the black connection (ground/negative), and the red wire to the red connection (series/anode).
2. Connect argon through the argon pressure reducing valve; adjust the pressure reading to the minimum
3. The tungsten wire can be sharpened by grinding on a grinding wheel or using a Fordham flexible shaft or cutting tool and grinding wheel. Please note that you should not use a grinding wheel that used to grind iron/steel, as this will contaminate the needle and cause uneven sparks and/or welding results.
4. When installing the tungsten needle, please make sure that the distance between the needle and the welding head is about 5mm. The diameter of the needle should be 0.1mm.
Specification:
Power supply: 220V 50HZ / 110V 60HZ
Power: 400W
Welding current: 0.5~50A, continuously adjustable (transient)
Weight: about 6kg
Size: 300 * 170 * 225mm
note:
Our machine can only handle small items with a diameter less than or equal to 1.2 mm, such as necklaces. No more than 1.2 mm.
Can be used with gold, silver, copper, steel, iron and other metals (except aluminum).
Using Steps:
1. Plug the device into a power outlet and then turn it on
1. Plug the device into a power outlet and then turn it on
2. Adjust the input current to start by adjusting the current adjustment dial to 1-1.5. The current adjustment dial range is 1-8. You can make necessary adjustments to the dial according to the current to make the target material get the best effect.
3. Use your fingers to check whether the gas flows through the tungsten tip. Adjust the argon until you feel the flow.
4. Clamp the object to be welded with the negative ground electrode. You cannot short-circuit the machine by making the tungsten needle and the ground clamp contact the workpiece at the same time. Do not let the target workpiece directly contact the tungsten needle. For pulse welder operation, there must be an arc gap of 0.5mm. This is the best distance for welding.
5. Make sure that the arc welding eye protection device is installed. The arc emits short-wave ultraviolet radiation, which can cause eye and skin burns. Cover the bare skin (you can wear a shirt), wear gloves and use an arc welding helmet.
6. Briefly step on the foot pedal and then release it. The arc will spot weld and spot weld where you have the tungsten electrode.
