New DX-50A Jewelry laser welding machine mini Spot Welder Gold Silver 400W 220V Jewelry Laser Pulse Welding Machine 

 If you need the 110V, pls contact us  

Note: 
1.Our machine can only work with small things like necklaces with a diameter including or less than 1.2mm . no more than 1.2mm
2.Can work with metal like Gold, silver, copper, steel , iron exclude aluminum.
 

Application:
1.Precious metal alloys; gold, silver, platinum and palladium
2.Titanium and stainless steel.
3.With some limitations, aluminum, tin and most brass alloys
4.Alloys with different attributes that are incompatible in normal welding
5.Alloys that would oxidize during welding and thus require an inert(Argon) atmosphere
Sparkle welder which use for jeweler:
6.Precisely position parts by tacking with the spot welder
7.Welding of necklaces with a diameter 0.3mm or larger(smaller diameter may melt)
8.Repair metal joints or breaks without removing set stones or pearls
9.Repair heat sensitive metals or metal alloys
10.Repair surface or entry point of a molding of the same alloy

With the inert argon atmosphere, welding can be done without requiring fluxing. The soldering point is smooth and does not require scaling or scale removal.


Installation and commissioning:
1.Connecting electrode, black wire to black connection (ground/cathode), red wire to red connection (positive /anode).
2. Connect argon gas through the argon gas pressure reducing valve; adjust the gas pressure reading to the minimum
3. Tungsten needle can be sharpened by grinding on the grinding wheel, or with the use of a Fordham flex shaft or dremal tool and an abrasive disk. Note that you should not use a wheel previously used to grind iron/steel as this will contaminate the needle and cause an uneven spark and/or weld results.
4. When installing the tungsten needle, please insure that the needle is approximately 5mm out from the welding head. The diameter of needle should be 0.1mm.


Steps:
1. Plug the device into the wall socket and turn it on
2. Adjust input current by adjusting the current regulating dial to 1-1.5 to start. The current regulating dial ranges from 1-8. The dial can be adjusted as necessary depending upon the current flow that gives best results for your target material.
3. Check that gas is flowing over the tungsten tip with your finger. Adjust Argon gas until you can just feel the flow.
4. Clamp the object to be welded with
