200W 50A Jewelry Laser Welding Machine 110V/220V Optional Mini Spot Welder MachineDescription:- Precious metal alloys; gold, silver, platinum and palladium- Titanium and stainless steel.- With some limitations, aluminum, tin and most brass alloys- Alloys with different attributes that are incompatible in normal welding- Alloys that would oxidize during welding and thus require an inert (Argon) atmosphere- Sparkle welder which use for jeweler:- Precisely position parts by tacking with the spot welder- Welding of necklaces with a diameter 0.3mm or larger (smaller diameter may melt)- Repair metal joints or breaks without removing set stones or pearls- Repair heat sensitive metals or metal alloys- 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.Specifications:- Optional Power Supply: 110V, 220V- Power: 200W- Ampere for welding: 0.5 ~ 50A, continuous adjustable (fluctuation)- Welding range: 0.5 - 1.2mm- Weight: about 5kg- Size: 300 * 220 * 150mmPackage Included:1 * Welder1 * Foot Pedal1 * Power Cord1 * Tweezers Clip1 * Tungsten Pin1 * Socket
