【Precision Welding】Pulse argon arc welding machine adopts automatic point contact welding method, which has higher precision and small welding surface. 【Various Welding Modes】The machine has 5 welding modes, 1-key switching welding mode, adjustable power and welding time,allow customization of spot weld diameter. changing welding performance parameters of welding method, very convenient. 【Protect Workpiece】Minimum workspace is required, adjustable power and pulse settings When there is no operation for 5 minutes, the unit will enter Ortho mode to avoid damage to workpieces. 【Achieving Precise Control】The working principle of the product is spot welding, when the workpiece touches the welding needle it will automatically shrink the rod. If you need to weld different diameters of workpieces, you need to adjust the welding time and welding power to achieve the best welding effect. 【Applications】The spot welder can be used for platinum, gold, K gold, silver, copper, stainless steel, cobalt, chrome alloy, titanium, hardware workpiece, jewelry restoration, dentistry, jewelry DIY production and other precious metal welding.
