The Tooltos 50A Argon Arc Pulse TIG Jewelry Spot Welder combines plasma high-frequency discharge with argon gas protection — allowing oxidation-sensitive alloys to be welded without flux, producing smooth, non-blackened weld joints that require no scaling or descaling. With a maximum argon flow of 5L/min and supply pressure of ≥0.1 MPa, it delivers professional TIG-quality results for platinum, gold, silver, and copper jewelry applications.
Key Features
Argon Arc TIG Protection — Connect to argon gas for oxidation-sensitive alloys. Weld joints are smooth, not blackened, and require no flux, scaling, or descaling. Visual barometer accurately displays air pressure values.
High-Quality Capacitors — Strong resistance to power grid fluctuation, good voltage stabilization, and stable welding performance with reduced arc breakage.
Dual Coarse and Fine Adjustment — Precise output power control based on workpiece size, weld joint size, and process requirements.
Thickened Sheet Metal Shell — Spray-painted, wear-resistant, rust-proof, and corrosion-resistant construction with multiple cooling holes for extended operation.
Universal Voltage — Available in 110V and 220V for worldwide use.
