The Tooltos 50A Sparkle Argon Pulse Jewelry Spot Welder (Blue) combines plasma high-frequency discharge with optional argon gas protection — allowing oxidation-sensitive alloys to be welded without flux, producing smooth, non-blackened weld joints that require no scaling or descaling. High-quality capacitors provide strong resistance to power grid fluctuation for stable, consistent welding performance.
Key Features
Argon Gas 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. Argon gas must be purchased separately.
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.

Important Note
Argon gas is not included and must be purchased separately. The machine operates normally without argon gas, but connecting argon is recommended for oxidation-sensitive alloys to achieve cleaner weld joints.
Safety Notes
Do not hold the foot switch down continuously — step and release immediately. Prolonged contact will damage internal circuits.
Welding flash is harmful to eyes. Use appropriate eye protection during operation.
Do not disassemble the machine — high voltage is present internally.
