• Versatile 5-in-1 Welding Mastery: Seamlessly switch between gold, cobalt-chromium alloy, mixed metal, pure titanium, and orthodontic welding modes. Handles material thicknesses from 0.8–3.5mm for jewelry repair, dental work, and hardware projects. Automatic material detection adjusts current/voltage instantly – no manual calibration needed. Perfect for intricate DIY or professional applications
• Intelligent Safety & Stability: Advanced safeguards: Auto-switch to Ortho mode after 5-minute inactivity, overload/over-temperature protection, and 40V low welding voltage. IP21-rated housing blocks liquid/debris intrusion. Non-slip feet prevent workspace scratches. 3.94ft power cord maintains safe distance from outlets during operation
• Surgical Precision Control: CNC digital technology delivers 3ms–30ms pulse accuracy and 50A–600A adjustable current. Real-time displays show welding power/duration. Programmable presets ensure consistent results for delicate tasks like jewelry links or orthodontic wire fixes. Near-silent operation (<1Hz frequency) enables focused detail work
• Pro-Grade Portability: Compact 6.1”x11.02” footprint (16.03 lbs) fits home workshops or mobile repair kits. Complete kit includes manometer, argon adapters (max 5L/min), tweezers, and grinding tools. Tool-free assembly with clearly labeled components
• Effortless Operation: Beginner-friendly with illuminated mode buttons and detailed English manual. Automatic voltage compensation maintains stable arcs. Ergonomic handle with protective socket reduces fatigue during extended sessions. Supports argon gas workflows (0.1Mpa pressure) for oxidation-free joins on titanium/gold
