Please do not use a power strip, use a power socket to ensure a stable power supply, otherwise it may cause tripping.2. Set the pressure regulator to the correct value to avoid poor welding results.3. Please keep the surface of the soldering pin clean and wipe off the oxide layer with sandpaper.

• AUTOMATIC SPOT WELDING MODE – After switching to welding function, spot welding activates automatically without a remote foot pedal. Simply touch the two welding pen tips to the metal for 1 second, and the weld starts instantly – fast and hands‑free.
• DUAL WELDING CONFIGURATIONS (FIXED & MOVABLE) – Fixed welding head handles 0.1–0.35mm nickel‑plated strip or 0.1–0.2mm pure nickel strip. Movable welding pin supports 0.05–0.25mm nickel‑plated strip or 0.05–0.15mm pure nickel strip for greater flexibility.
• INTELLIGENT TOUCH CONTROL PANEL – Features pulse selection and start buttons with red/blue LED indicators. Red light = automatic induction mode (AT, no foot pedal). Blue light = wire‑controlled mode (MT, foot pedal connected). Easy, labor‑saving operation.
• SMART COOLING FAN – Built‑in intelligent cooling system with a fan at the rear. Activates automatically when the internal temperature reaches the rated level, ensuring stable performance and prolonging machine life.
• WIDE APPLICATIONS – Perfect for welding lead‑nickel sheets, wire meshes, lithium‑ion batteries (including 18650 packs), circuit boards, mobile phone cameras, stainless steel parts, stainless steel meshes, button cells, and battery packs of different sizes.
