Features: The welding process is based on the principle of high current and high temperature, rapidly melting part of the nickel sheet, and cooling, can fully meet the requirements of small spots welding machine, stable quality, solid welding and no tube frying. 5 Gears Adjustment: 5 gears of power adjustable program, the welding process is more accurate and the welding effect is more perfect. With indicator light and buzzer function. 5 MOS Tubes: Adopts 5pcs MOS tubes, support acceptable up to 1500A spots welding current, welding more firmly and more widely. High Frequency Capacitance: The use of 25V low internal resistance high-frequency capacitors to make the power supplying more stable. Support Spots Welding Battery Type: Support for welding 18650/26650/32650 and other cylindrical lithium batteries, NiMH batteries, etc., can be welded firmly. Support Nickel Sheet Type: Support for welding nickel sheet with the thickness of 0.1mm-0.15mm, and with solid and beautiful welding spots. Superior Welding Pen: Dedicated 350mm spots welding pen, soft silicone wire are consists of multiple strands of high-temperature wire with high torsional resistance and more sensitive operation. Copper Needle Design: With alumina copper spots welding needles, large contact areas with pure copper joints to reduce internal resistance, to ensure high current passing capacity and durability. Common Working Power Supplies in the Market: 12 V carstart power supplies, 3S model aircrafts battery packs, 3S high rate lithium battery packs, 12 V over 60A stable performance leadacid batteries.
