Features: 1. Intelligent digital display spot welding machine, which is firm in welding and does not explode the pipe, requires 10-15V power supply by the user, and the welding current is about 100-300A. For common 0.1-0.15mm nickel plate welding 2. MoS pipe * 5, the current of spot welding can reach 2600A 3. 100 gear adjustment, digital tube real-time gear display, a total of 100 gear power, 9 gear delay can be adjusted according to the welding effect 4. Bilateral outgoing line is convenient for spot welding, and the product is marked to avoid wrong connection 5. 35cm ultra long welding pen allows spot welding to be done as you like. 2mm welding needle, extremely low resistance, no fear of high temperature, and more beautiful welding. Cold pressing process is used to contact areas of pure copper joints to reduce internal resistance Specifications: Product name: 100 gear spot welding machine Working current: 100-300A Service voltage: 10-15V Working current: Less than 20ma Standby power consumption: Less than 0.5ma Recommended use temperature: -10-60 Voltage: 12V Product size: about 8 x 4.4cm/3.15x1.73inch Multifunctional adjustment: A gear adjustment, B current display, C pulse number, D pulse delay E limit current F voltage display G save number This is a fine spot welding machine with 100-speed adjustable power, which is easy to adjust according to the welding effect. 10-15V wide input voltage design, 100-300a suitable working current, support welding 0.1-0.15mm nickel sheet.
