Инструкция как сделать споттер, мощную точечную сварку из нескольких трансформаторов микроволновки

How to make a powerful welder from two or three microwave oven transformers: how many turns to wind, how to make electrodes, and how to choose wires. What you'll need to assemble the welder and where to get them: 👉 Microwave oven transformers or similar ones; the larger and more powerful, the better. Can be found at flea markets online or in appliance repair shops. 👉 Copper wire cable with a cross-section of 35-70 square meters. It's called PV3, PuGV, or KG 1x50. KG has rubber insulation and is more flexible. You can look for welding cable; it also has good flexibility. Audio cable is also an option, but only copper, not copper-plated aluminum. If you strip the insulation, it's better to use a cable with plastic insulation and buy heat shrink tubing for it. 👉 NML or NM wire lugs suitable for the wire cross-section. NML are tinned (L) and solder better. 👉 If welding 18650 or similar batteries, use PV1 wire (rigid, single-strand) 1*16 or 1*10 for the electrodes. Or just copper wire with a diameter of 4-6 mm. 👉 Welding timer, 100A version for 2 or more transformers http://alii.pub/6dxnjq 👉 Pedal or button http://alii.pub/6dxndb 👉 Welding electrode holder https://alii.pub/6xcxkg 👉 Nickel-plated tape for welding 18650 batteries http://alii.pub/6dxmlw 👉 220V wire with a plug, 1.5 mm square cross-section or better 2.5 mm square. 👉 Hammer, hacksaw, screws, and a real shove.
