Usage reference:
1:700W microwave oven transformer, choose one and a half meters, wrapped around four times can be.
2:800W microwave oven transformer, with one and a half meters, you can go around four laps, three meters on the use of folded shares, you can wind three laps. After a single quadruple winding, the secondary voltage measurement looks like 3.5V, double strands are used together (for convenience of winding, the wire can be flattened and then the tube can be insulated). The voltage in three turns is 2.9V. Look like. Dual-use, welding is better than single-use.
?
3:900W pure copper transformer, it is recommended to take two meters, the secondary winding 5 laps, with the home of double pulse (D02 or D03 version) control board, the maximum can be welded good 0.2+0.2 nickel it, the effect is very gratifying. Of course, it's okay to use a single-pulse control board to shoot one-and-a-half-half four turns. It can be welded to 0.15 nickel, and 0.2-plated nickel is basically not soldered. However, the owner can not guarantee that everyone can achieve the effect of the welder, after all, are DIY, parents must also have the psychological preparation for failure.
When you use it, you need to remove the skin, and then make the insulation on the outside (the owner of the electrical tape first wrapped and shrink heat shrink tube) for winding. Wrap around regardless of direction, just wrap around in one direction.
Matching heat shrinkable tube single choice of internal diameter of 10 or 12. Double root choose 12 or 14 inside diameter.
