Small welded machines use high -temperature arcs generated by positive and negative bipoles in the instantaneous short circuit to melt the welds and welded materials on the welded sticks to combine the contacts.Its structure is very simple, which is a high -power transformer.

Method 1: Choose a cross -shaped silicon steel chip iron core column with an cross -section area of ??about 40cm2. The winding is around the two columns of the oral iron core, and the primary coil is bronze line with φ2mm gauze, and 330 turns around one column.(Connect 220V AC electrical), the secondary 2mm × 6mm flat copper wire (commonly known as copper row) can be carried out of 102 turns, which is available for welding.Add the insulation layer), the other half is around the other column.The layer of the copper wire should be separated from a certain space between the insulation sheet to facilitate the heat dissipation. If necessary, the fan can be added according to the fan specification (voltage, interchange dynamic, etc.).Method 2: Select the oral glyph silicon steel chip iron core column with an cross -sectional area of ??about 40cm2. The winding is around the two columns of the oral iron core. The primary coil is a bronze line of φ2mm gauze, and 330 turns around one column.(Connect 220V AC electrical), use 2mm × 6mm flat copper wire (commonly known as copper row) on the secondary level to add 40 turns around the insulation layer on the primary coil, and turn to another column around the 35 turn tap as the "weak" gear.The air load voltage is 50V, and then the 15 -turning tap is the "middle" file, the air load voltage is 60V, and then the 15 turning tap is the "strong" file. The air load voltage is 70V.The layer of the copper wire should be separated from a certain space between the insulation sheet to facilitate the heat dissipation. If necessary, the fan can be added according to the fan specification (voltage, interchange dynamic, etc.).
