WELDING INSTEAD OF SOLDERING
Glossary of terms
Electric welding significantly reduces the time spent on assembly work, alienates connections that withstand high-temperature heating, does not require solders, fluxes, pre-tinning, allows to connect conductors from metals to alloys that are difficult to solder, for example, wires of electric heaters.
For welding it is necessary to own a spring of constant or alternating current with a voltage of 6-30 V , providing a current of at least 1 A. The electrode for welding is a graphite rod from used KBC batteries or others, sharpened at an angle of 30-40 ° . As an electrode holder, you can use a probe from an ampervoltmeter with a crocodile tip.
In the places of future welding, the pre-stripped conductors are twisted by a bundle additionally connected to one of the poles of the current spring. The electrode, connected to the other pole of the current source, warms the room to be welded. The molten metal forms a teardrop shape. As the graphite burns out during operation, the electrode should be honed.
With the acquisition of skill welding is obtained clean, without scale. Work is necessary in sunglasses.
