WELDING INSTEAD OF PIKES
Electric welding significantly reduces the time spent on installation work, alienates connections that withstand high-temperature heating, does not require solders, fluxes, pre-tinning, allows you to connect conductors of metals and alloys that are difficult to solder, such as electric heaters.
For welding, it is necessary to own a spring of direct or alternating current with a voltage of 6-30 V , providing a current of no less than 1 A. The electrode for welding is a graphite rod from used KBS batteries or others, sharpened at an angle of 30-40 ° . As the electrode holder, you can use the probe from the multimeter with a crocodile tip.
In places of future welding, previously cleaned conductors are twisted with a bundle and additionally connected to one of the poles of the current source. An electrode connected to the other pole of the current source heats the room to be welded. The molten metal forms a teardrop-shaped union. As the graphite burns out during operation, the electrode should be sharpened.
With the acquisition of skill, welding is obtained clean, without scale. To work it is necessary in light-protective glasses.
