For soldering nichrome, the guides recommend a special activated fluxes TRL-1 or TRL-120. Not all are available. Where to find a replacement? Suggest: in the home medicine Cabinet. Check it aspirin. He successfully replace deficient fluxes, because the medicine is acetylsalicylic acid. Under the hot tip of the iron it melts, wets nichrome wire and easily dissolves oxides on its surface. Treated with aspirin wire should be tinned with stinging, but in a rosin to remove excess acid and prevent further destruction of the metal.
Attention!
Upon melting of aspirin are allocated corrosive gases, so working with him should be in a well ventilated area, under a fume hood or outdoors.
