Low-temperature copper and aluminum wire copper and aluminum rod M51 179 degree temperature copper and aluminum wire copper and aluminum rod reminder: WE-M51 wire from genuine Weiou Ding (Tianjin) Welding Technology Co., beware of imitations! Welding works: 1) heating the base metal to be welded. In order to achieve better results of the two metals connected two metal while heating, but heating the copper-based, should not burn the high temperature, because the material's melting point and the melting point of the solder was 200 degrees, if the high temperature burn flux plus will go black. 2) get rid of the metal tension. Get rid of the metal surface under the effect of M51-F solder copper and aluminum metal tension, this process can be, there are two ways, one can first cast a little M51-F flux in copper and aluminum base metal welding, heat gun with a porous base material (Note that at this time do not use fire to the M51-F copper and aluminum flux, mainly by the thermal conductivity of copper and aluminum to make M51-F flux violent boiling) until M51-F flux can be less vigorous boiling M51-F copper and aluminum wire; another can not be put on the base metal welding flux, can be directly heated and then dipped in copper and aluminum wire welding flux under M51-F with M51 copper and aluminum wire. 3) If the surface temperature enough, will be forming a very bright white seam, natural slow cooling, wash with warm water and residual surface M51-F flux
