However, the optimum tip materials. Activity of the halide activated versions on temperature and heat capacity required for a hand nickel is also good depending on the state of oxidation of soldering process is a function of both soldering iron the nickel finish. The good thermal stability of Multicore design and the nature of the task and care should be fluxes means they are also well suited in soldering exercised to avoid unnecessarily high tip temperatures for applications requiring high melting temperature alloys. excessive times. A high tip temperature will increase any tendency to flux spitting and it may produce some residue Cleaning: Multicore 400, 502, 505 and 511flux cored darkening. solder wires have been formulated to leave pale flux residues and to resist spilling and fuming. The soldering iron tip should be properly tinned and this Cleaning will not be required in most situations but if may be achieved using Multicore cored wire. Severely necessary this is best achieved using Multicore MCF800 contaminated soldering iron tips should first be cleaned Cleaner (see separate technical data sheet).
