Fluxing

Proper fluxing is essential. Enough flux, either from melting of flux-core solder or adding M-Flux AR separately, must be introduced to assure complete wetting action. This is particularly important with +570 deg F (+300 deg C) solder as there is an increased tendency for the flux to be boiled away at higher temperatures.

If "spikes" are produced instead of smooth beads, it is a sign of inadequate fluxing, dwelling too long with the iron, and/or an improper iron temperature.

Rosin flux should always be used in making connections to Option S gages. All flux residue should be thoroughly removed with Rosin Solvent .
