Nitrogen Nozzles
Soldering and Desoldering Tips
Hakko offers nitrogen nozzles for N2 soldering, in which nitrogen serves as a shielding gas to protect the solder joint area from oxidation. The range covers nozzle types A (B2706, B3121), B (B2707, B3122), C (B2708, B3123), D (B2709, B3124), E (B2898, B3561), F (B2899), G (B2900), H (B2901), I (B2902), and J in KF format (B2923). The B2xxx series fits Hakko FX-791/FX-792 N2 soldering iron modules; the B3xxx series is compatible with T14 N2 soldering tips. N2 soldering reduces bridging and improves wetting on lead-free alloys.
