Soldering time
Soldering process time can be saved by preheating effect of N2 system. Look at the following graphs showing the soldering time difference with / without nitrogen gas in case of HAKKO FX-951 and HAKKO FX-838.

High power 150W soldering station suitable for soldering from large to fine components (Digital)for components requiring a large amount of heat |
HAKKO FX-951
| Test method: | Measure the time until the workpiece reached to 250℃ at 5-points; setting temperature is 320℃ with nitrogen gas and 340 ℃ without nitrogen gas.: |
| Board | Paper phenol copper, single-sided |
| Component | Connector |
| Tip shape | T12-D24 without nitrogen gas T13-D24 with nitrogen gas |
| Setting temperature | 340℃ without nitrogen gas 320℃ with nitrogen gas |
| Solder | Lead-free solder (Sn-3Ag-0.5Cu) ø0.5 |
*Please refer to above values, which vary depending on soldering condition.
