Nitrogen improves the quality of each solder joint because it provides additional heat and prevents the tips from oxidizing. The flow regulator regulates the nitrogen flow to the soldering tip to optimize consumption. The nitrogen flow is activated as soon as the T245-NA handpiece is removed from the stand. The flow stops as soon as the handpiece is returned to the stand. The flow controller requires the GN-A nitrogen generator or an existing nitrogen supply. - Flow rate controller for N² operation - requires nitrogen generator GN-A or another nitrogen supply - for control unit:DDE/DME, type MNE-A - 1 nitrogen flow controller - 1 connection cable - 1 operating manual
