The Inerting Process

 All Wenesco wave solder pots and static pots can be inerted with nitrogen to prevent or reduce oxidation from forming at the interface of the solder surface and the atmosphere. 

  Nitrogen tank (or plant nitrogen supply) with regulator and gauge, usually set at 15 psi.

  Flow meter for the PUMP INERTER is usually set for 5-10 CFH.  The pump inerter is used specifically to eliminate black powdery oxides produced around the pump shaft.

  Flow meter for the WAVE INERTER controls nitrogen flow into porous tubes   which produce laminar flow across the   wave nozzle. This prevents oxides from forming on the wave surface in certain applications.

The nitrogen first enters the wave   control box where you may opt to permit nitrogen flow only when the solder pump is operating.  The flow meter setting depends on the size of the nozzle. We estimate 50 CFH on the average. 

  Flow meter for the POT INERTER controls nitrogen flow to the surface of the solder bath, eliminating most of the dross on the solder surface.  The flow meter setting depends on the size of the hole in the top cover.
