thanks again for reply, we have now configured speed of traveling so pcb can travel through preheat with one speed (call it v1) and through wave with other speed (call it v2). Lenght of preheat elements is fixed, so with speed v1 we can change pr

Are you using water based flux? Any preheaters on the SS machine?

Sue, It may be a thermocouple problem or the PID heater controller. Check with the wave machine mfg.'s tech support.

Forced Convection delivers the most efficient thermal transfer.

I agree with Erv. That is the same combination we use and it has served us well.
