Re: Is too much wattage a bad thing?
I agree. Ramping up the temperature too fast will cause the powder to melt before the item surface gets to temp. Poor bonding is the result. However, having enough wattage to heat the space efficiently helps the controller maintain an accurate temperature during curring.
Unless you're familiar with the PID controller concept and programming, setting the parameters can be quite complicated. Most simply use the Auto function. In this mode, the controller needs to see temp changes within a certain time frame based on it's own calculations. Lower wattage ovens will suffer with lower accuracy and can even timeout. The best design is to use available calculators to determine the wattage needed to accurately heat the oven space within about 30 minutes. This gives most items time to reach adequate surface temperature.
