Does the Oil-Wax Heater (Melter) maintain a constant temperature at the level required?
Yes, but you need to keep notes on the first few batches and mark the dial indicator. The water jacket provides an even heat and helps provide a regulated and constant temperature, but remember, you should try to maintain a fairly constant room temperature. A fluctuating room temperature will make it difficult for your thermostat to control a constant water jacket temperature. An insulation jacket can eliminate these fluctuations.
