When the pump starts heating, it uses 1400 Watt; once it has reached a definitive level, this is reduced to 700 Watt, then to 350 Watt until it uses 175 Watt.
With this energy rate it can maintain the required temperature.
The advantage is: less energy needed for use.
With the necessity of changing the bucket containing the glue a small temperature decrease takes place, the pump loses about 3°C which is recovered with the use of 1400 Watt in a few minutes; on the other hand, devices currently on the market have a variation in temperature of 9/10° up to 12°.
With the use of 400 Watt it would take more than 20 minutes to go back to the previous temperature, but using this pump it takes less time to reach the required temperature.
The advantage is: less loss of time.
