advantages and disadvantages of electric glue gun and manual glue gun when playing glass glue, sewing agent and nail free glue?

The advantage of the electric glue gun is that the glue speed is relatively fast, which is more suitable for the professional construction teacher to use, because the construction teacher should consider the timeliness to improve the work efficiency. The advantage of the manual glue gun is that the glue speed can be adjusted, which is very suitable for the first time to use. The disadvantage of the manual glue gun is that the speed is slow, and the long-term play is more tired. The glue is not as uniform as the electric glue gun. I hope this suggestion can help you!
