How long can I use the 940 Glue Gun after its cord is unplugged?
在拔除 940 膠槍線後，多久可以使用該膠槍？
Depends on the usage, in general it takes about five minutes before the glue in its chamber cools down. But the Gluegun needs power to heat more glue and refill it's chamber.
視使用情況而定，通常需要大約五分鐘的時間才能讓腔室內的膠水冷卻下來。不過膠槍需要動力來加熱更多膠水並重新填入腔室內。
