Hi.
I saw (around the web) that many peoples are using their hot air gun
to blow hot air into a carton-box (300°C position) and turns the
carton-box to a kind of oven, in order to cured painted object
etc. (See attached photos from youtube)
The temperature target inside the carton box is about
160°C-220°C, so the heat gun is turning-on until the box reaches
to 220°C, turns-off until it go-down to 160°C and turn-on again...
(in total 30 minutes).The hot air gun stays the same position all this time.I understand that this process may damage the heat-gun.My question is what parts in the heat gun may be damaged/degraded?Since that during the turn-on moments,the blow air can go-out through the bottom of the box(the box is not sealed at the bottom),i assume that the damage may happen during the turn-off moments,while the hot air from the box(220°C)will go up through the heat-gun tunnel and damage/degrade something on its way up,but what?Does the plastic fan can melt/deform on 220°C?Can the fan motor may degrade?etc...
Thanks.
