 we are intrested in small reflow ovens for workshops, to remove the need for soldering smd with cheap irons.

 it takes 12DCV 5A ramping up\\
 when it reaches 410C (rated at 400c) it stabilize on 3A
 this allows for relatively precise ramping using current control.
+using a benchtop psu or lm317(?) you can make a very simple reflow profile.\\

-i was shocked by the low temp i couldn't believe my eyes and kept ramping the current to 220 :)
