Thanks for your reply.
I need to solder items that need only about 10 seconds to be heated and soldered ( no longer)
The starting temperature can not be ambient (20°C)temperature because it is not technically possible to heat up ( large) soldering tip to about 220C during those 10 sec. So I must already start from a higher temperature, say 150C. That temperature is lower than melting point of tin but high enough that soldering tip CAN reach the melting point during those 10 sec. After those 10 sec, I need to a soak period to cool down the soldering tip but ONLY to those 150 C from where I started (and I can solder other items)
Will I need 2 controllers, 2 pcs of TC or only one?
Thank you
