How to Solder Flexwatt

Well I have a rack half complete, so I decided to stick down a sheet of flexwatt, put a tub on top, and placed another shelf on top of it. I plugged the heat tape into the thermostat, set it for 100, and it's STILL climbing, after 10 minutes it's only at 93. I remember in your video you said that an advantage to soldering is that it heats up much quicker, does this slowed heat-up time possibly have anything to do with my connections?? Thanks again for your help guys!

Its possible, How are you measuring the Heat tape and temps inside tub.

Heat tape has the thermostat probe (ve-200) taped to it, which is giving me the reading of the heat tape temperature, and a temp gun (zoo med) to measure all surface temps (I have checked it against a friend's PE-2, and it is accurate to that within a degree).

Are electrical connections an "all or nothing" deal (i.e.- electricity flows, or it doesn't), or can the amount of electricity they carry be affected by poor connections?? I swear I tugged hard and they stuck!

When i first wire up racks I only check temps once every hour as takes time for it to fully heat the tubs bottoms

Ahh okay, well thank you for your help! I ended up buying a smaller diameter solder so I can be more precise, and wrap the wires to prime them first. I figure I'll just re-do them just for the piece of mind. Thanks again!
