I'm looking for a safe flux (no fluoride) is there a type m and type l flux that has a safe formula?

What do you have holding the wire up while you solder

No - just no! When soldering, we need to make a secure mechanical connection before we solder - if at all possible. In this example it's not just possible - it's easy. So, with needle nose pliers we squeeze the lower j-hook closed, then squeeze the upper j-hook closed, and then solder. We are left with a tight mechanical connection and a good electrical connection. Solder has very little mechanical strength - the mechanical strength goes into the design before the solder is In electronics where nothing is ever going to move again - you can get away with the practice in this video, but it's poor practice. It this were two leads of a wire antenna outdoors, the connection would be broken before sundown if not secured mechanically first.
