250g-500g 1/0.5mm Lötzinn Lötdraht Löt mit Flussmittel Lötkolben Lötstation DHL (WHL #68F1)

First things first. New batch, same naming scheme as before. Since I already measured weight per meter, I just picked one sample length from a (new) lead-free U1.0 wire and cut the others to expected length. 100cm of that stuff is 5.42(196)g, for comparison. […]
