I guess this thing is to weld plastics, and seem great to do thin tanks,
since the working space isn't enough. But from the explanation 'a
voltage is attached between the fixed Heating-Welding-Rod an the
neighbouring parts' Where is the other connection done? the heating
resistor has only one wire???
About chemistry, i am to in a fight between finding the good one to have
at home, what them are and prices, i think heaven found a way to mix the
bungard palladium based chemistry (Ethanolamine+PEG;NaCL+HCl;Pd+PVP
+HCL;K2CO3) at home using palladium bullion coins as source of palladium
(palladium metal+nitric acid+EG+PVP+ultrasonic stiring or NaOH), but
isn't more cheaper do it, and is a chemistry that need much rising water
and a water treatment system. After various readings i am now more in
the wish if a simplified version other german chemistry (polythiophene
based) will work, just the permanganate desmear and a PVP bath as
activation, since this can be just drain without problems. But i don't
know if the PVP will just bond to the MnO2 treated resin.
My question: how will you Chris treat your rising water?
