Jumper cable amp rating

[dr. d]

thanks! yung rosin ba sa ace din nabibili? i tried to do this before using the lead bar sa hardware (the one used sa rad) but the solder never stuck to the metal... i used a blow torch

the one in ace is fine.
the metal pieces you are going to solder together, have to be shiny. sandpaper them. the rosin helps the solder to stick to the metals. and the metal pieces have to be good and hot, for the solder to work well. that is why you need a big heat source, like a small blowtorch or an industrial soldering iron.
and there are some metal types you can not solder, because solder won't adhere to them.. aluminum, stainless steel,

to the guys who prefer crimped ends, the stores selling these cables may have such crimping tool to assist customers with..
