ok i jus picked up a 30 watt all purpose soldering gun along with some .032 diameter standard Rosin-core solder. i jus tried to solder some bars together and it sems as if the solder isnt sticking to the metal, like il get it attached to one bar, and when i try to bring it to the other bar to join them, the bead of solder resin jus slides off the metal. whats up with that? its kinda like tryin to paint on a wet surface, it jus bubbles up and runs. what am i doing wrong? what do i need to do?

try puting a bit of solder on each bar(this is called tinning) and then try soldering the two together.

do you have the right kind of soder?? there is alot of diffrent types there

yeah your right there, i use multi core solder

 

[Riggs]

maybe get some sand paper and scuff up the metal a little bit .. so the solder can stick better

 

[ice64berg]

make sure your getting both pieces hot ... sounds to me like your trying to get it together with cold soldering

also like homeboy said tin the pieces ...

yea i tried to put a little bit on each bar and binding them together but once i did that it balled up anf fell of both bars.

mabey get thicker solder?

all i know about the solder wire is that its a standard core solder, and that its .032 dia. wich is a lil thinner than a paperclip.

ill try to scuff each piece and see if that werks

with my welder, i have to use this little creme, i put it on the bar, heat it up wit the solder until it boils, and then weld the bars.

 

[b_boy02000]

ok yea it still aint werkin. what type of solderin guns you got? is it the one with the bent wire tip or the spear tip? i got the spear tip one. could tht be the problem?

 

[hopper_ali]

try glue the bits together and then soldering

 

[WgRyDaZ]

Make sure the bars are not aluminum....solder dont dont stick to it...well atleast threw my experiances.

Make sure you are not usin' electrical solder. You need solder for metals.

 

[BigPoppa]

how thick is the metal? The important part isn't so much getting the solder hot, it's getting the metal hot and then that melts the solder. If scuffing it up and using a little flux to clean it doesn't help, I don't know what's going on

well that was my prob wit solder i was using electrical solder to build a rack for my batteries and pumps :uh: i gave up lol time ta get some new kind of solder :biggrin:

 

[Joker808]

use non-rosen solder

 

[b_boy02000]

the gun is an all purpose soldering gun so i may be able to stil use that. i think ill go back to radio shack tonite and see what other kinda of solder material they got. what is the difference between the Rosin core and the non rosin?

 

[1ofaknd]

i think there is acid core, which is for soldering metal and steel stuff...not real sure though. the rosin is made into the solder to clean the metal before you solder your electrical connection

 

[b_boy02000]

yea arite, it does solder wires and stuff to metal, so i gues ill go pick up some different stuff

 

[Joker808]

go to a automotive store and get solder made to repair radiators
