8 g copper makes a good 250w soldering iron tip.

I had to buy 5 ft of 8g copper, $3.11 plus tax for a lifetime of soldering iron tips.

I got
Soldering at yardsale $2.
It needed a new tip.

Montgomery Wards house brand, They handled some good tools. I think I still have a few wrenches from there.

Spend some that money.

What are you thinking, I'm cheap.
$2 for a 250w gun and $3 for 5 feet of 8g copper.
What are you thinking??
You want me to spend over $140 for a soldering iron?

I used silver solder when changing an AC compressor.
I needed to use an acetylene torch to get the copper hot enough.

Why not use rosin core lead when soldering copper wire?

You can not take it with ya.

I just thought I would throw bearing solder in to mess with ya and you know that.

BTW no one likes a cold solder joint : ( I run across a wire like on a O2 sensor plain solder does not take to kindly.

BTW silver solder melt range is around 1100 deg.
Bearing solder mid 450 deg. range.
Solder has got to wet the joint are its a cold solder joint : (

I was surprised to that Sta-brite has no melting range. 430 deg, melts and completely liquid, cool to 430, solid. weird. But nice to use.

Hobo, have you used it on vehicle tubing? I'm making up some hard lines to install full flow filtering on an old flathead Mopar. It would be much easier than my plan to use silver braze.

I remember when silver solder was a dollar a 1 oz stick, $16 dollars a pound. Then the Hunt brothers messed up the silver market. Don't remember what happened to the 2 men.

My thoughts and what I have read on the internet.

Sometimes using silver bearing solder (6% silver) is
better than brazing. Brazing can (sometimes) weaken the
parent metal. Silver bearing soldering is not silver
soldering. Silver bearing solder flows around 430F, whereas
silver soldering melts the filler around 1,100F, so it is
really silver brazing.

Silver bearing solder. It wets to a lot of different materials. Don't
confuse this process with silver soldering.

Consider Harris Stay Brite (6% silver) silver bearing solder
for difficult materials, and or when additional strength is
needed. This is not silver soldering. Stay Brite flows @
430F. Silver solder melts around 1,100F. Louie

Sta-brite 6 or 8 is what is was considering. I have some silver/braze rods but the sta-brite sure looks easier.
