ok I was serious about seeing if I can hook my LPG Oxy set , oxygen regulator to fittings I could connect to the compressor . Turns out I don't have the right fittings around here so I'd have to buy some . Just before I do has anyone tried this and knows it won't work ,hate wasting money on shit I can't use

Hello all,

More homework done to clear things up a little.

The Silbraze no flux 15% rods are expensive. Best i could get them for with a borrowed trade cash account was $24.75 for 750mm x 2.5mm. I'm told by actrol they are great but too dear for my pockets given I've a pile to finish off.

KK so of all places found 15% Consolidated Alloys rods at Bunnings $4 cheaper than anywhere else $14.96 for 750mm x 2.4mm @15%. Brown coloured tagged rods.

The Berzomatic TS8000 and TS4000 guns I notice new packaging now have a recommendation for brazing only to 1 inch.

Got a new design pot hybrid that will get the 15% treatment this arvo...looking forward to it.

Still looking for a Oxy/LPG brand set recommendation if any one has one.

G'day BT1,

Get the product sheet for those 15% rods and make sure there is no cadmium in the rods. A lot of rods do contain cadmium instead of lead.

Been a couple of posts on here about dangers of working with cadmium containing brazing rods, but I don't feel that it has the same publicity as lead dangers.



Cheers, Heffers

EDIT: These rods look ok - contain only silver, copper and phosphorus. http://www.cagroup.com.au/files/Brazing-Alloys-MSDS.pdf

Hello all,

just finished 2 tricky bits as a test in 2" using the 15% rods and Mapp...it flows beautifully and it's taking up spans over 1.5mm for filling as well... what a relief after using those bloody 2% rods for years...it a pleasure to work again.

The 45% rod is like butter...I can't believe how easy it is...

Perhaps those 6+ part builds will be 5+ with the completion of a new Hybrid pot design this arvo...

thanks all...back on track


A happy bt1

Well I just tried hooking up the compressor to a LPG/oxy colt sort of works . The flame gets hot enough to braze with for sure turned copper red hot in no time , the problem is the flame tends to blow it self out easily . it works fine while you are working close up on something but as soon as you take the flame off the job it blows out . I might play around with the settings a bit more before I decide if this is to much of a pain to use

If you have a spare nozzle or tip try to counter sink or concave the hole slightly.
Apparently this can help....

Cheers I'll see how much another nozzle is if not too much I'll give this a shot and post how it goes :handgestures-thumbupleft:
