Thread: Flux for HMP soft solder?
13/11/2009 12:03:46
Thank you all for the above replies.
 
I have not tried Bakers fluid but I suspect that John is right.
 
JasonB's reply looked promising but Reeves told me that they have dropped their flux for Camsol, presumably Thessco SC5, and I have been unable to find any information of stockists.  Also Cup Alloys only do a general purpose soft solder flux, which may be OK, but can't send it by mail - "collect only from exhibitions" is stated and there are no exhibitions in East Sussex attended by them that I can find.
 
So, can anyone tell me more about Thessco SC5 availability, please?
 
Thanks to all,
Graham

Thanks for that Geoff.  I am glad that I am not the only one having this problem.
 
Yes, I have tried Powerflow which as you say doesn't work.
 
In fact it was Chronos who recommended Fluxite and Carrs Green label which also didn't work.  I asked them after unsuccessfully trying several of the fluxes that I use for plumbing work.  Hence the posting as there must be something suitable around.  After all HMP solder is readily available and mine does have flux cores maning it usable in fery small blobs!
 
Regards,
Graham

Hello all,
 
Can anyone recommend a flux suitable for use with HMP (about 310 deg. C) soft solder?
 
Having been a Plumber and heating engineer for over 40 years, I have no trouble at all with the lower melting point soft solders or indeed silver soldering and "spelter" brazing as I have suitable fluxes.
 
I have however yet to find a flux which actually works with HMP soft solder.  Fluxite and Carrs Green Label have been suggested to me and tried but I found these to become exhausted before the required temperature was reached,  Silver solder fluxes, on the other hand have a too high working range.
 
Many thanks,
 
Graham
