oxy/LPG welding
« on: October 01, 2010, 08:56:10 am »
does anyone here use these gases for soldering/silversoldering. just a query or two about it. can you use acetylene regulator for it and i have read that you have to countersink the welding tip before use. is that true.   {:-{ {:-{

Hi, I use propane & oxy for silver brazing & small stuff welding. Use a propane gauge, mine is ruby red in colour.
 Do not get mixed up between silver solder ( which is Hall Markable) and silver brazing ( which is not ).

Hi again, In welding it is the norm to prep the edges to form a V and you always fill the root of the V first before filling in rest of the prep.  Nemesis

 Yup, I've used propane through my acetylene torch, with oxygen for silver soldering boilers. Works very well. Lot cleaner than acetylene.
