I did an inquartation today, 125g gold 375g silver, lots of borax/soda ash and some nitre.
Tried the brazing tip, on neutral flame, almost an hour already, no melt.
Tried the cutting tip, on neutral flame, 10 mins at work and the nozzles where showing signs of carbon build-up. I was able to fix this by increasing the acetylene pressure.
Took me about 20 minutes to melt the 500g lot.
I do not have a rosebud tip yet. Does any of you have one? What was the maximum lot you melted and for how long?
I ask because acetylene should not be used for more than 1/7 of its capacity per hour. And we are talking minutes here.
Would I be better off with propane/lpg and oxygen tip? Propane/LPG produces more heat output per BTU but at lower temperatures.
