I used Hi-Heat for years. No trouble. I loved that stuff.I'm using whip mix soldering investment. Anybody else using this?

I think they have a product called Speed-E for soldering too. It's been a long time since I had to solder.I found out that 2 kind of soldering investment from whip mix. Soldering investment and hi heat. Previous metal manager ordered soldering investment. I need to try hi heat. I guess hi heat is the right one for c&b work.

High heat soldering investment or use regular investment for ceramic alloys using straight water, no special liquid. Margins must be covered up with joints totally open...I only have 2 options for rocking framework. Hammer or solder. For me soldered bridge fits better than hammered one. Success rate of 80%.

Do you cut a groove in the investment at the solder point to direct the flame? Do you preheat the bridge enough in the burnout oven first? After burying the margins, and getting the lowest flame for the shortest time, I'd found those to be the issues.Oh no melted margin. Slightly lifted margin interproximally

Yes I do make channel under cut bridge. Bench set 20min and PREHEATING 1700F for 20min. BUT LOWEST flame for shortest time? Which one is more important factor? Flame temperature or soldering time? I'm not sure.Do you cut a groove in the investment at the solder point to direct the flame? Do you preheat the bridge enough in the burnout oven first?

All I'm trying, badly, to say is don't overheat. Think of it as casting. Yellow high Gold content takes much less temp/time than Palladium based or NP. With solder, just use as much as you need and stop. It'll take all you out on/in. If you need to, practice on throwaway stuff that someone already shyed up or something. Another option would be to post-solder in the porc furnace, which is tricky itself because you can't see or intervene if you didn't put enough solder.Yes I do make channel under cut bridge.

I think minimum amount of solder works best tho. I mean the solder strip/wire amount wise.
