Bronze brazing

Hi just posting some photos. Was playing with silicon bronze on flat, was ok so thought to do it on an edge. Only prep was wire brush, yes thats surface rust on sched tee. 2 tees joined with a crap, hot, attempt at walking cup. Not a cup walker......yet.
So on bevelled pipe tee edge. 1) at Jody's 33 rule on pulse. Except 86 high 33 low. Was 100amp high but moved it down and too lazy to change 33.
Went ok, really ok but had to find a way to replicate result on straight dc as my snatch pack is a 180 inverter with a vavled 17. So 57amps no pulse. Thoriated, I went back to thors and having no issues like what I had with Lanth goldies. With silicon bronze Im only a few hours in, maybe 8 or so. I think it went ok maybe a bit of parent melt, it felt like it once or twice but couldnt see it in the finished result, but if any one has any tips feel free. I dont even care if its unkind ish. Cant fix if I dont know.

Thanks Tweake, its better to work with than I thought it would be.
I say 8 hrs but the pipe ends were 2hrs and worked pretty well straight up. the other 6 were tuning settings on flat and verti up. I didnt include the time watching Jody, mr tig and millerwelds browndog welding. would have been chasing my backside without the vids. was suprised at cost though. 5 dollars a 450mm stick at bunnings, my LWS got the same brand in at 700mm sticks $1.19 each. go figure.

yeah you don't buy consumables at bunnings. (tho their gas is way cheaper than BOC).
i think my local shop its $60/kg for silicon bronze. i have some here tho have not had much chance to use it.
