I had one of those Solid-Ox welder outfits, just like the one in the video. Don’t get too nostalgic for one. I could do some brazing with it, trying to fix my Swiss-cheese-rusted 1968 Mustang. You had to get everything ready before hand, light the oxygen pellets, wait for the gas pressure to stabilize, then you had a few minutes to braze before it went out. It never really got hot enough to weld with. I tried every cheap welding device made, because I was a young man with big ideas and no funds.
I have a regular Oxy-Acetylene outfit now.
