    Never heard of it before, I wonder how much it costs. Looks like you have to call
    them to find out.

      A base rig is ~$1100.

        Do a search here on it...there was quite a stir a couple of years ago.

          I can buy a lot of acetylene for 100 bucks. My only gas axe use is brazing and loosening rusted bolts. The plasma has taken the place of the torch set.

          I woked for a large machinery salvage company for a number of years. They dismantled & scrapped (reduced as Petrogen likes to call it) press lines for the auto makers. I did the hauling but I was always around (to watch....) plus I got to run the cranes when I wasn't holding a steering wheel.

          They used phosporus/oxygen lances to cut with. No bottled gas, no bottled oxygen. They used a portable gasoline driven air compressor on wheels (like runs jackhammers) and the lance. The lance is basically a sacrificial length of steel pipe loaded with phosporus rods (like kids sparklers but longer and larger). You use a gas axe to ignite the rods and then you apply compressed air at the back end. The phosporus burns at who knows what temperature with the compressed air driving it but I've witnessed cutting of 3 foot thick, solid steel bolster plates like butter.

          They sound like a jet engine (ear protection required) when ignited and it's hotter than **** (fire retardent suits required) but it cuts and cuts fast.

          I don't believe the Petrogen can match that. It's not a clean cut, it's dirty but it's scrap.

            There is a place for the Petrogen, if I was in the heavy scrap business I would consider it, something like shipyard. 100$ in acetylene goes quick, I cut some scrap a while back and was being lazy where I didn't hook up an LP bottle, big mistake.

              Most scrappers still use propane. The company I work for (part time, I retired from full time 3 years ago) not only is intwined in a mini mill, but got into the front end as raw material (scrap) processors. They handle the front end, do re-melt and then process the slabs into HR and CR products as well as structural. They are the largest metal recyclers in the country now.

              They still run ganged propane and ganged O2 tanks for heavy reduction but the reduction machinery has evolved to the point that most metal can be shreeded and processed untouched by human hands...or cutting equipment.

              The gas torch, to them, would be a specialized unit, not considered a general use tool. I'm sure they have looked at it. They tend not to leave any unturned stone in their quest for economy of scale. After all, that's how the business operates.

              If I was cutting heavy gage on a regular basis, I would consider one just to eliminate the dissolved acetylene bottle. I'd still need the O2 bottle but I use the plasma for 90% of my cutting now and I'd still need the acetylene for high temperature brazing, which reminds me...I have a job in the shop that needs to be brazed this weekend.

                thermal lances? those things burn at around 10,000 degrees Fahrenheit or more (i think)
                now they use steel rods, not phosphorus.
                Always assume every project you take on will take twice as long and cost three times as much as you estimate.

                  i think the benefit is that the fuel can be pretty cheap.
                  but, if you want a gasoline-oxygen rig, there are many alternatives, some of which you could build
