I’m looking for this exact same blow torch. I bought it 25 years ago. I’d like to get another one for back up. But... my online searches have come up with nothing. At the time, this was one of the hottest blow torches!
Thanks Jason. It doesn’t really have any name on it. It has these markings. VTK. B 9 And U.S. PAT.NO 4013395 I dug up my collection of blow (7-8) torches I have collected over the years, and this one is insane! I don’t have the TS 8000 yet, (I do have the TS 4000 and love it) but I do almost bet money this torch outperforms it. . It slides right into my Tuyere with the long straight tube. The naturally aspirated air hole is outside the furnace. It lights my diesel so safely I don’t even think about it. If I could get two of these torches, I think I might be able to melt aluminum (off grid) with no power requirements. The picture below is with the blowtorch valve full open only using a 1 pound tank.
The patent no on the torch refers to the way the assembly burns the gas. http://patft.uspto.gov/netacgi/nph-...XT&s1=4013395.PN.&OS=PN/4013395&RS=PN/4013395 The patent artwork shows a more traditional torch design with the valving aft of the mixing chamber and tube assembly. https://pdfpiw.uspto.gov/.piw?Docid...&SectionNum=&idkey=NONE&Input=View+first+page Uniweld sells a similar but not the same unit. Called a swirl head torch. https://www.grainger.com/product/5K...kwcid=AL!2966!3!254664894139!!!g!418279569562!
