Hi    I've been looking around at cutting torches on the internet. And I've been wondering why some torches come with a 75 degree angled head? Is it just a personal preference to some people, or is there a special purpose for it? Most of what I've read about using a cutting torch says to keep the tip perpendicular to what your cutting, which makes sense to have a torch with a 90 degree head. But a very few articles recommend a 20 degree angle while cutting. Maybe someone could enlighten me, since I could not find any info about this subject on the internet.  Thanks
Reply:Cut standing up, long reach etc.
Reply:I used one for many years to bevel pipe. For  a few bevels on pipe it's much faster than rigging up a beveling machine. If you are good with a torch there isn't much difference in the accuracy of the cut.
Reply:i would disagree on the perpendicular. try it with  the torch pointing a bit in the direction of travel, putting the heat where you are going to be cutting with  the ox stream..
Reply:Thats what Esab recommends; angling oxygen stream toward the direction of travel and increasing the tip size one or two sizes larger . They state that the cutting speed will be increased substancially.
Reply:Cutting technique is still the same. The angle of that head is just for your ease and accessibility.City of L.A.
