Some one from the MM site had sent me an email question, I hit delete and itis gone please resend the question.

The Henrob is an oxyacetylene torch. Your advertising is misleading:

Oxyacetylene flame temperature ranges from 3000-4000 degrees. A plasma arc operates from 30,000-50,000 degrees. There is quantitatively and qualitatively no way for the Henrob to "cut like plasma" with oxyfuel given these temperature differences.

If you want more facts about plasma, or just a quote, try 800-932-8312.

Mike, I completely agree that the Henrob/Dillion/DCH whatever is an OA device. I've owned and used one for 6 years. I'll have to take your word for the temps and stuff, I don't have a clue, I just know it works. I also have a Miller 625 Plasma Cutter.

In the "RIGHT HANDS", the Henrob will indeed cut at least as nice as my Plasma. And it will cut much nicer at the 'sever' thicknesses of my 625 which is 1/2". I've even cut 3/4" with the Henrob with less pretty results but the 625 won't touch it. Therefore I don't think the advertising is misleading at all.
Now, for the qualifications. The Henrob takes some practice and experience to be proficient with it. A chimp can operate a plasma with a drag tip and the plasma cuts at a faster inches/minute.

For the past couple years I used the Henrob frequently to cut long angles in 1/4"-1/8" rectangular tubing for legs. As I said eariler, it takes some experience to make a nice cut and I was unable to get my son to master it quickly so I got the 625 and made a template so he could cut the legs and free me up to do other things.

In addition to cutting, the Henrob is a dandy little torch for welding. Again, takes some practice to master.

If I could only have ONE cutting/welding tool, it would certainly be the Henrob and it does indeed, "cut-like-plasma". Certainly, the process is different but the result is what is important imho.

Mike,

I am not trying to be a smarta$$ so please do not take it that way,

Please send me an address and I will send you a piece of metal that has been cut with the Henrob/DHC 2000 and you will see the quality of the cut first hand.

If you have never seen it cut you should not dis-credit it or me by making the above statement.

It is not the same process however it gives VERY SIMILAR results which is what the customer cares about not HOW.

It DOES cut steel up to 1 inch thich as good or as some of my customers say, BETTER than their plasma cutter.

The flame temp is 5880 - 6300 deg.F of a conventional torch and 600-900 deg.F higher with the Henrob/DHC2000 torch due to it's advanced mixing chamber.

See
http://www.encyclopedia.com/searchpo...tylene%20torch
and
http://hypertextbook.com/facts/2002/...yCheedie.shtml

The flame does not cut the metal so the flame temp is kind of irelavant the oxygen reacts with the ferrite in the steel @ around 1000 deg.F and basically oxidises the metal at tempratures of around 10,000 deg.F
With that said the oxygen is doing the cutting,not the flame.

Have you never seen a torch cut metal and the flame be extinguished and the cut keep taking place?

hi mike,
your comments about jim making misleading claims is just wrong!!! i have been able to make cuts with the henrob that were every bit as good as a plasma. next time you call someone out on the carpet maybe you should actually have knowledge of both the processes you are comparing.

In a pinch, if my cutting torch isn't handy, I'll cut steel with a regular torch tip by just getting the metal red hot and then cranking up the O2 supply. It will cut.

The beauty of the Henrob is the narrow flame and narrow O2 cutting stream. The kerf is quite small and clean. It definitely cuts more cleanly than my regular cutting torch.

Frankly, I like the Henrob better than the Plasma torch. The best feature in addition to its clean cut is the low cost of consumables. I can buy a lot of O2 for the cost of the cups, tips and electrodes. Electricity isn't free either.

Did not intend to raise hackles, but coming from the machine cutting side of the world, I look at the accuracy of the cut, the tightness of the kerf edge (90 degree edge with our SilverEX electrodes), as well as the cutting speed. How many inches per minute are we talking about? I'm sure the Henrob can do some quite beautiful work, but can it cut that beautiful cut as accurately or as fast as plasma?

[Avalonjr]

No hackles raised here, just providing some feedback.

For me it comes down to quality for price. If I can afford it and justify it, it is in my toolbox. If it does great work, but it's price isn't justified, then it isn't in my shop and of no use to me. I won't be cutting thick metal very often, so there isn't any point in spending $3K for a high amp plasma cutter when a Henrob "Cuts-like-Plasma" and I already have one.

Just my 2c

I am planning on buying a Hnrob for many reasons. Its cheaper and it can heat, weld, and cut metal. Try doing that with a plasma.
