Welddownunder

Hi to all This is a request for information on the advertised oxy/acetylene gun. It would interest me to know if any person has used it or seen a UK report on the gun, all the video information from the site www.welddownunder.com has been viewed, I would be pleased if some information external the supplier is available. Thank you for your interest silvercrest

Best I can offer is secondhand info.
The guy I talked to that had one, went back to his regular torch.
If you are welding larger items, your knuckles spend a lot of time very near the weld zone.
When cutting, even more so.
I've never used one, and like as not, never will.
Frankly, I figure the cost differential between a regular torch and this one, would be better spent on other things, perhaps a set of jewellers torches or some other tool that would see use.

Havent used one myself , but I am a member of an online forum where I'm sure I have read something about these torches . I have done some searches on the forum to see if I could find the thread , but to no avail.
Here is the link to the forum ,you are welcome to post the link to the torch on the forum an ask for any information on the performance of the torch http://www.woodworkforums.com/index.php
Hang on you say !!! That's a woodwork forum , well yes it is ,but it has a metal work forum also ,and this is where I'm sure I read the info on the torch .Just look along under the main header bar and second from the right you will find the metal work button .
Sorry I couldn't help more

"The conventional Oxy/Acetylene torch relies on swaged tips which roughly mix the gas after leaving the tip"
"The DHC 2000 Torch is totally the opposite, it has a precision mixing chamber inside the hand piece which mixes the gases at equal low pressure and low velocity before leaving the tip, resulting in an extremely narrow concentrated heat affected zone."
Both of my welding torches simply don't do that - like the DHC torch, the gases are premixed in the nozzle.
My cutting torch does (sort-of) mix the gases after the nozzle, but that's different.
Can't see the main attraction, but I haven't used one.

Many thanks to all who replied to the post.
Several hours have been spent since my post on the Internet via forums in the US, AU, UK, the main thread that has come through is that this is a old query that comes up from time to time with no firm conclusion.
It is my believe (possibly incorrect) that there an very few in the UK or the owners have no Internet connection or do not read news groups, and/or possibly choose not to inform anyone.
The end result is that someone has lost a sale.
Once again thank you all

That is the Dillon or Henrob torch. I have one and have had it for a fair number of years. A good torch for reasonably fine work (as opposed ot the big BOC Comet torch). The torch is fairly heavy and chunky, but it is easuer than my big torch for ali welding (but Tig is better still). The cutting torch sucks. Your hand is to close to the work, and you keep losing the cut with a lack of preheating, and it is awkward. I ended up buying an old Meteor cutting torch for cutting jobs. Much, much easier to use. Overall, not worth the premium against a lot of other torches on the market - I have a small Meco Avaitor Jet torch which IMO is just as good and lighter. Cutting torch is much better as well. Geoff

This fits what I was told.
Get a decent "Aviation" sized welding torch body and tips. These were originally sized to weld aircraft frame tubing together, and get into tight corners. Light and maneuverable.
Then use the money saved to stock the toolroom! Mucho price differential!
