Why does the HENROB 2000 Cut steel better than a conventional torch?

FAQs on the DHC 2000 / Henrob 2000 oxyacetylene torch
The concentrated and hotter flame transfers heat to the steel only in the areas needed to preheat to the cutting temperature not a larger area like a conventional torch which uses 4-6 preheat flames we only use 1 in front of the cutting tip. Separate cutting and flame tips are used with our system.

Why does the Henrob 2000 weld cast iron better than a conventional torch?

FAQs on the DHC 2000 / Henrob 2000 oxyacetylene torch
The low turbulence and oxygen content along with the clean burning characteristics of the flame is less likely to introduce oxygen/carbon contamination into the weld puddle which causes a hard weld and possible cracking.

Why will the Henrob 2000 weld aluminum better than a conventional torch?

FAQs on the DHC 2000 / Henrob 2000 oxyacetylene torch
The mixing chamber reduces the turbulence and oxygen content (almost none) in the welding envelope at the tip of the flame so it acts as a shielding gas. The rods required are standard TIG rods; you must match as closely as possible the alloy of the rods to the alloy of the metal being welded. NOTE: A special Lens is required to remove or reduce the prevalence of the yellow/orange flare caused by the sodium/fluoride in the flux. Oily aluminum and used castings e.g.

Are there any applications where a MIG, TIG or Conventional Torch are better than the DHC 2000?

Welding Down Under
Yes. (and so there should be at about 10 times the cost). In the following situations MIG is doing exactly what it was designed for and does it superbly. Eg., Where the MIG is set up to work continuously all day on the same settings, it is the fastest welding process we know of. Please Note .

Why is the DHC/Henrob/ Dillon torch any different than a conventional oxyacetylene torch?

FAQs on the DHC 2000 / Henrob 2000 oxyacetylene torch
The Mixing chamber is unique. It mixes gasses differently, in EQUAL volumes and pressures (4psi.) each with an injection type-mixing chamber, In doing this flame burns more efficiently producing a hotter flame with less oxygen or carbon contamination of the weld or cut. The temperature of a conventional oxyacetylene torch may vary from 5850 degrees F to 6300 degrees F according to many factors, such as gas purity and mixture.

Can the Henrob 2000 be used on a CNC cutting table or used to cut circles?

FAQs on the DHC 2000 / Henrob 2000 oxyacetylene torch
These are areas that you must follow the flame with the cutting attachment so the machine must be programmed to rotate the torch to keep the tips in the proper perspective.

What is the difference between the DHC 2000 and a conventional Oxy/Acetylene Torch?

Welding Down Under
The conventional Oxy/Acetylene Torch has a wide heat spread, this is because it mixes gases externally from the tip. By centrifugal force atmospheric oxygen is also sucked into the weld area due to this whirlpool action. This action combined with high gas pressures create a set of conditions which make welding very difficult, particularly on thin materials and easily leads to distortion and collapse of the job.

What size torch tip should be used to cut rusted steel?

FAQ - Watertorch.com
We recommend to remove any rust. If you are cutting rusty iron, the BG will do it more reliably and with less spitting, popping and missed cuts than conventional fuel-gas. We recommend using 'flush' type tips. 'Recessed' tips will heat up because the flame will touch the metal. Assuming you are using the Victor brand of torch: Use a #0 torch-cutting tip for up to 1 inch of steel (sometimes thicker).

What metals can be welded with the Henrob 2000?

FAQs on the DHC 2000 / Henrob 2000 oxyacetylene torch
The only metal we know of that can not be welded is titanium, I’m sure there are some specialty alloys that can’t be welded but, Most of the metals on cars or trucks is fair game with the exception of HSLA steel on unibody cars which it is not approved for (It will do it but is illegal in most states)

Can the Henrob 2000 be used for Brazing and Soldering?

FAQs on the DHC 2000 / Henrob 2000 oxyacetylene torch
Yes the cleaner burning (low O2 content) flame usually makes brazing and soldering easier by reducing or eliminating the need for flux, The kit even comes with an air-acetylene tip, which is like a plumbers “Turbo torch”, however most people prefer the normal welding tips. The hotter, more concentrated flame allows faster heating of the joint to be brazed or soldered so less heat transfers to unwanted areas sometimes reducing or eliminating the need for heat sink compounds or devices.

When do I add oxygen to cut steel?

FAQ - Watertorch.com
You have to wait for the steel (iron) to be at oxidation/ ignition temperature. Usually this is when a few little sparks are flying out. If you add oxygen too soon, it will 'cool' the iron, instead of causing it to burn.

Is Microfresh better than the conventional system I use now?

FAQ: Frequently Asked Questions by Microfresh, © 2007
Conventional aerosol dispensers use heavy droplets that cover perhaps a ten foot square area for up to ten minutes. The Microfresh air treatment does not use heavy droplets. Its micron-sized particles are so light, they float and uniformly spread throughout the space. In fact, Microfresh particles are 1/50 the size of aerosols particles. And Microfresh only uses 1/125,000 as much liquid!

Line on a spinning reel runs through a right angle turn, across the bail, to get back to the spool. The line revolves around the center axis of the spool. You can't keep a finger on the line as it comes in. Any weight or impact or change of tension has to be felt through the reel. On a conventional, you can keep a finger on the line, if you want, and there is no revolving right angle turn to muffle sensation. You'll feel more of what goes on at the end of the line.

Which are better, stainless steel, porcelain-coated cast iron or porcelain enamel cooking grates?

Welcome to Weber.com
All have their merits, so it is mostly a matter of personal preference. All require little maintenance and give great sear marks. Porcelain-coated cast iron grates will hold the heat longer so you don't have to cook with higher temperatures. Stainless steel grates have a longer warranty, followed by porcelain-coated cast iron, then porcelain enameled. Replacements are readily available for all styles. Note: If you have porcelain-coated cast iron grates, no seasoning is required.

Question - How thick a sheet of steel will plasma cut?

KickAss Machines Inc.
Answer – The series of plasma units we offer have four different thickness cutting capabilities. In our experience, the ‘600’ is great for thin 24 ga. to 5/16” but we have on occasion, cut as thick as 1/2” plate at a low cut speed. Technique is paramount when it comes to penetration when pushing the thickness limits and you can expect to change out tips more frequently.

Can I use any torch?

Beadfx - Art Clay Silver - Frequently Asked Questions
Any torch that will bring the piece to the right temperature and hold it there is fine. I would tend to avoid using acetylene as it is sooty and could create a problem. Using a torch that is designed to be used in a horizonal position for 2 minutes is a good idea. Propane or MAPP torches with a swirl tip are an excellent choice, and are available from your hardware store.

How does it differ from conventional medicine?

Frequently asked questions
Conventional medicine sees the symptoms as a direct cause of the illness while Homeopathy sees the symptoms as the body’s reaction against the illness as it seeks to overcome it and therefore a homeopathic prescription will stimulate and not suppress this reaction.
