WHY DO THE WELDERS BELOW PREFER THE DHC 2000?

Including comments from them, (shown as "quotations") which could assist you with your particular application.f

Very easy for students to use as it is very quiet and does not suffer from oxygen starvation as easily as a conventional oxy torch, therefore eliminating most of the "popping & banging", igniting and reigniting. The absence of these conditions makes the DHC 2000 a lot more user friendly especially with new students.

Saves around half the gas & filler rod costs.

Enables students to weld all metals, ferrous or nonferrous without the need for expensive MIG/TIG units.

I have included quotes from two Schools (full letters available upon request)

1) "From these students introduced to Dillon welding torches all found they were superior in flame heat control and were able to weld 2 mm Aluminium satisfactorily after 1 or 2 lessons of practice - approx. one to one and a half hours.
Through out this 2 month period of experimentation with 2 torches used by 18 students and two teachers, less than half a pair of size E cylinders of gas was consumed. Normally we replaced cylinders each month when 2 conventional torches are used"

2) "The Henrob is considerably easier for our unpracticed students to operate than the traditional Oxyacetylene torch as it is shorter and any hand waver is less pronounced at the point of flame.

The Dillon or Henrob 2000 as it is now known is just as happy with Oxy/LPG which we use for hard soldering students projects, and no matter whether ferrous or nonferrous material being joined we never had a problem"
(from Industrial Arts Teacher)

Minimal distortion with both welding and cutting panel steel due to its narrow concentrated flame. Ease of use due to only one pressure setting and one method of operation for all welding.

About twice the speed of a conventional oxy torch using about half the gas and filler wire.

Very little preparation and minimal grinding as welds lay very flat (does superb butt welding with no filler wire if there is no gap).

Brazes without flux which is very important if you are painting over the job as paint can lift if flux is not scrupulously cleaned off.

Huge range , from chassis repairs, cast iron manifolds right down to die cast door handles and the thinnest of panel steel, with a bit of practice it will even weld up aluminium or tin cans.

Advantages over MIG

No MIG splatter and a pliable weld which can easily be hammered, dollied and ground.

Can be used outside even in windy conditions without porosity, with no external power source.

Very little pre-cleaning required as the DHC 2000 will weld straight through rust & paint.

Very little grinding and finishing work due to welds laying very flat.

Very easy to use on thin Aluminium such as Landrover bodies and fuel tanks.

Can also cut, braze and has specialist tip (in kit) for soldering and the old art of lead wiping.

Note. Whilst a MIG appears to weld a lot faster, by the time you have cleaned the job thoroughly and done all the grinding and cleanup work necessary the DHC 2000 takes about the same time.

To quote from a professional car restorer (full letter available upon request)

"The job I brought it for turned out to be bigger than anyone expected, (how unusual,) with a huge amount of sheet metal patch repairs and complete panel replacement. As you can see in the photos, (Link to photos) going right across a guard to fit a new front half on is no problem, with very little warpage, compared to the old welding torch. In fact, I doubt I would have been able to do a lot of this work with the old equipment, as I ‘d be forever shrinking & hammering to keep things flat."

Another Australian Panel Beater & Hot Rod specialist likes the torch so much that he shows it on his web site (Link to web site).

To Quote him " I have been a specialist welder for many years with a conventional oxy torch & am well know all over Australia in the Hot Rod field. I recently came across a job which was virtually impossible to accomplish with my very extensive equipment. My mate had been pestering me for over a year to borrow his Henrob and I thought that this would be the ideal time to give it a trial. Well it did the job easily & when I changed back to my conventional torch it was like jumping out of a Formula 1 race car & climbing onto a horse & cart. I then contacted you to purchase my own unit"

Huge Gas Savings (Approx. 50%)

Easy to use.

No Flux required most of the time.

Much faster and easier on big diameter Copper Pipe (such as Fire Sprinkler Systems) where a normal oxy finds it very difficult to to get the heat in. Also much quicker on copper and Galvanized pipe where water keeps dripping due to leaky valves.

Does not burn off galvanized coating while brazing.
The ability to weld a wide range of materials on site, eg., Aluminium, Stainless Steel, Cast Iron, Cast Aluminium, etc., without the need for any external power source or the need for a shrouding gas shield.

Huge range, welds from thinnest materials to half inch thick steel, cuts up to 1 inch thick steel.

To quote from a plumber (full letter available on request) "Just a quick note to thank you for the speedy service in sending the new tip for my Henrob 2000. (Now renamed the DHC 2000) I hope you are not trying to make a living out of spare parts, as this is the only time I have had to replace anything in 12 years.

My torch is used everyday in my work as a plumber and despite years of use and sometimes abuse it has performed faultlessly. The No2 Tip I find excellent for silver soldering on pipes of all diameters. Other plumbers have been surprised that such a small torch and tip can join 100 mm copper tube".  

menu

Ability to weld materials on site even in the wind which would normally have to be sent to a specialist welder. Very easy to use compared to other welding equipment as only one pressure setting and one method of operation for all welding. Great on farm gates, welding and cutting stockyards, hard facing machinery blades, stainless steel on dairy farms, cast iron and all non ferrous repairs.

Very portable, due to minimal gas usage only the smallest gas bottles required.

Excellent for bending heavy steel and freeing up frozen studs without damaging the surrounding area due to the concentrated heat.

Halves gas cost. Cuts steel up to 25 mm thick (1inch) slag free and ready to weld like a plasma cutter.

Has a huge range, welds from aluminium or tin cans to 12.5mm(1/2inch) steel.

Has the ability to use what’s laying around as a filler rod e.g..., copper wire to repair even the thinnest rusty exhaust, cast iron piston ring or broken high speed twist drill to hard face implement blades or repair cast iron parts, fencing wire to repair steel.

To quote a customer of ours who is a farm maintenance contractor (Letter available upon request) "With a collection of filler rods its a go anywhere, weld anything torch, I wish I’d had one years ago".

And another quote "I have not done any welding yet, but have used the torch for cutting 3/4 inch (19 mm) steel. It slices through like a plasma cutter, giving neat fine cuts with nil finishing required".

Huge gas savings and minimal distortion on thin steel both welding and cutting.

Brazes without flux. Brazing galvanized does not burn off the coating.

Cuts up to 1 inch (25 mm) thick steel like a plasma cutter using less than half the gas of a conventional oxy torch in a much quicker time.

Cuts are ready to weld with virtually nil finishing work (e.g., No clean up with an angle grinder) and can be cut at a precise angle using the guide wheels.

Extremely portable and ideal for site work where external power and shrouding are difficult to achieve. Easy to use and set up.

Ability to weld all metals ferrous or non ferrous, such as Aluminum both cast and extruded, Stainless Steel, Cast Iron etc.

Bends steel very fast using about half the gas of a conventional oxy torch.

Huge range, welds from aluminium or tin cans up to 12.5mm(1/2inch) steel.

To quote a customer (letter available upon request) "Thin sheet metal and tube welds are far superior to a normal oxy torch with a much finer point of heat and very little distortion. In particular Aluminium welding is made simple with much greater puddle control, preventing the collapse you would normally get". (check out the video demonstration)

menu  

Strong as a TIG (see test results)

Approx. Half the distortion level of a TIG in thin Stainless Steel.

Pliable welds, unlike the brittle welds with MIG/TIG. So able to put through a roller without cracking.

Ease of use compared to MIG/TIG.

Minimal preparation of the job.

Very little grinding and finishing work.

Very little Carbon Precipitation on other side of weld. (note. Pipes in food industry are purged the same as for TIG).

Huge Welding Range, from Aluminium cans to 12.5mm (half inch) thick steel.

Cutting from tin cans to 25 mm (1inch) Steel like a plasma cutter. Note. Does not cut Non Ferrous materials.

To quote from a stainless steel welder (letter available on request) "G’day Barry & Lynn, The Henrob hand piece is working brilliantly on stainless steel ballustrading I’m doing currently. But welding 40mm tube to 3mm end plates, welding bases on 25mm x 5mm staunchions and making up fiddly wall anchor brackets. I’ve been welding stuff in place on the balcony in the wind and rain no probs. Great product!" Regards Wayne.

menu

Strong as TIG (see test results)

Ease of use compared to MIG/TIG especially on thin Aluminium.

Minimal clean up of the job as lays a very flat weld bead.
Much easier to build up the filler rod to replace broken parts eg.., broken lug. Superb with Cast Aluminium and Die cast.
Very pliable welds, especially important if subjected to excessive vibration where MIG/TIG welders tend to crack due to metal fatigue. Heavily used by the Racing Fraternity for this reason.

Able to be used out in the wind, even on dirty Aluminium, ideal for on site work.

(Note. Although the torch will weld through dirt, paint, oil and rust, we point out that if the material is oil impregnated or salt water encrusted then these materials need to be thoroughly cleaned).

Huge welding range, from Aluminium cans to Engine Heads. (Although on a larger mass preheating is required the same as should be done with TIG. Approx. 300 deg. C. )

To Quote a customer (letter available on request) "I just wanted to let you know how happy I am with my purchase and how impressed I am by the abilities of the Henrob Torch (DHC 2000). I am quite a reasonable TIG Welder having been welding motorcycle and push bike frames for myself for a few years, but have never tried gas welding previously. After the initial set up which was very easy using the included instructions, I was up and welding within a few minutes and am blown away by the quality of the welds! I did not know what to expect before I started but can safely say that the quality of finish from this torch exceeds that of my TIG Welder, even after about an hours practice!

I am especially impressed by the control I have over the weld puddle. I was expecting to blow holes in the material and even tried to in some cases, and yet the puddle just followed the torch and never burst through. The much more localized heat from the torch is also obvious as I was welding a painted frame and the paint only burned of in a very small area, whereas the TIG tends to strip a very large area around the weld"

Another Quote from a Motorcycle Speedway Racer (Letter also available) "Look no Bullshit, its the best thing for welding Aluminium fuel tanks up at work or at the track, any welding repairs on my outfits. Look you would not believe how fine a weld you can do with it, I made a dummy fuel tank out of beer cans as a joke for another rider I welded them together. As you should know you cannot use a TIG, MIG or Stick Welder without power, and for TIG and MIG they are bloody hopeless if you are not in a shed or if there is any wind"

Finally a quote from a South Australian Welder/Axeman who sent us a great photo of an Aluminium Axes Box he made using the torch "Just a short note to let you know how my Henrob Torch is going. I am very pleased with its performance and I have never seen anything so versatile. I have welded Aluminium, Cast, Steel, Copper, Stainless Steel. The hardest was probably the Aluminium, it took me a couple of hours just playing to get the hang of it, now I can run a weld along a piece of 0.6mm for as long as I want"

TIG strength welds in materials such as Chrome Moly, Aluminium, Magnesium, Stainless Steel, Mild Steel, Cast Iron, etc.,

Ease of use for the average person.

Minimal Distortion of welds.

Pliability of the welds. (Unlike MIG/TIG where the brittle weld can be subject to metal fatigue especially in areas with heavy vibration) The DHC 2000 welds are as pliable as the surrounding material and can for example be put through a roller.

One of our customers was having the Chrome Moly supports of his speedway car TIG’D nearly every month as they kept re-cracking due to excessive shaking and movement. He purchased the DHC 2000 and contacted nearly 7 years later to tell us that the weld was still intact. This feature is especially important for all Aircraft welding.

The ability to use anywhere, even right at the Racetrack in the wind and rain. This is a massive advantage as repairs can be done track side, which would normally prevent racing, sometimes for weeks.
 
menu

Ability to weld even the thinnest of Aluminium, Steel, Copper, Brass or Stainless Steel with minimal distortion and a pliable weld without the blow out you would normally get with most other welding techniques.

Very controlled Silver Soldering and Brazing especially in tight places where heat spread is a major problem.

Ability to use on site even in the wind, without external power source or shrouding.

We phoned a customer in Melbourne who repairs Heat Exchangers and asked him if he would give us a quote for this web site and he refused. He told us that he had become the leader in his field of repairing these units, as a lot of his work would normally be found irreparable and thrown away , no one else could do it and he didn't want everyone knowing that he used the DHC 2000 because the competition would then buy one and he would lose his edge.

We will just quote from a letter from an Antique Bed Restorer. (Letter available on request).

"I have been using the Henrob (DHC 2000) for the last 4 years with fantastic results. When restoring old Cast Iron Beds, especially intricate fancy Cast Iron designs, the Henrob allows me to flow the Cast Iron freely and with ease using old piston rings. I can repair old Brass fittings belonging to the bed which can be extremely thin. The Henrob allows me to weld even the thinnest of materials"

menu

 
A leading company who manufacture delicate glass instruments for forensic applications have had a number of DHC 2000 for the past 15 years with virtually nil servicing and have been very happy with them.

They find the DHC 2000 torch superb for joining delicate glass equipment as the narrow concentrated heat and low velocity make a small neat join unlike the fat ugly one that they encountered previously using conventional equipment.
 
menu

 
Jointing of even the smallest diameter cables with minimal heat spread and damage to the insulation.
To quote a customer (Letter available upon request) "Since the purchase of your Henrob welding hand piece we are please to report out productivity and quality of finished work have increased by 200% and 300% respectively.

The uses of fluxes and gas has also been remarkably decreased. Our main use for the tool is the butt welding, with silver solder, of tinned copper wires as small as 0.4mm.

We take this opportunity of recommending the use of this tool to anyone wishing to streamline efficiency, performance and cost"

I have included quotes from two separate Sculptor/Artists (Both letters available upon request).

"The torch has opened several new avenues for me to explore in my work with the simple and efficient way you can weld stainless steel, aluminium and in fact most metals that in the past I have found extremely difficult with my limited knowledge of welding.

Since using the Henrob I have found that I can produce up to 6 works from an equivalent amount of gas that in the past with another named brand welding torch I was only able to produce one and a half to two pieces of sculpture of similar size"

Second Quote "We create murals and signs using the Henrob Torch. The fine Cutting we do would not be possible without this torch and also the reduction in gas use is remarkable, with any other torch we make One Harley Mural with the Henrob we can produce Seven"

So as you can see this is a very versatile piece of equipment which is easy to use and opens up whole new possibilities for artists and sculptures.

The ability to weld even very thin Cast Aluminium or Magnesium Mower bodies to TIG strength, even when dirty (see video??? Link).

To quote a customer (letter available upon request) "One problem has always been repairs to cast alloy chassis and other mower alloy componentry which is almost impossible with normal Oxyacetylene welding equipment. Your product has filled a great need in this area"

Note. This customer at the time he wrote the letter was the National Chairman of the Mower Serviceman's Assn. of Australia.

menu  

TIG strength repairs in Aluminium, Stainless Steel, Steel boats, etc.

Superb with propellor build ups of any material.

Can be used right on site even in the wind. E.g., in Australia we sell it to Fisherman in remote Northern Territory locations, where they find it very difficult to access electricity. They do all their welding even on the beach, which they would normally had to send away to specialist welders.

menu

Tremendous control on delicate fine metals of any type, ferrous or nonferrous.

Low flame velocity & lack of turbulence prevents the weld puddle from blowing out.

Narrow intense concentrated heat enables pin point welding with minimal damage to surrounding materials.

Note. We demonstrated the torch to a model makers club of about 45 members and sold nearly everyone a kit. (As we recall they made model trains and steam engines)
