History of the DHC2000
(Formerly known as The Dillon, The
Dillon MKIV, Henrob 2000, Cobra
torch)
Dillon
In the early 1970's near Adelaide, Australia a man named Ed Dillon
(a coppersmith), set out to develop a torch that would save gas,
Oxygen & Acetylene to be exact, as he lived many miles from
a supplier to refill his tanks.
After 11 years of development, he discovered many other things
about the characteristics of the 2 gasses and found the unique
mixing chamber with equal pressures and volume changed the flame
composition to make it burn around 600 deg.F hotter, cleaner (less
oxidation of the weld puddle, with 80% less flame pressure and
of course with less gas consumption.
In the early 1980's the torch was introduced to the USA and hundreds
were sold, at that time it was made in Switzerland under the Dillon
name.
Dillon MKIV
It was also sold as the Dillon MKIII or MKIV The only difference
was basically the handles some were smooth, some were black and
some were even plastic, the torch still uses the original design
today so replacement parts will fit the older torches with the
only variable being some of the older torches have the European
hose fittings, we have seen those sold on e-bay and there are
NO ADAPTERS available to make them fit US hoses, (B Fittings)
these are the standard US fitting, those are on the current torches.
There were some counterfeit torches made under the Dillon Industries
name these have no serial # and are not warranted, however the
parts are still interchangeable.
Henrob 2000
The Henrob Corporation started making the torch in the USA around
1985 and started calling it the Henrob 2000 to promote their name
and riveting system which is used on the heat shield included
in the torch kit and many OEM vehicles and is now Henrob's main
business.
Cobra Torch
Cobra torches purchased the torch division in 2002 the new name
was introduced in April 2005 as the DHC 2000 (Dillon, Henrob,
Cobra) The company recognized the importance of the previous names
and included them in the new name. Today the torch is still hand
made in the USA in Rochester, MI By Cobratorches, Inc.
