A SYNOPSIS OF TEST RESULTS ON THE DHC 2000 (formerly HENROB 2000™)
By (amongst others) Swiss Welding ASSN. Swiss Federal Institute of Technology, European Nuclear Research Centre Geneva.
(Mechanical Resistance Tests Performed with Instron Equipment) The following features and advantages were found.
- High Mechanical Resistance of the weld joint (Aluminum and Stainless Steel equivalent to T.I.G.)
- Important reductions in pre and post welding operations including grinding, planing, cleaning.
- 50% reduction in filler rod consumption (smaller weld bead than conventional oxy torch)
- Savings in gas 54% Acetylene, 61% Oxygen using recommended tips 0 & No.1.
On Tensile tests on fusion welded butt joints on Aluminium and Stainless Steel the following results were produced according to Din 50 120 standards.
Sample used 1.5MM
Aluminium force applied 1000KG.
Breaking force
T.I.G Sample 400KG
DHC 2000 (formerly HENROB 2000™) Sample 420 KG
Sample used 304L Stainless Steel 2MM,
forced applied 2000KG
Breaking force
T.I.G Sample 1900KG
DHC 2000 (formerly HENROB 2000™) Sample 2000KG
Both the TIG and DHC 2000 welds broke near the joint.
All joints resisted the test.
Inter Crystalline corrosion resistance (Stainless Steel) No traces of cracks were observed during the tests with DIN 50 - 914 standards.
Complete test results available on request.

Bench Test
Bench Test on DHC 2000 - carried out by Mt. Druit TAFE in NSW

THE DHC 2000 has been developed over a period of 11 years. To obtain optimum performance of the unit the instructions should be understood and followed with reasonable accuracy. There is a set-up procedure for the torch in order for it to operate correctly. This set-up procedure is outlined in the instruction manual and it is demonstrated on the DVD video supplied. Once the instructions are understood, it only takes a few minutes to set the machine up. The DHC 2000 can be connected to conventional regulators. The torch uses equal quantities of oxygen and acetylene. Both regulators are set at 4 P.S.I or 28 KPA, which means it is very economical on gas usage..... read more...
