Welding Stainless Steel

 

The DCH 2000 Gun

The DHC 2000 (formerly HENROB 2000™) has a unique mixing chamber inside the torch which creates a narrow concentrated heat & virtually oxygen free environment around the weld area. (see Home Page for moving diagrams) This enables the welding of normally difficult materials such as Aluminium, Stainless Steel, Chrome Moly, Cast Iron, Mild Steel etc., without the need for an inert gas shield or 3 phase power, such as is required for TIG & MIG Welding Equipment
It uses a neutral flame for most welding applications except stainless steel and hard facing of machinery blades where a carburising flame is used. (See Image 1 & 2)

 The low velocity flame with very little oxygen content protects the weld puddle in a similar way as TIG & MIG Welding Equipment, and therefore requires no flux on the majority of materials.


Aluminum requires a small amount of flux only on the rod as the gas shield of the torch has a deoxidising effect on the weld. However unlike a TIG where the work piece must be extremely clean around the weld area (usually achieved with a stainless wire brush) the DHC 2000 (formerly HENROB 2000™) requires little or no cleanup.

The torch has a long nozzle in comparison to TIG which enables it to reach into very hard to get at positions. It is very light and portable and is easily able to be used outside in windy conditions which makes it ideal for on-site work.

  

 

 

Undercuts

It is particular interest to note that DHC 2000 (formerly HENROB 2000™) produces no undercut along the weld seam as in the TIG/MIG process and therefore repair of a motor block, injection moulding etc, does not require machining on the plane side. This machining can be far more expensive that the actual welding.

Cutting and Brazing

Unlike MIG & TIG Welding Equipment the torch brazes & cuts.

 

All plate and sheet metal can be brazed without flux. Galvanised sheet metal can be cut and brazed without flux and without destroying the protective coating (essential in auto body repair work for applications where it is not possible to remove the flux residue), because of the non- oxidising flame even ordinary domestic copper wire can used as filler for brazing.

Clean, fast, economical cutting 

and is a feature of the DHC 2000

(formerly HENROB 2000™)

There are two cutting attachments, one for sheet metal and one for plate The torch produces a very narrow non-oxidised slag free clean cut up to 25MM and no machining is required before welding it. It is very fast and energy efficient giving huge gas savings compared to a conventional oxy cutter uses approximately half the gas.
