Cutting Thick Steel

Cutting Thick Steel with the HENROB 2000 oxyacetylene torch

Cutting Thick Steel with the Henrob 2000

Cuts up to 1" thick steel

We use the copper and #2 tips.

The copper tip (oxygen) should be between 1/16" and 1/8" up off of the metal. Watch the oxygen tip, and not the flame

Increase the oxygen pressure (see below) and leave the acetelyene at 4 PSI

• 1/4" - 8 to 10 PSI
• 1/2" - 15 PSI
• 1" - 21 to 25 PSI

start at the far side, heat metal red, pull trigger and slowly draw torch across metal

NOTE: Metal needs to be red only when STARTING cut

Travel speed faster than conventional torch.

remember to keep the tip close 1/16" to 1/8" - Closer is better

General

• The maximum thickness of steel you should attempt is 1" Thicker metals will require preheating.

• attach the over cutter
• use the #2 on the weld point
• use the copper tip on the cutting attachment- see diagram above

• use 4 to 4 1/2 psi on acetelyene and

• adjust oxygen pressue depending on thickness of metal:

  • 1/4" - 8 to 10 PSI
  • 1/2" - 15 PSI
  • 1" - 21 to 25 PSI
• if a 50' hose is used, increase your pressure 1 to 2 psi (see setting up the torch)

• Use a neutral or just off feather with trigger depressed
• See setting up torch

• When cutting thick steel - always preheat
• Start at the far side, heat metal red, pull trigger and slowly draw torch across surface
• Surface needs to be red only when STARTING cut.
