    My bet is oxy-acetylene...

    not oxy-acetylene. with the cutting tip that close to the work piece most likely oxy- map gas of even natural gas Too many flames for act either most will only have a max of six 4 for thinner and as few as two for cutting real thin in straight line or slicing rivets
    Never try to tell me it can't be done
    When I have to paint I use KBS products

    From: The FABRICATOR (an industry magazine for the metal fabrication trades)
    "For material 3 in. and thicker, the answer is usually pretty straightforward. Typical laser cutting operations handle material up to about 1 to 1.25 in. thick. Plasma cutting’s upper limit is between 2 and 3 in. For extreme thicknesses of steel plate—4, 6, 8, and even 10 in.—oxyfuel cutting is truly at home."

    Flames coming out of the tip were my give away. LASER cutting can be up to 150mm or about 6 inches. But the Kerf is Tiny. Power input for such a LASER is roughly 7 times the LASER rating. So we are talking enough for a couple thousand homes when cutting that thickness of metal. And LASERS use an Oxygen stream too.

    Pretty nice cut. I agree with Frank that it's Natural Gas. For the quantities that you would be pouring into such a process natural gas makes the most sense. Imagine the Gas and Oxygen bills for that place!

    I am trying to imagine the cost for that hunk of steel.

    It seems there would be much more cost effective ways to make letter. Unless that “D” is just shown for a visual effect?

    Plate steel right now is running from 1 to 3 dollars per pound depending on thickness quantity and supplier

    Recently I bought a 4ft by 4 ft 2" plate 80 lbs per ft 16 total sq feet cost me $1,600.00
    That plater being cut is about 4 inches thats 160 lbs per sq ft not cheap

    I have been enlightened. The term I was looking for is Oxyfuel. Thank you Frank...
