Exothermic cutting is a chemical reaction
(oxidation) that occurs when a steel tube filled with alloy wire
is heated to its kindling temperature and injected with pure oxygen.
The result is a consumable cutting torch that burns at a temperature
of 7200 to 7400 degrees. Exothermic cutting is extremely efficient
for rapidly cutting ferrous and non ferrous materials.
Standard Burning Bars
There are a number of generic terms used to describe
exothermic cutting torches commonly called Burning Bars, they
are also referred to as Lance Bars, Lance Rods, Mag Bars, Mag
Rods, Burning Lances, Exothermic Torches, Thermic Torches and
Thermic Lances. Oxylance manufactures a wide variety of diameters
and lengths from the .408” od to our largest burning bar at 1.05”
od. Lengths available are 5’3”, 7’, and 10’6”.
Burning Bar Holders
Burning Bars require a special holder to attach
the burning bar to the oxygen source. The Lever Action holder
is designed to grip the burning bar to hold it in the holder and
at the same time seal the burning bar to prevent oxygen leaks.
Oxygen Hose
Oxylance offers a variety of oxygen hose and fittings.
The most important aspect of the oxygen hose is to use a hose
large enough that it will not restrict the flow of oxygen to the
burning bar.
Oxygen Regulators
A high volume oxygen regulator is a must for efficient cutting
with burning bars. The regulator also needs a large enough port
that when used with ½” or ¾” hose it will not restrict the flow
of oxygen.
