BROCO - HOT SHOT Kit

(Pressure regulator and oxygen bottle are not included in the set)

Functioning:

The following articles and accessories are required to work with Hot-Shot thermic lances:

• Art-No 60300 - Hot-Shot Kit
• Battery with min. 12 volt and 10 Ah. A battery for motorbikes with these characteristics is sufficient.
• Oxygen bottle (the size depends on the quantity of material you want to cut and existing means of transport /space.
• Pressure regulator for oxygen
• Appropriate quantity of thermic cutting rods for the planned application

Connect the pressure regulator to the oxygen bottle and the end of the oxygen hose to the exit of the pressure reducer. The clamps of the strike plate and the handle of the tool are connected to the battery according to the colour code (red to +, blue to -). Select the appropriate cutting rod and collet depending on the object you want to cut. Unscrew the nut of the handle in order to place the collet then tighten the nut slightly. Now place the thermic rod in the collet (the hollow end of the rod must be placed in the collet/handle) and tighten the nut completely. Now open the valve of the oxygen bottle and adjust the level of oxygen pressure using the pressure reducer. Now touch the strike plate with the tip of the thermic rod in order to create short circuit sparks. Push the mechanism of the handle, in order to let the oxygen flow through the cutting rod and thus igniting the rod. It is possible to adjust the oxygen pressure again in order to start cutting. The higher the oxygen pressure /throughput, the higher the temperature at the tip of the rod. While higher temperature allows faster cutting it will also result in a faster burning of the thermic rod. In order to cut, place the tip of of the rod directly on the surface of the object you want to cut.

When selecting the thermic cutting rods to be used keep in mind that the diameter of the rod and the length of the rod, in combination with the oxygen pressure used, influence the speed of the cut. The oxygen pressure that is optimal depends on the material that is to be cut. The producer recommends the following approximate oxygen pressures for different types of metals:

0.6 - 1.4 bar for the punc  turing hard metal plates

1.5 - 3.0 bar for the cutting of steel plates up to 0.7 mm thickness

3.0 - 3.5 bar for the cutting of steel plates up to 15 mm thickness

3.5 - 4.2 for the cutting of steel plates from 15 mm to 50 mm thickness

4.2 - 5.5 for the cutting of steel plates over 50 mm thickness

Unfortunately the producer does not give recommendations for the cutting of concrete, bullet proof glass or other materials. Users can quickly find out the optimal oxygen pressure through some short testing, though.
