After the pressure reducers, the valves and the tubes we could not speak of the torches.
First it is necessary to distinguish the purpose of the work to be performed.
It seems trivial but sometimes it is not clear that there are cutting torches, from balance-brazing and heating. For the moment we focus on these three types that are the most widespread ones.
After defining the use it is essential to understand what type of combustion gas we have to use. Normally oxygen can be used in combination with acetylene or oxygen in combination with methane or propane and its mixtures.
This is especially important since improper use is potentially dangerous.
Let's examine the cutting torch that is the most widespread.
There are cutting torches that are composed of grip and lance and monoblock cutting torches. Both have the possibility of being operated with a lever or with flyer.
The choice is very personal and depends on various factors including the habit, cutting position and the length of the torch.
The so-called demolition torches are torches that have a minimum length of 500 mm with 90 ° or higher head up to 180 ° (straight toe).
Normally these have a tip mixing, ie the combination of the gases takes place directly in the cutting tip. The advantage is that the same torch can mount both acetylene and propane / methane tips.
The torches that have gas mixing in the handle instead are specific and must be used only with the tips to which they are in charge.
The distinction of the tips ranks according to the maximum cutting thickness.
The brazing lances are also distinct from the type of use gas and the flow rate in LT / H which determines the calorific capacity.
An almost separate sector is the heated lance, also to be defined according to the type of fuel gas and in relation to the surface to be heated.
This is normally used for the preparation of sheet metal to weld or to dip components that must be disassembled, such as joints, bolts, bearings etc.
We always recommend that you check the compatibility of the components that form a torque setup both for the purposes of safety and a correct use.
