There are two reasons for using a fuse.
First, because of the extremely high temperatures involved, you will need time to get to a safe distance before the reaction starts. Second, thermite has a very high ignition temperature, so an ordinary flame usually can't set it off.
Thermite welding is all about using thermite for welding steel or iron. Thermite is actually a mixture of iron oxide and powdered aluminum.
For the classical iron oxide and aluminum thermite, the products of the reaction are aluminum oxide (Al2O3) and iron (Fe). However, there are many kinds of thermite, but they always produce the pure metal from the oxide.
Thermite is not an explosive. However, most types of thermite, especially copper, burns very hot and fast, and can splatter molten metal all over the place. It doesn't go boom like a pack of TNT, but it is still pretty dangerous.

The person that is credited with inventing thermite is German chemist Hans Goldschmidt. He created it in 1893 using ion oxide and aluminum metal granules.
Thermite welding is all about using thermite for welding steel or iron. Thermite is actually a mixture of iron oxide and powdered aluminum.
Copper thermite is a type of thermite where instead of the iron oxide, copper oxide is used instead. The reaction produces pure copper metal, but this thermite gets a little more splattery than the iron thermite.
Thermite is manufactured from pure metals and avoiding the use of carbon in the process of it. Thermite was originally discovered by a German chemist named Hans Goldschmidt.
A welding torch might work. But it's not always very safe, since you are standing rather close to the thermite if you are torching it directly. If you can't get your hands on magnesium, you can try to use some types of sparkler fuses. Some of these fuses are hot enough to initiate thermite, although I'll just go with magnesium to save the hassle if a fuse doesn't work.
Thermite reaction is used in industry for welding steel together in-place
Thermite is not illegal in (most) countries, as long as you keep yourself and everyone else safe from it.
Sounds like it could be the ECM fuse. You need to have someone check it for a short.
Thermite is a mixture of 1 part aluminum oxide for every 3 parts iron oxide
For the classical iron oxide and aluminum thermite, the products of the reaction are aluminum oxide (Al2O3) and iron (Fe). However, there are many kinds of thermite, but they always produce the pure metal from the oxide.
Thermite has its own oxygen source so it can burn without an outer source of oxygen, including underwater and in the vacuum of space. However, I do doubt that thermite can burn in space, since space is quite cold. It would just depend in how far away from the Sun you are when you light the thermite.
