Sievert Blowtorch without gas cartridge

Butajet soldering torches and soldering irons are small and lightweight soldering devices. All can be operated with regular butane (lighter gas) and are easy to refill. They are particularly suitable for small and delicate soldering tasks and are, of course, significantly less powerful than, for example, Powerjet or Handyjet soldering torches. However, they are excellent for work in model building and electronics.
