Light Line is a series of torches designed for small and light soft soldering and heating work. All torches have an M8 x 0.75 connection on the torch side and therefore fit both the neck tube 350101 and the cylinder valve 871601. The combination of the respective Light Line torch, the neck tube 3501 and the PRO 86 handle then results in a soldering set with hose connection, the assembly of the burner on the bottle valve 871601 in connection with the gas bottle 200026 results in a blowtorch. The possible combinations are diverse and enable individual adaptation to the respective application.
