Product Details It is ideal for general soldering jobs, heating applications and general jewellery making tasks. This product is for use with Sievert torches and torch kits only. It is advisable to switch off at the gas bottle before the torch handle. This allows all the gas to burn from the tube and burner and prevents malfunction, usually caused by a build up of crystallized gas in the burner, blocking the jets. Other sizes are available.
