Before starting to weld, you need to light up the welding torch if you are using oxyacetylene welding torches. These are usually spark torches. When you place it in front of the torch and turn it on, it creates a spark which causes the torch to fire up and start. These are also known as spark lighters because of how they work. We have a range of lighters in different sizes and powers to be used for welding torches. Use these and weld different products like jewelry, metals, aluminum, alloys etc.
