Bernzomatic is a company dedicated to combining heat and craftsmanship. Their products are useful for welders, as well as smaller heat-based crafting projects. If your work involves fire, then Bernzomatic is the way to go.
It depends on the product you're using. The products on Homelectrical's site use Map-Pro, Propane, and Butane, but some Bernzomatic products use oxygen cylinders.
