steel can usually be easily welded without special pre- cautions. Some steels, however, contain higher car- bon levels or other alloys and are more difficult to weld. Basically, if a magnet sticks to the metal and if you can easily cut the metal with a file, chances are good that you will be able to weld the material with the SP-100. For further information on identifying various types of steels and other metals, and for proper proce- dures for welding them, we again suggest you pur- Penetratio
