A Craftsman 20 70-amp arc welder is a piece of equipment designed for arc welding, a process that uses an electric arc to melt and fuse metals together. Specifically, this type of welder is likely a stick welder, also known as shielded metal arc welding (SMAW), which uses a consumable electrode coated with a flux to protect the weld puddle. It's capable of welding up to 1/8-inch thick metal, and with layered welding, can handle most metal thicknesses. Here's a more detailed breakdown: Arc Welding: This process uses an electric arc, a high-energy stream of electricity, to create intense heat (up to 6,500°F) that melts the metal at the joint. Stick Welding (SMAW): In this type of arc welding, a coated electrode is used, and the flux coating protects the molten metal from atmospheric contamination. 70 Amps: This indicates the maximum amperage output of the welder, which influences the thickness and type of metal that can be welded. 20: This likely refers to the model number or series within the Craftsman line. Capabilities: The welder can typically handle 1/8-inch thick metal and, with layered welding techniques, can weld thicker metals.
