What “1/2-inch capacity” really means For a fabrication shop, a cutter that can sever 1/2-inch steel is not necessarily a cutter that will make clean, production-ready cuts through it all…
A portable stick welder is often the most practical machine for repairs away from a workshop. It tolerates dirty steel better than MIG, does not require a shielding-gas bottle, and…
