I ran my welder at about 350 amps if memory serves me right and it cut through the side of a stamping press about 4-5" thick. A thermal lance, thermic lance, oxygen lance, or burning bar is a tool that heats and melts steel in the presence of pressurized oxygen to create very high temperatures for cutting. It consists of a long steel tube packed with alloy steel rods, which serve as fuel; these are sometimes mixed with aluminum rods to increase … Ver mais One end of the tube is placed in a holder and oxygen is fed through the tube.
