Notes, Cautions and Warnings Keep all fumes and gases from the breathing area. A welding power supply is a device that provides an electric current to perform welding. Welding usually requires high current over 80 amperes and it can need above. The WeldHelp Resistance Welding Troubleshooting Guide is written for operators and engineers to help diagnose and solve common spot welding defects and issues. Download international and US standards from the full collections of ISO and IEC standards, American National Standards and thousands of regional and foreign standards. Throughout this manual, notes, cautions, and warnings Keep your head out of the welding fume plume. Wear dry gloves and clothing. Insulate yourself from the work piece or other parts of the welding PLASMA ARC RAYS circuit. Repair or replace all worn or damaged parts. Plasma Arc Rays can injure your eyes and burn your skin.
