    The basic level of troubleshooting is that which can be performed without special equipment or knowledge, and without removing the covers from the Power Supply. If major components are faulty, then the Power Supply should be returned to an Accredited Thermal Arc Service Agent for repair.

  • Page 56: Solving Problems Beyond The Welding Terminals

    FABRICATOR 210 6.02 Solving Problems Beyond the Welding Terminals The general approach to fix GMAW/FCAW problems is to start at the wire spool then work through to the MIG torch. There are two main areas where problems occur: Porosity When there is a gas problem the result is usually porosity within the weld metal. Porosity always stems from some contaminant within the molten weld pool which is in the process of escaping during solidification of the molten metal.
