    Firepower MST 180i 4.02 MIG (GMAW/FCAW) Welding Troubleshooting Solving Problems Beyond the Welding Terminals The general approach to fix Gas Metal Arc Welding (GMAW) problems is to start at the wire spool then work through to the MIG Gun. There are two main areas where problems occur with MIG, Porosity and Inconsistent wire feed Solving Problems Beyond the Welding Terminals - Porosity When there is a gas problem the result is usually porosity within the weld metal.

  • Page 68 Firepower MST 180i Distortion Distortion in some degree is present in all forms of welding. In many cases it is so small that it is barely perceptible, but in other cases allowance has to be made before welding commences for the distortion that will subsequently occur. The study of distortion is so complex that only a brief outline can be attempted hear.
  • Page 69 Firepower MST 180i D. Presetting It is possible in some cases to tell from past experience or to find by trial and error (or less frequently, to calculate) how much distortion will take place in a given welded structure. By correct pre-setting of the components to be welded, constructional stresses can be made to pull the parts into correct alignment.
