MIG Welding When there is a gas problem the result is usually porosity within the weld metal. Porosity always Troubleshooting stems from some contaminant within the molten weld pool which is in the process of escaping during solidification of the molten metal. The general approach to fix Gas Metal Arc Welding (GMAW) problems is to start at the wire spool then Contaminants range from no gas around the... - Page 17 Wire feeding problems can be reduced by checking the following points.

Small (Fig 1-12) welding machines will only provide current (amperage) to run smaller sized electrodes. - Page 19 brittleness, generally cracks when attempts are between the pieces being joined to ensure proper made to weld it. Trouble may also be experienced penetration of the weld metal and to produce when welding white-heart malleable, due to the sound joints.

Page 25: Tig Basic Welding Guide
TIG Basic Welding Guide TIG Welding is a fusion procedure that uses an electric ARC created between an infusible tungsten electrode and base material to be welded. For TIG welding an inert gas must be used (Argon) which protects the welding bead. If filling material is used, it is made up of rods suitable to the material to be welded (steel, stainless steel, copper etc). - Page 26 (Fig 16-3) ARC Welder Point Grinding Wheel Radial Ground Wrong Tungsten Preparation - Wandering ARC Diameter of the flat determines amperage capacity.
