    EZITIG 205DC process including greater weld penetration for less work heat input and greater control of the weld pool. The basic theory for setting the base current using pulse mode is that the base current should be sufficient to maintain the existing molten weld pool, while the peak current is sufficient to melt new metal in order to move/ expand the molten weld pool.

    EZITIG 205DC 3.3.3 MMA Welding One of the most common types of arc welding is manual metal arc welding (MMA) or stick welding. An electric current is used to strike an arc between the base material and a consumable electrode rod or ‘stick’. The electrode rod is made of a material that is compatible with the base...
  • Page 20: Mma Welding Fundamentals

    EZITIG 205DC Manual metal arc ( stick) electrodes have a solid metal wire core and a flux coating. These electrodes are identified by the wire diameter and by a series of letters and numbers. The letters and numbers identify the metal alloy and the intended use of the electrode.
  • Page 21 EZITIG 205DC  Electrode Size The size of the electrode generally depends on AverageThickness Maximum Recommended the thickness of the section being welded, and of Material Electrode Diameter the thicker the section the larger the electrode 1.0-2.0 mm 2.5 mm required.
  • Page 22: Mma Welding Trouble Shooting

    EZITIG 205DC  Electrode Angle The angle that the electrode makes with the work is important to ensure a smooth, even transfer of metal. When welding in down hand, fillet, horizontal or overhead the angle of the electrode is generally between 5and 15 degrees towards the direction of travel. When vertical up welding the angle of the electrode should be between 80 and 90 degrees to the work piece.

  • Page 33 EZITIG 205DC Electrode Tip/Flat The shape of the tungsten electrode tip is an important process variable in precision arc welding. A good selection of tip/flat size will balance the need for several advantages. The bigger the flat, the more likely arc wander will occur and the more difficult it will be to arc start. However, increasing the flat to the maximum level that still allows arc start and eliminates arc wonder will improve the weld penetration and increase the electrode life.
