  • Page 22 Operators Manual 3. Stick welding skill 3.1 Welding Positions There are two basic positions, for welding: Flat and Horizontal. Flat welding is generally easier, faster, and allows for better penetration. If possible, the work piece should be positioned so that the bead will run on a flat surface. 3.2 Preparing the Joint Before welding, the surface of work piece needs to be free of dirt, rust, scale, oil or paint or it will create brittle and porous welds.

  • Page 26 Operators Manual 2.3 Types of Weld Bead The following paragraphs discuss the most commonly used arc welding beads. The stringer bead Formed by traveling with the electrode in a straight line while keeping the electrode centered over the weld joint. The weave bead Used when you want to deposit metal over a wider space than would be possible with a stringer bead.
  • Page 27 The first attempts in practice will probably fall short of acceptable weld beads. Too long of an arc will be held or the travel speed will vary from slow to fast (see following) Model No MOMACDC...
  • Page 28 Operators Manual A. Weld speed is too fast B. Weld speed is too slow C. Arc is too long D. Ideal weld A solid weld bead requires that the electrode be moved slowly and steadily along the weld seam. Moving the electrode rapidly or erratically will prevent proper fusion or create a lumpy, uneven bead.
