  • Page 54 FIREPOWER TIG 140 AC/DC BASIC WELDING Metal Being Joined Electrode Comments Mild Steel E6011 This electrode is used for all-position welding or for welding on rusty, dirty, less-than-new metal. It has a deep, penetrating arc and is often the first choice for repair or maintenance work.
  • Page 55 BASIC WELDING FIREPOWER TIG 140 AC/DC Art # A-07694 Figure 4-8: Overhead Position, Fillet Weld Joint Preparations In many cases, it will be possible to weld steel sections without any special preparation. For heavier sections and for repair work on castings, etc., it will be necessary to cut or grind an angle between the pieces being joined to ensure proper penetration of the weld metal and to produce sound joints.
  • Page 56 FIREPOWER TIG 140 AC/DC BASIC WELDING Arc Welding Technique - A Word to Beginners For those who have not yet done any welding, the simplest way to commence is to run beads on a piece of scrap plate. Use mild steel plate about 1/4" (6.0mm) thick and a 1/8" (3.2mm) electrode. Clean any paint, loose scale or grease off the plate and set it firmly on the work bench so that welding can be carried out in the downhand position.

Butt Welds Set up two plates with their edges parallel, as shown in Figure 4-11, allowing 1/16" (1.6mm) to 3/32" (2.4mm) gap between them and tack weld at both ends.
