29 LEARNING T O WELD No one can learn to weld simply by reading about it. Skill comes only with practice. The following pages will help the inexperienced operator to understand welding and develop this skill. For more detailed information, order a copy of “ New Lessons in Arc Welding ” listed at the end of this manual. THE ARC-WELDING CIRCUIT T[...]

30 Fumes and slag generated from Innershield type electrodes recom- mended for use with this welding machine can be toxic. • Avoid contact with eyes and skin. • Do not take internally . • Keep out of reach of children. • Follow all safety precautions found in this operating manual. -----------------------------------------------------------[...]

31 The “ arc stream ” is seen in the middle of the picture. This is the electric arc created by the electric current flowing through the space between the end of the wire electrode and the base metal. The temperature of this arc is about 6000 ° F, which is more than enough to melt metal. The arc is very bright, as well as hot, and cannot be lo[...]

32 When comparing the GMA W and FCAW processes, you can see that the principal difference between the two lies in the type of shielding used. GMA W uses gas for shielding, thus we have Gas Metal Arc Welding. FCA W uses the melting or burning of the core ingredients for shielding, and is thus termed Self-Shielded Flux Cored Arc Welding. The recommen[...]

33 For FCA W (Innershield) Process 1. Do I want simplicity and portability? 2. Will welding be performed outdoors or under windy con- ditions? 3. Do I require good all position welding capability? 4. Will most welding be performed on 16 gauge and heav- ier , somewhat rusty or dirty materials? 5. Weld must be cleaned prior to painting. COMMON MET AL[...]

34 Butt Welds Place two plates side by side, leaving a space approximate- ly one half the thickness of the metal between them in order to get deeper penetration. Securely clamp or tack weld the plates at both ends, other- wise the heat will cause the plates to move apart. See Figure 17. Now weld the two plates together . Weld from left to right (if[...]

35 Fillet Welds When welding fillet welds, it is very important to hold the wire electrode at a 45 ° angle between the two sides or the metal will not distribute itself evenly . The gun nozzle is generally formed at an angle to facilitate this. See Figure 20. FIGURE 20 Welding In The V ertical Position Welding in the vertical position can be done [...]

36 FIGURE 21 V ertical-down Welding Refer to Figure 22 V ertical-down welds are applied at a fast pace. These welds are therefore shallow and narrow and, as such, are excellent for sheet metal. V ertical-down welds may be applied to 5/32 ” (3.9 mm) and lighter material. Use stringer beads and tip the gun in the direction of travel so the arc forc[...]

37 WELDING TECHNIQUES FOR THE SELF-SHIELDED FCA W PROCESS Four simple manipulations are of prime importance when welding. With complete mastery of the four , welding will be easy . They are as follows: 1. The Correct Welding Position Figure 23 illustrates the correct welding position for right handed people. (For left handed people, it is the oppo-[...]

38 3. The Correct Electrical Stickout (ESO) The electrical stickout (ESO) is the distance from the end of the contact tip to the end of the wire. (See Figure 24.) Once the arc has been established, maintaining the cor- rect ESO becomes extremely important. The ESO should be approximately 3/8 to 1/2 inch (10 to 12 mm) long. FIGURE 24 The easiest way[...]

39 Helpful Hints 1. For general welding, it is not necessary to weave the arc. Weld along at a steady pace. Y ou will find it easier . 2. When welding on thin plate, you will find that you will have to increase the welding speed, whereas when weld- ing on heavy plate, it is necessary to go more slowly in order to get good penetration. 3. When weldi[...]

40 4. After you strike the arc, practice the correct electrical stickout. Learn to distinguish it by its sound. 5. When you are sure that you can hold the correct electri- cal stickout, with a smooth “ crackling ” arc start moving. Look at the molten puddle constantly , and look at the “ ridge ” where the metal solidifies. 6. Run beads on a[...]

When using the GMA W process on light gauge material, weld from right to left (if you are right handed). This results in a colder weld and has less tendency for burn through. 2. The Correct Way T o Strike An Arc 1. Be sure the work clamp makes good electrical con- tact to the work. 2. Position gun over joint. End of wire may be lightly touching the[...]

42 4. The Correct Welding Speed The important thing to watch while welding is the puddle of molten metal right behind the arc. See Figure 30. Do not watch the arc itself. It is the appearance of the pud- dle and the ridge where the molten Puddle solidifies that indicates correct welding speed. The ridge should be approximately 3/8 ” (10 mm) behin[...]

43 Practice The best way of getting practice is to perform the following exercise. Refer to Figure 27. 1. Learn to strike an arc by positioning the gun over the joint and touching the wire to the work. 2. Position face shield to protect face and eyes. 3. Depress gun trigger, hold gun so contact tip to work dis- tance Is about 3/8 to 1/2 inch (10 to[...]
