Stick welding is probably the most familiar welding process known. A coated ELECTRODE, the weld rod, is clamped into an ELECTRODE HOLDER, an insulat- ed clamping device, which in turn connects to the ELECTRODE CABLE, a heavy wire. The WORK, the metal piece to be welded, is connected to the WORK CABLE, a heavy wire which contains the WORK CLAMP. Qua[...]

B-9 OPERA TION B-9 BULLDOG™ 140 No one can learn to weld simply by reading about it. Skill comes only with practice. The following pages will help the inexperienced welder understand welding and develop his skill. For more detail ed information, order a copy of the book “New Lessons in Arc Welding.” (See Book Division section at rear of manua[...]

B-10 OPERA TION B-10 BULLDOG™ 140 The function of the covered electrode is much more than simply to carry current to the arc. The electrode is composed of a core metal wire around which has been extruded and baked a chemical covering. The core wire melts into the arc and tiny droplets of molten metal shoot across the arc into the molten pool. The[...]

B-1 1 OPERA TION B-1 1 BULLDOG™ 140 PRACTICE The best way of getting practice in the four skills that enable you to maintain: 1. Correct Welding Position. 2. Correct Way to Strike An Arc. 3. Correct Arc Length. 4. Correct Welding Speed. is to spend a little more time on the following exercise. Use the following: Mild Steel Plate: 3/16” (4.8mm),[...]

B-12 OPERA TION B-12 BULLDOG™ 140 Now weld the two plates together. Weld from left to right (if right-handed). Point the electrode down in he gap between the two plates, keeping the electrodes slightly tilted in the direction of travel. Watch the molten metal to be sure it distributes itself evenly on both edges and in between the plates. Penetra[...]

B-13 OPERA TION B-13 BULLDOG™ 140 Vertical-Up Welding The problem, when welding vertical-up, is to put the molten metal where it is wanted and make it stay there. If too much molten metal is deposited, gravity will pull it downwards and make it “drip”. Therefore, a certain technique has to be followed: 1. Use 1/8” (3.2mm) 90-115 amps or 3/3[...]

B-14 OPERA TION B-14 BULLDOG™ 140 Overhead Welding Various techniques are used for overhead welding. However, in the interest of simplicity for the inexperi- enced welder, the following technique wil l probably take care of his needs for overhead welding: 1. Use 1/8” (3.2mm) 90-105 A or 3/32” (2.5mm) 70 A AWS 6011 electrode on AC. 2. Put the [...]

B-15 OPERA TION B-15 BULLDOG™ 140 4. The bead should be put on with a weaving motion, and it should be 1/2-3/4” (12.7-19.0mm) wide. Do not let the arc blow over the edge, as that will dull the edge. (See drawing below.) 5. Use the back-stepping method. Begin to weld 3” (76mm) from the heel of the share and weld to the heel. The second weld wi[...]
