Bend at joint Cross Section Possible Causes and Solutions 1. Improper clamping: Make sure that pieces are clamped securely in place. Make tack welds to help hold pieces. 2. Excessive heat: Weld a small portion and allow to cool before proceeding. Reduce wire feed speed. Increase weld speed. 10. When the weld is complete, lift the electrode wire clearly away from any grounded object, set the Face Shield down, turn toward the Flux Wire Welder, and turn the Power Switch to the OFF position. 11. Unplug the Power Cord from the electrical outlet. Be sure to set the torch down on a nonflammable, nonconductive surface. 12. The Wire Brush/Hammer (39) can now be used to clean up the weld. CAUTION: The weld may still be quite hot and sparks/chips may fly when cleaning. Be certain to continue to wear ANSI approved safety goggles and protective wear when cleaning a weld. The Hammer can be used to knock off any excess spatter and to help knock down any ridges. Be careful not to damage the weld or material when striking it. The Wire Brush can then be used to help remove oxidation and some fine spatter. Crooked/wavy bead Porosity Small cavities or holes in the bead. Top View Top View Possible Causes and Solutions 1. Stickout too long: Reduce stickout. 2. Inaccurate welding: Use two hands or rest hand on steady surface. Possible Causes and Solutions 1. Stickout too long: Reduce stickout. 2. Dirty workpiece or welding wire: Make certain that workpiece and wire are both clean and free from oil, coatings, and other residues. Excessive Spatter Spatter that is grainy and large. Fine spatter is normal. STRIKE TEST A test weld on a piece of scrap can be tested by using the following procedure. WEAR ANSI GOGGLES DURING THIS PROCEDURE. 1. After two scraps have been welded together and the weld has cooled, clamp one scrap* in a sturdy vise. 2. Stay clear from underneath while you strike the opposite scrap with a heavy hammer, preferably a dead-blow hammer. 3. A good weld will deform but not break. A poor weld will be brittle and snap at the weld. *This test will damage the weld it is performed on. This test is only an indicator of weld technique and is not intended to test working welds. Top View Possible Causes and Solutions 1. Wire feeding too fast: Reduce wire feed speed. 2. Stickout too long: Reduce stickout. 3. Dirty workpiece or welding wire: Make certain that workpiece and wire are both clean and free from oil, coatings, and other residues. Maintenance Warning: Before performing any maintenance on the Welder, unplug the Power Cord from the electrical outlet and allow all parts of the welder to cool thoroughly. 1. Periodically remove the Right and Left side panels (12 and 13), and using compressed air, blow out all dust from the interior. 2. Store in a clean and dry location. 3. For optimal weld quality, clean and inspect the Contact Tip (2b) and Nozzle (3) before each use, as follows: Nozzle Inspection, Cleaning, and Replacement A. Make sure that the entire Torch (parts 1a through 3) is completely cool and that the Power Cord is unplugged from the electrical outlet before proceeding. B. Turn the Nozzle (3) counterclockwise while pulling to remove. C. Scrub the interior of the Nozzle clean with a wire brush. D. Examine the end of the Nozzle (3). The end should be flat and even. If the end is uneven, chipped, melted, cracked, or otherwise damaged, the Nozzle will adversely effect the weld and should be replaced. E. Reinstall the Nozzle (3) after inspecting and cleaning the Contact Tip (2b). Contact Tip Inspection, Cleaning, and Replacement A. Make sure that the entire Torch (parts 1a through 3) is completely cool and that the Power Cord is unplugged from the electrical outlet before proceeding. B. Remove the Nozzle as explained above. Using the third oval hole on the provided Wrench (43), turn the Contact Tip (2b) counterclockwise and slide it off the welding wire. C. Scrub the exterior of the Tip clean with a wire brush. Check that the Tip is the proper type for the wire size used (0.9 mm for .030” wire). D. Examine the hole at the end of the Contact Tip (3) for the following problems: Shape: The hole should be an even circle, it should not be oblong or have any bulges in it. Size: The Tip will decrease in efficiency as the center hole enlarges. A tip that measures 150% or more the original size* should usually be replaced. *13.5 mm or more for 0.9 mm Tips (2b) If any problems are noted, Contact Tip (2b) replacement would be advisable. Make sure to select a new Tip that is the correct size (0.9 mm) for the welding wire used (.030”). E. Reinstall the Tip (2b) and securely reinstall the Nozzle (3) as well.
