Anleitung Zusammenfassung
Remove the coating from the base metal. b. Make sure that the welding area is well ventilated. c. Use an air-supplied respirator. Extremely toxic fumes are created when these metals are heated. The electromagnetic field that is generated during arc welding may interfere with the operation of various electrical and electronic devices such as cardiac pacemakers. Persons using such devices should consult with their physician prior to performing any electric arc welding operations. ! WARNING . Never wrap arc welder cables around the body. . Exposure to electromagnetic fields during welding may have other health effects which are not known. Always be sure ! WARNING that the welding area is secure and free of hazards (sparks, flames, glowing metal or slag) prior to leaving. Be sure that equipment is turned off and excess wire is cut off. Be sure that cables are loosely coiled and out of the way. Be sure that all metal and slag has cooled. ADDITIONAL SAFETY STANDARDS ANSI Standard Z49.1 from American Welding Society, 550 N.W. LeJune Rd. Miami, FL 33126 Safety and Health Standards OSHA 29 CFR 1910, from Superintendent of Documents, U.S. Government Printing Office, Washington, D.C. 20402 National Electrical Code NFPA Standard 70, from National Fire Protection Association, Batterymarch Park, Quincy, MA 02269 Safe Handling of Compressed Gases in Cylinders CGA Pamphlet P-1, from Compressed Gas Association, 1235 Jefferson Davis Highway, Suite 501, Arlington, VA 22202 Cutting And Welding Processes NFPA Standard 51B, from National Fire Protection Association, Batterymarch Park, Quicy, MA 02269 Safe Practices For Occupational And Educational Eye And Face Protection ANSI Standard Z87.1, from American National Standards Institute, 1430 Broadway, New York, NY 10018 Installation LOCATION Selecting the proper location can significantly increase performance, reliability and life of the arc welder. . For best results locate the welder in an environment that is clean and dry. . Store flux core wire in a clean, dry location with low humidity to preserve the flux wire coating. . The use of an extension cord is not recommended for electric arc welding machines. The voltage drop in the extension cord may significantly degrade the performance of the welder. Assembly HANDLE ASSEMBLY 1. Pull rod on both sides of wire feed Figure 2 - Handle Assembly door and lift to open. 2. Bolt plastic handle caps to cover as shown (Figure 2). 3. Slide metal handle through caps and attach with screws. Ground Clamp 1. Loosen hex bolt on work clamp. 2. Insert cord (labeled work on the front panel of the welder) through clamp handle and slide bare wire under the clamp block. Tighten hex bolt making sure bare wire is clamped securely (Figure 3). 3 Wire Feed Arc Welder Figure 3 - Ground Clamp Assembly Flux Core Wire Installation Welding power ! WARNING is applied to the output terminals, feed roll, ground clamp, gun cable connection and welding wire even when the gun switch is not activated. Do not touch these parts when the welding machine is on. NOTE: Before installing welding wire, be sure that the diameter of the welding wire matches the contact tip in the end of the gun. The wire size is marked on the contact tip in inches or Contact Tip Markings Wire Size mm .030” or .8 .035” or .9 mm. (See chart below). 1. Verify the unit is off and lift the door on the welder to expose the wire feed mechanism. 2. Remove the spool quick lock, by pushing in and rotating 1/4 turn counterclockwise. The knob, spring, and spool spacer can now be removed. 3. Loosen the wire feed tensioning screw on the drive mechanism. This allows initial feeding of the wire into the gun liner by hand. 4. Install the wire spool onto the spindle so that the wire can come off the spool on the end closest to the wire feed guide tube. Do not cut the wire loose yet. Install the spool spacer, spring, and quick lock knob by pushing in and turning the knob 1/4 rotation clockwise. 5. Hold the wire and cut the wire end from the spool. Do not allow the wire to unravel. Be sure that the end of the wire is straight and free of burrs. 6. Feed the wire through the wire feed guide tube, over the groove in the drive roll and into the gun liner. Tighten the wire feed tensioning screw so that it is snug. Do not over tighten. Spool Lock Spool Spring Spacer Guide Tube Tension Screws Figure 4 - Weld Wire Routing 7. Remove the nozzle by turning counterclockwise. Then, unscrew the contact tip from the end of the welding torch. (See Figure 6). Plug the welder into the proper power supply receptacle. 8. Turn on the welder and set the wire speed rate to 8. Activate the gun switch until the wire feeds out past the torch end. (See Figure 5.) Turn welder off. Tension Screw Figure 5 - Wire Feed Gun 9. Carefully slip the contact tip over the wire and screw it into the torch diffuser. (See Figure 6.) Install the nozzle by twisting clockwise. Cut the wire off approximately 1/4 inch from the end of the nozzle...
