. Keep cylinders away from any welding or other electrical circuits. . Never allow a welding electrode to touch any cylinder. . Use only correct shielding gas cylinders, regulators, hoses and fittings designed for the specific application; maintain all parts properly. . Turn face away from valve outlet when opening cylinder valve. . Keep protective cap in place over valve except when cylinder is in use or connected for use. . Read and follow instructions on compressed gas cylinders, associated equipment, and CGA publication P-1 listed in Safety Standards. Never use flammable gasses with MIG welders. Only inert or non-flammable gasses such as carbon dioxide, argon, helium or mixtures of one or more of these gasses are suitable for MIG welding. Never lift cylinders off the ground by their valves or caps or with chains or slings. ADDITIONAL SAFETY STANDARDS ANSI Standard Z49.1 from American Welding Society, 550 N.W. Le June 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 Code for Safety in Welding and Cutting CSA Standard W117.2, from Canadian Standards Association, Standards Sales, 178 Rexdale Boulevard, Rexdale, Ontario, Canada M9W 1R3 Cutting And Welding Processes NFPA Standard 51B, from National Fire Protection Association, Batterymarch Park, Quincy, MA 02269 3 Wire Feed Arc Welder General Safety (Continued) 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 Refer to Material Safety Data Sheets and manufacturers instructions for metals, wire, coatings and cleaners. Installation LOCATION Selecting the proper location can significantly increase performance, reliability and life of the arc welder. . For best results locate welder in a clean and dry environment. Dust and dirt in the welder retain moisture and increase wear of moving parts. . Place welder in an area with at least twelve inches (305 mm) of ventilation space at both the front and rear of unit. Keep all obstructions out of this ventilation space. . Store welding wire in a clean, dry location with low humidity to prevent oxidation. . Use a properly grounded receptacle for the welder and ensure welder is the only load on power supply circuit. Refer to chart on page 1 for correct circuit capacity. . Use of an extension cord is not recommended for electric arc welding machines. Voltage drop in the extension cord may significantly degrade performance of the welder. Assembly TORCH INSTALLATION (See Fig. 2) 1. Make sure unit is off and unplugged. 2. Feed the connectors for the torch switch through the hole in the control panel. These leads are to be fed up over the polarity studs and through the hanger on the center wall. 3. Insert the brass torch connector through the hole in the control panel and into the drive deck. Make sure the connector is inserted fully into the drive deck. Loosen the torch clamp knob a few turns if the connector will not insert fully. Tighten the torch clamp knob securely after the brass torch connector is fully inserted. Figure 2 - Torch Installation 4. Connect the torch switch connectors to the two 1/4" terminals in the center wall. Polarity is not important. Make sure these wires do not interfere with the polarity studs or drive deck. WORK CLAMP INSTALLATION (See Fig. 3) 1. Remove one hex nut from work clamp. 2. Slide welding cable with ring connector through hole in work clamp. 3. Attach ring connector to work clamp with hex nut removed in step 1. Hanger Torch switch leads Torch clamp knob Torch switch connectors Drive deck Torch switch terminals Torch Hex Nut Work clamp Welding cable Ring connector Figure 3 - Clamp Installation 4 Assembly (Continued) WIRE INSTALLATION NOTE: Before installing welding wire, be sure: a. Diameter of welding wire matches groove in drive roller on wire feed mechanism (See Fig. 4). b. Wire matches contact tip in end of torch (See Fig. 5). A mismatch on any item could cause the wire to slip and/or bind. NOTE: Always maintain control of loose end of welding wire to prevent unspooling. 7. Unscrew nozzle and contact tip from end of welding torch (See Figure 5). Plug welder into a proper power supply receptacle. 8. Turn on welder and set wire speed to 10. Activate torch trigger until wire feeds out past the torch end. Turn welder off. 9. Carefully slip contact tip over wire, screw tip into torch end and reinstall nozzle (See Figure 5). Cut wire off approximately 1/4 inch from nozzle end. DUTY CYCLE / THERMOSTATIC PROTECTION Welder duty cycle is the percentage of actual wel...
