A Free copy of “Arc Welding Safety” booklet E205 is available from the Lincoln Electric Company, 22801 St. Clair Avenue, Cleveland, Ohio 44117-1199. BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
  • Page 3: Electric Shock Can Kill

    ELECTRIC SHOCK can kill. 3.a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands.
  • Page 4 WELDING SPARKS can cause fire or explosion. 6.a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas.

    Keeping these contributing factors in mind, installing equipment per the following instructions should mini- mize problems. 1. Keep the welder power supply lines as short as possible and enclose as much of them as possible in rigid metallic conduit or equivalent shielding for a distance of 50 feet (15.2m).
  • Page 10: Input Connections

    4. Keep the torch in good repair and all connections tight to reduce high frequency leakage. 5. The work terminal must be connected to a ground within ten feet of the welder, using one of the fol- lowing methods. a) A metal underground water pipe in direct con- tact with the earth for ten feet or more.
  • Page 11: 230V Input

    230V INPUT The equipment is provided with a 230/115V cable, 6.6ft.(2m) in length with a 230V 6-50P attachment plug. The Invertec V205-T AC/DC performs best when con- nected to 230VAC inputs. This input allows full output of the machine (200 amps). 115V INPUT A suitable 115V attachment plug must be installed on the power cord to use the V205-T AC/DC with a 115V input...

  • Page 20: Output Limitations

    OUTPUT LIMITATIONS The maximum output current as specified in the instal- lation section of this manual is derated in two situa- tions; alternate AC Wave Forms and elevated AC Frequencies. • Alternate AC Wave Forms (See Set Up Menu) Square 200 amps max.
  • Page 21: Dc Electrode Positive Polarity

    DC Electrode Positive Polarity. (Direct Current Reverse Polarity) (see Figure B.5) In this case, there is a continuous flow of electrons from the workpiece to the electrode. The reverse polarity is used for welding alloys covered with a layer of refractory oxide. With this polarity the electrode functions as anode and is subjected to a high degree of heat;...
  • Page 22: Steel Tig Welding

    STEEL TIG WELDING The TIG process is very effective for welding both car- bon steel and alloy steel, especially in applications requiring precision results. DC Electrode Negative Polarity is required. Since this process does not include the removal of impurities, proper cleaning and preparation of the edges is required.
  • Page 23: Protective Gas

    B-10 PROTECTIVE GAS Both argon and helium work when welding aluminum. Argon is preferred, due to its lower cost and consump- tion rate. This gas also tends to stabilize the arc, thus making it easy to operate. For some applications, however, the use of helium, or argon-helium blends, is recommended due to better weld penetration and faster travel speed.
