    WARNING: Read and understand all instructions. Failure to follow all instructions listed below may result in serious injury. CAUTION: Do not allow persons to operate or assemble this POWER TIG DPIII until they have read this manual and have developed a thorough understanding of how the POWER TIG DPIII works.
  • Page 4 immerse them in water. These components and the welder must be completely dry before attempting to use them. -Follow the instructions in this manual. -Keep welder in the off position when not in use. -Connect ground lead as close to the area being welded as possible to ensure a good ground. -Do not allow any body part to come in contact with the welding wire if you are in contact with the material being welded, ground or electrode from another welder.
  • Page 5 UV and IR Arc Rays The welding arc produces ultraviolet (UV) and infrared (IR) rays that can cause injury to your eyes and skin. Do not look at the welding arc without proper eye protection. -Always use a helmet that covers your full face from the neck to top of head and to the back of each ear. -Use a lens that meets ANSI standards and safety glasses.
  • Page 6 There are specific applications for which the POWER TIG DPIII was designed. Always check of damaged or worn out parts before using the POWER TIG DPIII . Broken parts will affect the POWER TIG DPIII operation. Replace or repair damaged or worn parts immediately.

    Welders Instructions POWERTIG pulse inverter welder uses inert gases (Argon) as the protection medium for the arc, using high frequency or high pulse to do the gas ionization and melt metals by the arc, made between the tungsten electrode and work piece, to reach the welding purpose. It can give fast good compensation for power grids fluctuation, and can control accurately for various welding process.
  • Page 8 * Welders have strong electromagnetism and electric frequency disturbs. Do not let near the persons with heart pacemaker or easily affected by electromagnetism and electric frequency. * Do not press, pile or stress the welding wires by any apparatus. Do not bend the welding wires into very small angle, otherwise it would hurt the inside wires to cause the hidden troubles.
