TWE-321 Features

  • Digital DC Voltage read-out on all models (allows for more accurate and repeatable weld settings).
  • Cooling Fan in all models for increased efficiency.
  • Dial-down DC voltage settings (no need to turn off the unit when resetting to a lower voltage).
  • Only 10 amp circuit requirement (unit fused at 10 amps).
  • 99,000 micro farad capacitors charging to 200 VDC for greater power output at lower DC voltage requirements.
  • Terminal connections on capacitors are over 5/8" in diameter for a good seat of the terminal buss bars to increase reliability.
  • Terminal connections on capacitors have 1/4-20 socket set screws inserted into each one. The socket set screw is used to make the connection to the buss bars. This eliminates damaging the threads in the aluminum connections of the capacitor, assuring a solid contact connection.
  • Rigid internal construction connecting the the entire internal unit to the front and rear panels minimizes the opportunity of the components coming loose during handling or operations.
  • Sheet metal is powder-coated for greater durability, texture, and appearance.
  • CD Stud guns are ergonomically designed for better hand fit and comfort which reduces operator fatigue for increased weld repeatability.
  • CD Stud guns have a permanent internal spring with easy adjustment for various spring pressures for applying the correct spring pressure to the weld.
  • CD Stud guns can be configured for "B" collets, "CI" collets, Euro collets, or standard tapered chucks.
  • The TWE-321 CD Unit weighs less than most other available models for ease of carrying.
