TWi-250 Features

• Set-Point Discharge: Unit discharges directly to a new set point without needing to discharge completely
• Universal Input Voltage: Plug and play, no need to re-tap the machine for 110V or 220V input voltages
• Low input voltage capability enables operation with long extension cords
• Contact and Trigger Indicators for fast troubleshooting of hand tool and weld cable maintenance issues
• Thermal and Voltage protection indicators to protect the unit from damage due to overheating or poor input power
• 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 TWi-250 CD Unit weighs less than most other available models for ease of carrying.
