AC/DC Welding Capabilities

 LONGEVITY® has both hobbyists and the professional welders in mind with the INNOVATOR® 255i. This compact versatile unit offers the user a vast array of controls to accurately set the welder to perform under a wide variety of situations including some fine aluminum welding.

Advanced Pulse TIG Function

 Pulse welding helps with thin gauge metals along with heat sensitive metals. Pulse welding lowers average
temperatures allowing the user to weld thin material
focusing the arc and allowing for proper distribution of
the heat. This feature also limits the arc cone diameter to a precise area which provides control of the arc.

Efficient IGBT Inverter Technology

Inverter technology emphasizes portability, yet the
efficiency and reliability of the Soft Switching IGBT
components allows for the ultimate welding experience.

Stick With Adjustable Arc Force

With Arc Force, you are able to adjust the inductance of
the arc for either a crisp arc or soft arc with a fluid puddle. This will allow for greater control of your welding parameters.

40 Amp Plasma Cutter

The INNOVATOR® 255i has a 40 amp plasma cutter capability that makes it perfect for the fabricator, all you need is this one compact and light unit for all of your projects needs.

Synergistic Control Panel

The key feature of the control panel is the logical way in
which the controls are aranged all the parameters needed for day to day welding can easily be selected. The INNOVATOR® 255i is one of the more versatile welders on the market.

High Frequency or Lift Arc start

The INNOVATOR® 255i offers the ability to start the arc with lift start which is also ideal to use around electronic devices which may be sensitive to high frequency interference.

2T/4T Operation

The LONGEVITY® INNOVATOR® 255i allows excellent
control whether you are using a TIG torch, the panel or
the hand switch control. With the 2T/4T function you can
control your arc to the next level. Depending on switch
position, the switch will allow the welder to not have to
hold the trigger to continue welding easing welding for
long period of time.
