Introduction
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. The INNOVATOR 255i allows the welder to set features like AC frequency and balance control, pulse control, and both "up" and "down" slope control, effortlessly with our fully synergistic control panel.
Quick Setup Connections
Longevity offers a quick connection of your torches by using DINSE connectors giving the users total versatility due to it being compatible with most aftermarket torches. Setup time is also reduced due to the quick connect argon couplers.
Advanced Pulse TIG Function
Longevity has added pulse capabilities to the INNOVATOR 255i for the convenience of the user. 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 the proper distribution of the heat. This feature also limits the arc cone diameter to a precise area which provides control of the arc.
Digital Amp and Volt Meter
By using digital meters, Longevity gives the operator instantaneous outputs which are easily read while welding. This allows the user to dial-in their favorite settings accurately, again, and again!
Efficient IGBT Inverter Technology
With inverter IGBT technology, Longevity has once again revolutionized the industry by producing a portable, yet powerful machine that can be operated with a generator, perfect for the ON-THE-GO welding. Inverter technology emphasizes portability, yet the efficiency and reliability of the Soft Switching IGBT components allow for the ultimate welding experience.
High Frequency 40 AMP Plasma Cutter
The INNOVATOR 255i uses the tried and true method of high frequency to start the pilot arc. high frequency is quicker and more reliable than other methods used. High frequency allows for non-contact starting.
High Frequency or Lift-Arc start
The INNOVATOR 255i is safe to operate near hospitals or any other area where high-frequency interference may cause issues. 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.
Thermal Overload Protection
If you are welding for a long period of time and your duty cycle limit is reached, Longevity's thermal overload protection will kick on safely shutting down your machine for proper cooling avoiding any damage. Once it cools, you will be able to weld again!
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 a long period of time.
Power Faction Correction (PFC)
With the INNOVATOR 255i, you are able to easily switch over from either 220v or 110v. With our newer model design, simply plug the 110v attachment to the existing power cord and weld away anywhere, anytime (110v/220v adapter is not included).
Synergistic
The key feature of the control panel is the logical way in which the controls are arranged 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 and it is backed by Longevity's industry leading warranty!
